On Tuesday night, Dr. Drew spoke to the photographer who snapped the last picture of Michael Jackson inside the ambulance the day the pop star died.

While they walked outside Jackson’s former rented Holmby Hills mansion, Dr. Drew began the conversation by asking Ben Evenstad what sort of things he would look for before that tragic day.

“We were either looking for a doctor's visit because we could always get pictures there, or a shopping trip,” he said.

Evenstad also noticed that Jackson was rehearsing months before his death.

“That started about five to six months [prior],” he said.

Dr. Drew commented on how so much had been made of the few days before Jackson passed away – the notion that he had been in such good shape. “[So] he had been rehearsing for quite some time,” Drew said.

Drew also mentioned how Jackson could sometimes be heard rehearsing in the mansion at night. He was reportedly known for being a night owl.

“He would stay up late,” Evenstad said. “I had a conversation with one of the members of the security staff that indicated there were many times where they took him out where nobody was here, meaning very, very late at night – three in the morning.“

Did this mean that Jackson's sleep problem was already well established?

Dr. Drew asked Evenstad if he had seen anyone making trips pharmacies.

“We would follow security staff,” Evenstad said. “A lot of times they would do advance work – go to a store [or] movie theater. We wanted an idea of what Michael would do later. Often times they would go to pharmacies [and] pick up various things.”

Evenstad said he could never see what was picked up because “they were smart enough to not let that picture out.”

Later, the two began speaking about the day Jackson died.

“One of my photographers was here posted early in the morning,” Evenstad explained. “Shortly after noon, he saw the ambulance arrive [and a] fire truck parked outside ... He alerted me [that there was] an ambulance at the house. At that time we had no idea ... it could be anything ... I got here in like 10 minutes.”

Drew asked if Evenstad was aware that something was seriously wrong.

“At first, we thought maybe one of the kids is sick – maybe one of the staff is sick,” he recalled. “Through the fire truck outside, we could see the computer monitor and it said ‘50-year-old male not breathing’, – knowing Michael was 50 years old, we thought, ‘OK, this is probably Michael.'”

Evenstad went on to say that he noticed Dr. Conrad Murray coming to the residence for a couple of months and that Murray was with Michael Jackson in the house for a long time.

“I heard some of the fans say they would see Michael Jackson leave five or six times a day ... go to the dermatologist's office,” Dr. Drew said.

Evenstad said Jackson would “be in the building where Dr. Arnold Klein is” ... almost once a day for up to three hours.

“I am a physician,” Dr. Drew said. “I don’t know of any condition that requires a daily dermatology visit over long periods of time.”

At the end of the interview, Evenstad, a man who observed how the place operated, was asked if he had insights as to how Conrad Murray and Michael ran their day.

“All the days were pretty similar,” Evenstad said. "The guards came and went at the same time. Murray came and went at the same time. Michael, when he was going to rehearsal, would be on a fairly consistent schedule. So my guess is, from an outsider's perspective, whatever was going on in there, was something that happened every day or every night and this one time it went bad and they weren’t prepared for it.”

A little girl vanishes from her home in suburban Phoenix while her mom reportedly steps away to run an errand.

Nearly two weeks have gone by and no one has seen 5-year-old Jhessye Shockley.

Some people have been pointing fingers at Jhessye’s mom, Jeurice Hunter, who has spent time in jail after pleading no contest in California to abusing her other children, according to the New York Times. Jeurice has not been named a suspect in anything related to Jhessye's case.

On Thursday night, Jhessye’s grandmother Shirley Johnson, and aunt Josie Hunter, spoke out on Dr. Drew’s HLN show.

Josie was asked if she thought Jeurice was involved in some way or may have even abused Jhessye.

“If the police find evidence of whoever did it, including Jeurice ... [they] should be held accountable,” Josie said. “I cannot say I know for sure that Jeurice did this or anything like that. I want them to look at everyone. I don't know what happened. I was not here. That's why we're looking to detectives and investigators to find this out …and if they feel that she has done something, then get the evidence and bring it out front and do what you have to do ... She [Jeurice] has a past, and I don't agree with it.”

Jhessye’s cousin recently made this comment to local TV station KNXV.

“At our get-togethers, Jhessye was not herself,”’ Lisa Vance said. “I’ve seen marks on Jhessye that led me to believe she was being abused in Jeurice’s home. “

Shirley Johnson was skeptical of the remarks.

“Well, if she's being the loving cousin that she says she is ... why didn't she call somebody for help for Jahessye?” Johnson asked. “If she loved Jahessye so much, why did she let Jahessye stay in that situation and not make me aware [or] the authorities aware at all? So I take that with a grain of salt.”

Johnson went on to voice her other concerns.

“The Glendale Police Department needs to have a magnifying glass over how they handled this whole case,” she said. “We need to look at how the nation looks at little African-American children coming up missing ... who gets the most attention?“

It has also been noted that Jahessye's father George Shockley is a convicted sex offender currently serving time in a California prison, according to KPHO.

A $16,000 reward has been posted for information leading to the return of Jhessye.

She is about 3 feet 5 inches tall and around 55 pounds.

Anyone with information is urged to call 623-930-HELP.

Baby Lisa's half-brothers, who were at the family's home the night Lisa disappeared, will be interviewed by a child services specialist Friday.

The boys, 8 and 6, were previously interviewed just after Lisa disappeared, both for under an hour.

In an NBC interview, Baby Lisa’s mother, Deborah Bradley, said the boys heard noises the night Lisa disappeared. Bradley didn’t want to talk to her sons about the incident because she was reluctant to put them through "anything else."

In the same interview, Bradley also said she was drunk the night Lisa disappeared and that she had last seen the baby about four hours earlier than initially reported.

On Wednesday night, Dr. Drew invited HLN host and former prosecutor Nancy Grace to his HLN show to discuss the oddities that have been reported, so far, in this case.

“Number one, you've got two boys living in the home the night baby Lisa goes missing,” Nancy said. “The 8-year-old belongs to the male live-in. The 5-year-old is mommy's bio-baby.”

“And by the way, to a man to whom she's still married,” Dr. Drew interjected.

“They say they don't have enough money for a divorce ... FYI, you can do it online pretty much these days,” Nancy jokingly replied. “But long story short, when cops first found out baby Lisa's missing, they interview one child for 30 minutes, the other child for 50 minutes. That's not enough. And since that time, until the present, mommy and daddy have stonewalled the cops from talking to the children. They say they don't want the children traumatized. Mommy also says she said nothing to the children about baby Lisa missing ... I don't believe that.”

Dr. Drew told Nancy how peculiar those notions sounded.

“The first thing the kids would be doing [is saying]: ‘Where's Lisa?’" he said. “You would be dealing with that every day ... again, that's more of the mom’s bizarre behavior."

Nancy then mentioned how she didn’t like the fact that the parents weren’t talking to police separately.

“In order for mommy to talk to cops, she's got to have daddy there ... Why?" Nancy asked. "They are not suspects, but this is not helping move the investigation off them."

“Whether she's a suspect or not, these are adults in charge of the care of children who don't remember what they did the night they were supervising these kids ... that whole business of [possibly] drinking to the point of blacking out is very disturbing,” Dr. Drew added.

The two went on to speak about the alleged ex-friend of Deborah Bradley who says Bradley has a good heart, but is a “very good con artist.”

“For one thing, I wouldn't put anybody, especially in-laws, up on the stand because it's just like two wet cats in a barrel,” Nancy said. “You're going to get all these distant relatives and the sister, ‘oh, she didn't – she re-gifted me at Christmas – I hate her – she's manipulative.’ I don't care about that. All I care about is the evidence."

Drew then asked Nancy what is needed to move the investigation forward.

“Number one, I need mommy to man up and talk to cops without daddy holding her hand,” Nancy said. "I've also got a problem with mommy saying i was blacked out drunk and mommy saying i flunked a polygraph on the question" 'Do you know where baby Lisa is?' That's a problem to me.”

Nancy did mention that she cannot ignore that people in the neighborhood saw a man walking with a baby that night ... and that a cadaver dog “hit” on an area of the carpet in Deborah’s bedroom.

Between 30 and 50 investigators are now involved in the search.

A family attorney says the couple has provided a wealth of information to police and that they want people to continue looking for the child.

The defense called Dr. Allan Metzger to the stand Monday to show the jury that Michael Jackson was seeking and getting drugs from other doctors at the same time Dr. Conrad Murray was working as his full-time physician.

But when the prosecution began questioning Metzger, his testimony appeared to be working in their favor at certain points.

"Is there any amount of money that would have convinced you to give him intravenous propofol in his house?" district attorney David Walgren asked.

"Absolutely not," Metzger answered.

truTV's In Session host Ryan Smith, who appeared on Dr. Drew Monday night, was quick to comment on Metzger’s statements.

“It just goes to show that even with this witness being a defense witness, he [Dr. Metzger] came off like a prosecution witness because he said ‘no matter what was going on here, I never would have done what Conrad Murray did,' and he said he wouldn't do it for money,” Smith explained. "That really hammered home a point."

Dr. Drew then told his viewers why he wanted to make sense of some of the troubling aspects of this trial.

“First of all, Dr. Metzger giving Michael Jackson benzodiazepines ... that to me is like ‘you got to be kidding me,' he said. “This guy is struggling with a serious history of addiction – clearly in drug withdrawal – [something] that everyone is calling insomnia ... it is drug withdrawal.”

Dr. Drew then held up transcripts of Dr. Murray's 2009 police interview.

“Then Dr. Murray, with the police, says ‘well, I knew Dr. Klein and Dr. Metzger were prescribing drugs, but Michael wanted to keep it quiet or keep it to himself’, Drew noted. “Why didn't he call the other doctors? That's all he had to do. If I were Dr. Metzger, I would be beside myself, angry all that stuff was going on in a patient that I was prescribing to without my knowledge.”

Ryan Smith said that sort of frustration did not come out in Dr. Metzger's testimony Monday.

“I got the sense he was trying to avoid being tied to this in any way,” Smith said.

Dr. Drew agreed and proceeded to hold up a condom catheter.

”They're trying to prove negligence, but doing very little conversation about the quality of medical care ... I get so frustrated with this case,“ Drew said. “I have to tell you. I have a thing I keep on hand to remind me how outrageous it was, This man, Michael Jackson, went to bed every night with this because he was so sedated that he couldn't function. He couldn't get up to go to the bathroom. As an addictionologist – all the multiple prescribing doctors not communicating with each other – bad timing – Michael Jackson got the worst my profession has to offer.”

Defense lawyers will use the next few days to challenge the prosecution's contention that Dr. Conrad Murray's alleged reckless use of propofol to help Jackson sleep makes him criminally responsible for the pop star's death.

Is there a possible break in the baby Lisa case?

According to a police affidavit released Friday, a cadaver dog searching Lisa’s family home indicated a positive hit. That means the dog reacted to the scent of a deceased human.

Police haven't named any suspects, but a neighbor and other witnesses are saying they saw a stranger leaving the home with a baby in just a diaper on October 4.

CNN correspondent Sandra Endo, who was live in Kansas City, MO, reported on Dr. Drew that a statement was released from the lawyer of baby Lisa’s family.

“[It stated] that the police affidavit that was released today … [is] unfortunate and … that the parents feel it will derail the search for the missing girl,” Endo said.

Endo also noted that a prayer vigil was held earlier in the night in front of baby Lisa’s home. The grandparents of Lisa and Ashley Irwin, Jeremy Irwin’s sister, were among those in attendance. There were tears, prayers, and hopeful, optimistic comments made by family members. They say they're hopeful that investigators will find baby.

Ashley Irwin said “they don't want the media to blame the family, especially Deborah Bradley,” Endo explained. “But Ashley did say the family – the parents – are cooperating … and the parents have been in constant contact with investigators as recently as today, October 21, which is contrary to several media reports.

Later, criminal defense attorney Mark Eiglarsh made mention of the witnesses who noticed a man holding a baby the night Lisa disappeared.

“I call it the defense witness lottery,” Eiglarsh said. “She [Deborah Bradley] won it. Whether she's guilty or not – to actually have three people, two separate locations, to actually [have] someone of a physical build, five-foot-seven, 140-pounds, that could slip through the window. Keep in mind, a 350-pound person holding a baby isn’t making it through that window. This to me is compelling for the defense. It still doesn't mean she's innocent or guilty. It just means come game day, if she's ever charged, these are compelling witnesses for the defense.”

Dr. Drew stated that he once again, getting a real sense of chaos. “Substances, chaos, vortex – sounds familiar, doesn't it? It is like Casey Anthony all over again,” he said.

Baby Lisa’s family members continue to stay at a relative's home not far from their residence on the 3600 block of North Lister Avenue.

More than two weeks have passed since Lisa’s parents reported her missing from her crib in the middle of the night. Bradley said she last saw the baby girl before going to sleep around 6:40 p.m. October 3 and Lisa’s father said she was gone when he got home from an overnight shift at work around 4 a.m. on October 4.

Anyone with information about Lisa’s disappearance should call the TIPS Hotline at 816-474-8477.

After reprimanding Lindsay Lohan for her failure to comply with community service, an LA County judge revoked Lohan’s probation on Wednesday morning.

Lohan was removed from the courtroom in handcuffs, but was later freed after posting $100,000 bail.

On Wednesday night, HLN’s Dr. Drew and his guests weighed in on the situation.

“We're watching her die in my opinion,” Dr. Drew said. "I know her parents. I feel for them.”

Jen Heger, legal editor for Radaronline.com, added that she’s a young woman who is clearly in distress.

“I believe that her failure to not comply with the court's orders is essentially a cry for help,” she explained. “Judge Sautner said to her today, ‘you know, Lindsay, from what I hear, you're an actress. Are you? You're a supposed actress?’ That's very sad for the judge to publicly say that to her.”

Heger mentioned that Lohan looked "really bad" while she sat in the courtroom today.

“Her face was bloated,” Heger said. “Her eyes looked bloodshot. She's had issues with her teeth in the past several weeks.”

There had been some speculation that methamphetamines were part of the picture. But if that’s the case, Dr. Drew said it was his fear that she could possibly be getting prescription drugs and she could be justifying using medicine because doctors are prescribing those medications.

“It's a Michael Jackson story all over again and it happens all the time with celebrities,” Drew said. “I'm here screaming about it every night.”

But does Lindsay even understand what her obligations are or is she just playing cat and mouse? Dr. Drew inquired.

"Unfortunately, it could be a combination of both,” former LA County Deputy District Attorney Danette Meyers said. “The last time I had the case, I was hoping that she would follow the court's instructions. Judge Sautner gave her a break. This wasn't the kind of case you give a person a break on. She didn't need a break. What she needed was someone to really catch her attention and say ‘get yourself together. You have a lot going for you. Get it together before you kill yourself.'"

Meyers believes if she did serve some time in custody, it might get her attention.

“I know a lot of my patients find recovery when they lose their freedom,” Dr. Drew added. “I have faith for every patient. I have hopes for poor Lindsay Lohan. But I just get this terrible feeling that something horrific is going to happen to her. Not necessarily death – maybe something worse. I keep thinking about her losing a limb or something awful because her disease is recalcitrant, reckless, and we're all watching it live."

Lohan was supposed to be performing community service at a downtown Los Angeles women’s center, but the judge said that Lohan posted nine excused absences at the center since her last court hearing on July 21 -and performed, at most, only two hours of service.

Lohan’s attempt to perform community service at a nearby American Red Cross facility were voided because the judge said she didn’t authorize that change.

Investigators executed a search warrant Wednesday at the home where baby Lisa vanished from her crib two weeks ago.

We now know that Lisa's mom, Deborah Bradley, may have had more than a few drinks the night her child went missing. She is also on anti-anxiety meds and admits that she drank to the point of possibly blacking out.

“I think baby Lisa's parents are hiding something,” Dr. Drew stated on his HLN show Wednesday night. “The drinking revelations are the tip of the iceberg.”

Dr. Drew went on to say that he had spoken with a member of Bradley's family this week and was told that “Lisa's family has a long history – multiple generations of severe abuse, abandonment, neglect, and alcoholism and drug addiction.”

Time will tell whether that figure into this situation.

Later in the show, the panel turned their attention to another aspect of this case – the neighbors.

“Apparently, if you remember, there was a neighbor with [Deborah Bradley} all the way until she went to bed, and the neighbor actually was reporting when the lights went off in the house and what not,” Drew said. “I kept asking, ‘who's this neighbor person?’... I can't confirm this, but from a source told me, that the neighbor's estranged from her husband and the husband was not allowed home that night and that there was some acrimony with the neighbors.”

Could that bit of information shed some light in the direction that police should be following? Criminal defense attorney Mark Eiglarsh weighed into the conversation.

“Statistically, it's less than a fraction of one-percent of those who report their child missing that actually goes missing by a stranger like she's (Deborah) alleging,” he said. "So statistically, it doesn't look likely that her story is true. But if the child does go missing by a stranger, they usually get the child back ... I'm not convicting her ... right now, there isn't proof beyond a reasonable doubt.”

Criminal defense attorney Lauren Lake chimed in saying that Dr. Drew really hit home with something that had been on her mind.

“This whole drinking with the neighbor on the stoop and the neighbor knowing what time the lights went off ... I'm thinking to myself, ‘wow, a neighbor could also know the floor plan to your house and a neighbor could also potentially get past dogs barking because the dogs would be familiar with the neighbor,’” Lake noted. “I'm not saying I'm accusing the neighbor. What I'm saying is, there are other people in the vicinity that I think the police should also look at in addition to the parents."

CNN Correspondent Jim Spellman thinks the neighbor is essential.

“We don't know exactly which neighbor it is, but the very next house next door, we know police have been searching in there,” he said. “They took dogs in there just a few days ago and came out with some bags. We understand it's not evidence, but material that the search dogs use when they go to another location. I think that neighbor is very essential and the two boys that were also in the home with her – they won't let them be interviewed either by police. They might know the most of anybody if the mom really was that drunk.”

More than two weeks have passed since Lisa’s parents reported her missing from her crib in the middle of the night. Bradley said she last saw the baby girl before going to sleep around 6:40 p.m. October 3 and Lisa’s father said she was gone when he got home from an overnight shift at work around 4 a.m. on October 4.

Authorities say they have a warrant to search the family home of missing 11-month-old Lisa Irwin while barring the parents from re-entering their residence in Kansas City, MO.

On Tuesday evening, police cars could be seen in front of Deborah Bradley and Jeremy Irwin's home on North Lister Avenue for several hours. Although police have searched it before, they didn’t have to get the parent's consent this time because they have that search warrant.

In Session's Ryan Smith asked criminal defense attorney Mark Eiglarsh on "Dr. Drew" whether it was common for authorities to keep people out while they conduct their search.

“Absolutely!” Eiglarsh responded. “It would shock me if somehow they allowed the family access to the home during a search ... 100-percent – they keep them out.”

Eiglarsh went on to explain why this is such a significant development.

“They have a search warrant," he stated. "That means a judge signed off on their right to search for specific items. They have something in mind, and hopefully this will lead to further the investigation.”

The parents know that they're not suspects at this point, but they do know they're being looked at.

Psychologist Lisa Boesky put things into perspective.

“Think about it ... most people, when their child goes missing say, 'come in … overturn everything … turn my place upside down,' ” she said. “They're taking it personally and getting defensive that people are looking at them so closely, which statistically, we know, that's why the police look so closely, because often times the family is involved."

Boesky then noted two things.

“Her name is baby Lisa, but the parents in the interview often say ‘she,’ [and] ‘her,’ Boesky said. “It is interesting if you listen to interviews. They don't say 'Lisa' very often. What does that mean? They're distancing themselves from the baby ... I wonder if there's some psychological distancing they're doing by not saying her name. [It’s] incredible when you think about that.”

Bradley and Irwin are reportedly staying with a relative a few miles away. It is not certain how long they have been barred.

More than two weeks have passed since Lisa’s parents reported her missing from her crib in the middle of the night. Bradley said she last saw the baby girl before going to sleep around 6:40 p.m. October 3 and Lisa’s father said she was gone when he got home from an overnight shift at work around 4 a.m. on October 4.

The defense team in the Conrad Murray trial is taking time Tuesday to study new lab test results the prosecution contends show Michael Jackson did not ingest a fatal overdose of sedatives.

The testing was ordered at the request of the prosecution after Murray's defense argued that Jackson swallowed eight tablets of the sedative lorazepam.

The results show "a much smaller amount of lorazepam in the stomach that is totally inconsistent with oral consumption of lorazepam tablets," Deputy District Attorney David Walgren revealed at a hearing Monday.

But on Monday night, one of Dr. Drew’s guests explained his surprising take.

“I am one of the few people that say the new evidence is beneficial to Conrad Murray,” criminal defense attorney Mark Eiglarsh said. “Yeah, I said it. I’ll tell you why. If this judge allows this to come into evidence at this point in the trial, it almost guarantees Conrad Murray a free trial. This is coming back on appeal.”

Eiglarsh went on to say that only in “cheesy courtroom television drama” can you have a trial by ambush.

“They have to give it before opening statement, so you don’t have trial by ambush,” he explained. “If it comes into evidence, you will hear [an] appellate court that will say 'ineffective counsel' for letting it in or say it should have been provided in discovery prior to the trial beginning.”

However, Trent Copeland, who is also a criminal defense attorney, said that he didn’t think it is a "trial by ambush."

“I think what will happen [is] they’ll make it an issue on appeal,” Copeland said. “The fact is, they have to make it an issue that confuses the jury. The reality is that the defense had an opportunity to conduct their own tests, the prosecution conducted their own tests and now they have to fight tout in court over who believes their test is the most appropriate test.”

Eiglarsh later said that when the defense gave the opening statement, they were relying on what was available at the time ... and that it is fundamentally unfair.

“There are bends in the road in every trial,” Copeland stated. "Issues come up that the judge, defense, prosecution have to get together and figure out, 'how are we going to confront this issue?' Mark, you know as well as I do that the reality is the defense has an opportunity [to] now to go back and do retesting if necessary or argue the science.”

The trial, in its fourth week, is still expected to conclude with the start of jury deliberations next week.

If convicted of involuntary manslaughter, the maximum sentence Murray could face is four years in prison and the loss of his medical license.

Last week, we heard tapes of Dr. Conrad Murray being questioned by detectives. In that interview, Murray stated that Michael Jackson was his friend.

A few other physicians who treated Jackson have also claimed to be friends with the superstar. On Wednesday night, Dr. Drew addressed this very issue on his HLN show.

“Doctors [become] so dazzled by special patients,” Dr. Drew said. “My advice to my peers when they're treating celebrities, don't treat them any differently than anybody else. The standard of care of the medicine is the standard because it is the best and if we do anything other than the standard that we offer to all our patients, we're doing something substandard or potentially substandard.”

Guest Dr. Mark Urman, cardiologist and board member of the American Heart Association agreed, saying that it’s "very easy to get enamored" with somebody who's famous.

“I don't get enamored by it,” Dr. Drew said. “It's more difficult. They're more demanding ... you have to hold firm, hold fast.”

Dr. Mark Urman added that it's all about boundaries.

“You have to make it clear, and I do this with all my patients, that there are certain things that are allowable [and] there are certain things that aren't,” he said. "Just because somebody is trying to press you into doing something, you know, is not right, you feel uncomfortable about it, and it's not good medical practice. You've got to take a stand.”

Dr. Drew summed up his thoughts later in the show by stating: “You can't be physician and friend ... it’s dangerous. Boundaries become unclear ... and when people have a substance problem, that's where it really goes off the rail.”
