Tupac Shakur autopsy photos shown at Las Vegas murder trial after some family members leave court

Some members of Tupac Shakur's family stepped out of the courtroom Tuesday before prosecutors showed photos from his autopsy at the Las Vegas trial of Duane "Keffe D" Davis, who is charged with orchestrating the 1996 drive-by shooting that killed the rap giant.

Others remained in the courtroom to face the grim facts of what happened to his body.

Davis, 63, could get life in prison if he's convicted of murder with a deadly weapon with the intent to promote, further or assist a criminal gang. He has pleaded not guilty. His lawyer in the defense opening called the prosecution's narrative "fiction."

Lawyer Michael Sanft told jurors Davis wasn't previously charged, despite implicating himself in interviews and his memoir, because law enforcement knew that he was "full of crap."

Medical examiner testifies about Tupac Shakur's autopsy

Dr. Lisa Gavin, a forensic pathologist and medical examiner for Clark County, Nevada, was among the early witnesses on the second day of testimony. Jurors were shown a photo of a green body bag at the beginning of her questioning, followed by a grisly photo of his body. Some relatives who remained in the courtroom looked away. One woman got up to leave once the photos were shown.

Shakur's cousin Zayd Akinyela said he wanted to stay in court to learn more.

"I feel like the details, especially for people that are close to him, honestly for me helps, helps the grief process. I think we've been waiting 30 years to grieve properly," Akinyela told The Associated Press outside the courtroom. "A lot of people don't get to grieve until they understand what happened to their loved one and how it happened." He added, "That's why I wanted to stay and just see for my own personal closure."

Akinyela said he hadn't known how many times his cousin was shot and can't help but think of the ways the night could have played out differently.

Gavin described three bullets, one of which traveled through Shakur's chest, including through a lung. That caused his lung to collapse and bleed, and doctors ultimately removed the damaged lung in an effort to save his life, she said.

Additional bullets damaged his intestines and other parts of his body, she said.

Jurors looked intently at the photos of Shakur's body, which was bloated and had multiple chest wounds. The nearly full courtroom was quiet. One photo showed his tattoos and the chest tubes that were still in his body from the six days he spent in the hospital before dying.

The images were not shown in the video feed from the trial.

Gavin was not at Shakur's autopsy but was called as an expert witness because the examiner from 30 years ago has since died.

As Gavin explained the photos, Davis sat still, looking at the screen in front of him. He occasionally whispered in his attorney's ear.

Family members who had stepped out returned for the testimony of subsequent witnesses.

Akinyela said the photos made him feel "very angry, very angry, to say the least, very sad."

But he said, "I'm very spiritual, so just seeing the body doesn't affect me the same way as it might some people. I do believe that his spirit is still around and still lives on through his family and through his legacy."

Jury shown video of clash before Tupac Shakur's death

Prosecutors allege Shakur was killed to avenge his entourage attacking Davis' nephew, Orlando "Baby Lane" Anderson, a few hours earlier at the MGM Grand after a Mike Tyson fight.

On Tuesday, jurors were shown the casino's surveillance video of the clash. The camera, which panned back and forth in the MGM Grand, showed a group of people beating and kicking someone on the ground.

The video showed Shakur and his entourage moving quickly through the crowded building in the minutes after. At times, the other men had to jog to keep up with the rapper.

The surveillance footage then showed security and police arriving at the scene and talking to Anderson, who was wearing a number 13 Dan Marino Miami Dolphins jersey.

A few hours later, Shakur, riding in a black BMW with hip-hop mogul Marion "Suge" Knight, was gunned down by shots fired from a white Cadillac that had Davis, Anderson and two other men inside. Davis is not charged with pulling the trigger.

Knight has said he doesn't want to be called as a witness in the case, which could be a problem for prosecutors.

"It puts the prosecution in a really difficult position because it sounds like he's not going to be helpful for their case, and yet jurors are going to want to hear from the only living witness," CBS News legal contributor Caroline Polisi said.

"Hostile" witness refuses to revisit the past

After many technical and procedural witnesses, James McDonald brought both hostility and humor to the stand when he testified unwillingly under a court order.

McDonald, like Knight, had been affiliated with the Mob Piru Bloods gang and worked security for Knight at his Club 662, where Shakur and Knight had been headed when they were fired on. Davis was a member of the rival South Side Compton Crips.

Asked by Chief Deputy District Attorney Binu Palal if he was aware of why Anderson was beaten, he wouldn't say.

"I'm aware of a lot of things," McDonald said, "things that was going on, people ain't talked about them in 30 years. Today ain't one of them."

He said, "Me or anybody else bringing up the dead is wrong," and "you'd better treat me as a hostile witness."

McDonald said he wanted to avoid answering questions that would hurt Davis.

"Here I am explaining to people what I used to be. I'm not proud of that," McDonald said. "I don't want to send him to prison, even though we don't like each other."

He directly addressed the defendant at one point. "What you're going through, brother, is what you're going through," McDonald said, adding: "I didn't want to be a part of it." Davis had no visible reaction.

But McDonald also brought several moments of levity.

Asked if there were specific fights or disputes he could remember regarding the gang rivalry, McDonald said, "Are you serious?!" and laughter broke out in the courtroom.

Death Row security officer chronicles Bad Boy rivalry

Reggie Wright Jr., a former Compton police officer who owned a security company that was contracted by Knight's Death Row Records, detailed the way tension had grown between the label and Sean "Diddy" Combs' Bad Boy Records leading up to the Shakur shooting.

He said he had doubled Shakur's security guards after he released the video for "Hit 'Em Up," one of the most vicious diss tracks in the history of hip-hop, aimed at Bad Boy's Notorious B.I.G., who was killed six months later.

Wright said Shakur was to perform at Club 662 to fulfill required community service. He was on probation for California weapons and assault convictions.

After the shooting, Wright went to University Medical Center, where Shakur was taken, and said a crowd was gathering there. He called his father, who worked in the Compton Police Department's gang division, to tell him about the brawl and shooting, and warned him that trouble could be coming there.

Wright testified that he received Shakur's ashes after he was cremated, and saw that they got to Shakur's family.

Wright has long been among those rumored to be involved in Shakur's killing.

Palal asked him if he had anything to do with it.

"Absolutely not," Wright replied.

Shakur remains a cultural icon and is considered one of the most influential and versatile rappers of all time. He died as his popularity was peaking at age 25, and his legend has only grown in the years since.

His rap rival, the Notorious B.I.G., was killed six months later in a shooting that has always been paired with Shakur's in the public memory. 

That shooting has already been discussed at this trial and likely will be again. A former Los Angeles police detective testified that Davis was briefly a suspect in the shooting of the rapper born Christopher Wallace, but was ruled out. Tuesday's court day began with a recording of Davis talking to detectives about the Wallace shooting.
