The still-unsolved 1996 murder of rapper Tupac will be the focus of a segment of National Geographic Channel’s forthcoming The ’90s: The Last Great Decade? documentary, according to Rolling Stone

The three-night, six-hour documentary is slated to air in two-hour blocks July 6-8 starting at 9 pm EST each night.

The Tupac portion of the program features commentary from “2 Of Amerikaz Most Wanted” video director Gobi Rahimi, who was with Tupac the night he died in a Las Vegas hospital.

After Tupac was shot, Rahimi says that he and the Outlawz took turns watching over the wounded rapper. “I think they had weapons in their car,” Rahimi says, “because the whole time we were there, we were fearful [whoever shot Tupac] was gonna come finish him off.”

Outlawz member E.D.I Mean says there’s a reason why Tupac’s murder remains unsolved. 

“Law enforcement around the country weren’t big Tupac fans,” he said. “I’m absolutely positive they know what happened. This is America. We found Bin Laden.”
