"It has never been proven that Christopher Wallace was not in Las Vegas on the night Tupac was shot," Philips wrote in response to a reader's question. "Bad Boy produced some computer-generated documents purporting to place him in a recording studio in New York, but they were not time-stamped. Bad Boy said it was going to produce video of Biggie there. They never did that. I have since learned that federal officials conducted interviews in Las Vegas to determine whether Wallace was present. My sources were there and say he and other East Coast figures were in Las Vegas on the night the Southside Crips killed Tupac."
