"B.I.G.'s murder took place on the last day that he and Combs were to spend in Los Angeles. B.I.G. and Combs did not decide until that afternoon to attend the evening's Vibe magazine party at the Petersen Automotive Museum in L.A.'s Miracle Mile District. The party would be a closed event for music-industry executives, Combs had been told; security would not be a problem. The scene at the Petersen Museum apparently had been quite mellow, especially given the complications suggested by the guest list. Among the women in attendance, for example, was B.I.G.'s estranged wife, Faith Evans, whom Shakur, on his last record, had famously claimed to have "fucked" as a way of settling scores with her husband.
Death Row rapper DJ Quik had shown up with ten fearsome-looking Treetop Piru Bloods in tow, while the dozen or so Crips who wangled invitations included Orlando Anderson, widely believed to have pulled the trigger on Shakur. By midnight, the museum was crammed with many more people than it was permitted to contain, and a majority were smoking marijuana. At 12:30 a.m., the air was so thick with smoke that an announcer warned the crowd, "The fire marshal's gonna turn the party out!""
