Federal prosecutors began trying to prove Monday that Sean “Diddy” Combs turned his hip-hop conglomerate into a racketeering enterprise that forced women to satisfy his sexual desires for two decades. Testimony in Combs’ New York trial began Monday after a final phase of jury selection and opening statements from the lawyers. Combs has pleaded not guilty to charges including one count of racketeering conspiracy, two counts of sex trafficking by force, fraud or coercion, and two counts of transportation to engage in prostitution. Jurors were shown video surveillance footage of an attack by Combs on the singer Cassie, his then-girlfriend, at a Los Angeles hotel in March 2016 that prosecutors have maintained is a key piece of evidence in their case against him. The video depicts Cassie with a bag at the hotel’s elevators just before Combs rounds a corner, strikes her and throws her to the ground before kicking her and then dragging her back toward their hotel room. In all, prosecutors showed the jury two cellphone videos and three hotel surveillance videos related to the attack by Combs on Cassie at the Los Angeles hotel. Prosecutors were using the trial’s first witness, Israel Florez, a former security officer at a Los Angeles hotel, to introduce recordings of Combs beating Cassie at the hotel in March 2016. Florez said that when he responded to a call of woman in distress on the sixth floor of a Los Angeles hotel in March 2016, he came across Combs, wearing only a towel and sitting on a chair “slouched down, like with a blank stare ... like a devilish stare, just looking at me.” Combs shook his head slowly from side to side and the packed courtroom fell silent when jurors were shown the 2016 hotel security camera video for the first time. The video didn’t have sound. Jurors watched intently on video monitors at their seats in the jury box, but there were no discernible, visible reactions. Jurors ended up seeing the video four times. First prosecutors showed it all the way through. Then, they played it as the hotel’s assistant security director at the time, Israel Florez, described what was happening. Prosecutors then played a different version of the footage that Florez recorded off a monitor with his iPhone. Combs’ lawyer then showed it again as she sought to poke holes in Florez’s recollection of events. After Florez got straight to the allegations of violence by Combs, the second prosecution witness, Daniel Phillip, took the trial to the allegations of sex parties. Phillip said he was a male stripper for women when he was called by Cassie to meet her and Combs at the Gramercy Park Hotel in New York in 2012. Phillip said he was paid a few thousand dollars for the encounter in which Combs was wearing a white robe and watching as Phillip had sex with Cassie. Phillip testified that Combs subsequently hired him on several occasions for a redo of the same experience. The trial is to resume at 9:30 a.m. EDT on Tuesday. Phillip is set to return to the stand.
