After more than 13 hours of deliberation over three days, the New York jury found Combs not guilty on a RICO conspiracy charge, not guilty on a sex trafficking charge involving Cassie Ventura, and not guilty on a sex trafficking charge involving his ex-girlfriend "Jane," who testified under a pseudonym. He was convicted on two counts of transportation to engage in prostitution, then denied bond while he waits for his sentencing hearing. That hearing is scheduled for October but could move up. The prosecution is arguing he should be sentenced to around four and a half years, while the defense says the federal guidelines for his offenses put him closer to two years.

After two hours of instructions from Judge Subramanian -- including how to gauge the credibility of witnesses and a reminder to not google anything -- the jury began deliberating. Combs appeared less stressed than he did during closings. After the jury left, the judge closed the courtroom to give him some time with his children.

Defense attorney Marc Agnifilo argued that Cassie Ventura was the winner of her relationship with Combs. "She is sitting somewhere in the world with $30 million," he said. "He's in jail." And he tried to make the prosecution of Combs relatable. "They take yellow crime scene tape, figuratively, and they wrap it around his bedroom," he said. "The crime scene is your private sex life." In its rebuttal, the prosecution said the defense "just spent a whole lot of energy trying to blame his victims and the U.S. government for his lies, his threats, and his violence."
