The Sean “Diddy” Combs sex trafficking trial resumed Monday when singer Dawn Richard testified that the hip-hop mogul threatened to kill her if she told anyone that she saw him beat his longtime girlfriend. Richard told a jury in Manhattan federal court that Combs issued the threat the day after she witnessed the Bad Boy Records founder try to hit Casandra “Cassie” Ventura with a skillet and then beat her. Assistant U.S. Attorney Mitzi Steiner asked Richard what she took “we could go missing” to mean.
