Sean “Diddy” Combs’s sex trafficking trial starts with opening statements in a high-profile case that will not be publicly broadcast. Here are the key players.

Combs, who is charged with one count of racketeering conspiracy, one count of sex trafficking by force and one count of transportation for the purposes of prostitution, could face life behind bars if convicted.

Cassie Ventura, the former girlfriend of Sean “Diddy” Combs and one of his accusers, could take the stand as early as Monday as one of the first three witnesses called in the government’s sex-trafficking case against the music mogul.
