There's a series of high-profile criminal cases with hearings this week that could prove pivotal. Four of the cases have celebrity defendants or victims. The hearings and trials this week include a prosecution for the 1996 killing of rap icon Tupac Shakur and the murder case against singer D4vd. Also expected in court are attorneys for social media influencers Andrew and Tristan Tate, and the man accused of stabbing author Salman Rushdie. Some of the hearings could determine final resolution of the charges.
