Jay-Z says a rape allegation made against him is part of an extortion attempt. A woman who previously sued Sean “Diddy” Combs, alleging she was raped at an awards show after-party in 2000 when she was 13, amended the lawsuit Sunday to include a new allegation that Jay-Z was also at the party and participated in the sexual assault. The 24-time Grammy award winning rapper, producer and music mogul called the allegations “idiotic” and “heinous in nature” in a statement released by Roc Nation, one of his companies. He also revealed that he had anonymously sued the woman’s lawyer, Tony Buzbee, last month, alleging he was trying to blackmail the rapper by threatening to make the rape allegation public if he didn’t agree to a legal settlement. He said Buzbee sent a letter to his lawyer appearing to seek a settlement, but that the letter had the “opposite effect” on him. Mangione was charged Monday night with second-degree murder in the killing of 50-year-old Thompson. Investigators suspect that Mangione held a grudge against the medical insurance agency and may have been inspired by Ted Kaczynski, the mathematician-turn-domestic terrorist known as the "Unabomber" who blamed technology for a decline of individual freedom and mailed handcrafted explosives to targeted individuals between 1978 and 1995.
