PHILADELPHIA (AP) – An appeals court has questioned whether Bill Cosby’s alleged history of intoxicating and sexually assaulting young women amounted to a “signature” crime pattern. The court on Tuesday cited studies that show as many as half of sexual assaults involve drugs or alcohol. The 83-year-old Cosby hopes to overturn his 2018 sex assault conviction because the judge let prosecutors call five other accusers to testify. The defense says their testimony prejudiced the jury against the actor and comedian. Cosby has spent more than two years at a state prison near Philadelphia. The jury convicted him of drugging and molesting a woman in 2004.
