Hedge fund manager Sanjay Valvani, charged last week in one of the most significant insider-trading prosecutions in recent months, was found dead in his home the evening of June 20, an apparent suicide, authorities said.

Valvani, 44 years old, was found by his wife in the bedroom of their Brooklyn home with a slash wound to his neck, said a New York Police Department spokesman. He was pronounced dead around 6:30 p.m.
