Police Officer Rosario Herrera says Wittels' assistant found him at his home in the Los Feliz area around noon Thursday, and he was pronounced dead at the scene.

Herrera says the death is being investigated as a possible drug overdose but the Los Angeles County coroner's office will determine the exact cause.

TMZ reported that drug paraphernalia was found in Wittels' home. The comedian had been open about his past drug use, according to ETOnline.com.
