Simon Monjack, the husband of late actress Brittany Murphy, was found dead Sunday night in his Hollywood Hills home, according to the Los Angeles Police Department. He was 39. The screenwriter was reportedly found by his mother-in-law, Sharon, in the master bedroom of the house he once shared with Murphy.

"The preliminary cause of death is natural causes," Sgt. Louie Lozano told the Associated Press. Another police spokesman, Sgt. Alex Ortiz, said, "We concluded there were no signs of foul play or any criminal activity involved."
