Brittany Murphy's widower Simon Monjack has been found dead in the Los Angeles home he once shared with the actress.
 
Murphy's mom Sharon is said to have called emergency services on Sunday night after finding the screenwriter unconscious in the master bedroom of the Hollywood Hills property where the Clueless star died in December. He is believed to have suffered a cardiac arrest. Resuscitation efforts failed and he was pronounced dead at the scene, according to ETOnline.com.

Sergeant Louie Lozano of the Los Angeles Police Department (LAPD) tells the website, "We have detectives at (the) scene. They are conducting their investigation."

The L.A. coroner ruled in February that Murphy died after from pneumonia, complicated by anemia and multiple drug intoxication.

She is said to have gone into cardiac arrest at the house she shared with Monjack and Sharon, and was pronounced dead at Cedars-Sinai Medical Center in Los Angeles on December 20th.
