Late actress Brittany Murphy's husband Simon Monjack has been found dead at his Hollywood Hills home.
According to the Los Angeles Police Department, the 39-year-old screenwriter was found unconscious by Murphy's mother Sharon, in the master bedroom of the home he once shared with his wife.
Murphy, his wife of less than three years, died five months ago.
Paramedics were called to the scene by Sharon just before 9.30pm on Sunday (local time). He was pronounced dead by paramedics after resuscitation attempts failed.
Police spokesman Sergeant Louie Lozano said there were no signs of foul play, and that the preliminary cause of death was natural causes. He is believed to have suffered a heart attack.
Lozano said: "We have detectives at scene. They are conducting their investigation. Once we have further information, we will provide it."
However, reports have also emerged suggesting Monjack may have died of an accidental drug overdose. Officials have confirmed prescription medication was found at his home.
A source tells TMZ: "There were a number of pill bottles on the nightstand in the bedroom, and some were empty."
LA County Assistant Chief Coroner Ed Winter said: "This evening, Mr Monjack was found unresponsive, paramedics responded to the house, he was pronounced dead at [9.45pm on Sunday].
"There were some prescription drugs found that belonged to Mr Monjack, and we'll have an ongoing investigation," he added.
"Cause of death is pending, and there will be an autopsy after a day or so, and pending toxicology [reports,] we'll be releasing the results after we get all those tests back."

Heart problems
Monjack claimed to have a history of heart problems. He collapsed onboard a flight from Puerto Rico last November, and needed medical assistance. He later said he'd suffered a heart attack.
