Five months after actress [article id="1628612"]Brittany Murphy was found dead[/article] in her Los Angeles home, the late actresses' husband, Simon Monjack was discovered dead in the same house on Sunday night.

The Los Angeles Times reports that British screenwriter Monjack, 39, was found dead of yet-unknown causes at the home he shared with Murphy, who died in December at age 32 from what a coroner determined was a combination of pneumonia, anemia and multiple drug intoxication.

The Los Angeles Fire Department responded to a 911 call at 9:24 p.m. on Sunday for an "unspecified medical aid request," according to a fire department spokesman. After Fire Department personnel attempted to provide medical assistance to Monjack, he was pronounced dead at the scene.

TMZ reported that Murphy's mother, Sharon, who also discovered her daughter's body, was the person who found Monjack unconscious in the master bedroom and it was she who called 911 to report the medical emergency.

The site claimed that Monjack reportedly died as a result of cardiac arrest, though that has not been confirmed. A death investigation is under way. Following Murphy's death, Monjack said in an interview that he suffered from seizures and had suffered a heart attack while returning from a vacation in Puerto Rico in 2009.

Monjack was born in Hillingdon, England, on August 5, 1970, and is best known for writing and directing the little-seen 2000 movie "Two Days, Nine Lives."

In February, a coroner's report dispelled rumors that [article id="1632707"]Murphy had died[/article] as a result of illegal drug abuse or excessive alcohol intake. A death investigation determined that the pattern of the elevated levels of drugs in her blood "suggest treatment of symptoms of a cold or other respiratory infection." The report found "no history of alcohol or drug abuse" and Murphy's body was "normally muscular and slim but not excessively thin."
