Stephen Monjack has followed the footsteps of his late wife a mere five months after her death. Doctors believe he died of a heart attack at his home. 

Sky News reports: "LA's fire department had responded to an emergency call for an 'unspecified medical aid request' at the property on Sunday, according to force spokesman Brian Humphrey. Mr Monjack was later pronounced dead, police sources said. Murphy died of pneumonia complicated by an iron deficiency, anaemia and multiple drug intoxication on December 20. Coroner's officials said Murphy had gone into sudden cardiac arrest because of 'drug intake'. Her death was classified as an accident."

Meanwhile, TMZ reports: "Law enforcement sources say Brittany's mother, Sharon (who also found Brittany), found Monjack unconscious in the master bedroom around 9:30PM, and then called 911. Monjack was pronounced dead sometime after paramedics arrived."

The 39-year-old claimed after his wife's death: "I suffer from seizures. I had a heart attack coming back from Puerto Rico last year."
