Harry Morton's family says that the restauranteur died of a heart attack, though the Los Angeles County Coroner’s Office still yet to confirm his official cause of death.
Harry, who died suddenly over the weekend at age 38, was suffering from a coronary artery disease — which is a narrowing or blockage of the coronary arteries — and a "mildly enlarged heart," his family spokesperson said in a statement to multiple outlets.
The family added in their statement that family friend and heart surgeon Dr. Kathy Magliato found that Morton "had calcification in three main arteries and suffered sudden cardiac death — an unexpected death caused by loss of heart function."
The coroner’s office previously told PEOPLE that though an autopsy was completed on Monday, Harry's cause of death had officially been deferred pending additional investigation. The coroner's office did not immediately respond to PEOPLE's request for comment on Tuesday.
Authorities said that there was no evidence of foul play in Harry's death. A source added that Morton's younger brother, Matthew, was the one who found the business owner unresponsive in his Beverly Hills home on Saturday.
Harry, perhaps best known for founding the trendy Pink Taco chain, comes from a long line of restaurant owners.
