Pink Taco founder Harry Morton died suddenly in November at just 38 years old. Now, the L.A. County Coroner's Office has released his official cause of death.
According to an autopsy report obtained by TMZ, Morton died from an irregular heartbeat, known as cardiac arrhythmia, due to hardening of the arteries.
There were no drugs or alcohol in his system, and Harry was reportedly preparing for a marathon.
The documents say that the morning he died, Harry had plans to go to the gym with his brother Matthew, but that he never showed. Matthew went to his house and found Harry on the bathroom floor. He was pronounced dead at the scene.
Family and friends gathered at his father Peter Morton's home in December. Guests included Lori Loughlin, Jimmy Iovine, Demi Moore and Stephen Dorff.
Peter co-founded Hard Rock Café and Hotel, and Harry's grandfather Arnie Morton founded Morton's The Steakhouse.
