Harry Morton, a prominent restaurant founder and former club owner, was found dead Saturday at 38.

Mr. Morton, whose Pink Taco chain is a staple in the western United States, was found unresponsive at his home in Beverly Hills, TMZ and People reported.

The restaurant mogul had heart disease and suffered "sudden cardiac death," his family says.

Los Angeles County coroner Matthew Miller "confirmed to the Morton family that Harry Morton had coronary artery disease with a mildly enlarged heart," the family said in a statement sent to the Daily News.

The statement said family friend Kathy Magliato, a heart surgeon, also reported Mr. Morton "had calcification in three main arteries and suffered sudden cardiac death — an unexpected death caused by loss of heart function."

He was found unresponsive by his younger brother, Matthew, People reported, citing a source. The Beverly Hills Police Department confirmed Mr. Morton's death to the magazine.

Mr. Morton showed no warning signs before his passing, a source close to the family told The News Tuesday night.

"He was healthy. No drug use," the source said.

"It's been a shock to the family. He ran marathons and loved to go fishing," the source said.

In a statement to TMZ, a rep for Pink Taco said the company is "saddened" by Mr. Morton's death.

"Harry was a visionary and restaurateur ahead of his time, and his contributions, both professionally to our brand and personally to those he worked with, were numerous," the spokesman said. "Our thoughts and condolences are with his family and friends during this difficult time."

Mr. Morton came from a family of restaurateurs. His grandfather, Arnie Morton, founded the Morton's Steakhouse chain, while his father, Peter Morton, is a co-founder of Hard Rock Cafe.

"We are devastated by the loss of our beloved son, brother, and friend. Harry was the brightest light in all our lives and his spirit will live on forever," the family said in the Tuesday statement.

Harry was 18 when he started Pink Taco in 1999. He also notably bought the Viper Room club in Hollywood in 2008, 15 years after actor River Phoenix suffered a drug overdose outside the venue and tragically died at 23.

He garnered attention for his personal life as well, as he was rumored to be romantically involved with stars such as Paris Hilton, Lindsay Lohan, Demi Moore, Britney Spears and others over the years.

"Best friends. Best life," Ms. Lohan wrote a caption to a black-and-white photo the pair she posted on Instagram Sunday.
