Tony Lara, who was featured on Discovery’s Deadliest Catch, died on Saturday in South Dakota, PEOPLE can confirm.

“Our thoughts and prayers are with his family at this sad time,” a spokesperson for Discovery tells PEOPLE.

Lara, 50, was in Sturgis, South Dakota, for its annual motorcycle rally when he died over the weekend in a private home.

On Tuesday, Meade County Sheriff Ron Merwin told PEOPLE that after an early autopsy Lara is believed to have died from a heart attack in his sleep.

“It appears to be a heart attack. As far as alcohol and drugs the toxicology report will not be back for a few weeks,” he said.

Merwin added: “As far as I know the body has been released to family and arrangements will be made to get him wherever they wish. I assume Alaska.”

Lara’s death comes less than a month after Joe McMahon, a producer on Deadliest Catch, was shot steps from his home in Pasadena, California.
