Lara died on Saturday in Stugis, South Dakota
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.”
