Preliminary autopsy results say a ship captain on the Discovery Channel television program "Deadliest Catch" who died in Sturgis, S.D., during its famous motorcycle rally had a heart attack.

Meade County Sheriff Ron Merwin says an autopsy was completed Monday, but he's still waiting on a toxicology report for 50-year-old Tony Lara, a native of Alaska.

The sheriff says he doesn't suspect the toxicology results will show anything that would have contributed to Lara's death.

Lara died early Saturday morning at a private residence in Sturgis.

A post on the Discovery website describes Lara as a veteran crab catcher. He appeared on the show at the helm of a boat called the Cornelia Marie.
