Clatsop County Sheriff Tom Bergin told the AP that Painter's body was discovered May 25 by a friend who became alarmed when he couldn't reach him.
According to E! news, no cause of death has been given.
No foul play is expected, TMZ reports. Prescription pills were also at the home, but it is unclear if they played a role in his death. The Discovery Channel series "The Deadliest Catch" followed the Maverick and its crew fishing for crab in Alaskan waters.
Our thoughts are with Painter's loved ones during this time of mourning.
The local newspaper, The Daily Astorian, reported in January that Painter was arrested by Astoria police after an officer allegedly saw Painter smoking heroin while driving.
Painter, an OR native, featured in the second and third seasons of Deadliest Catch, now in its 14th season. He was charged with DUI, heroin possession and evidence-tampering. He first popped up during season 2 in 2006, but chose to depart the show a few episodes into season 3. He eventually quit the show after appearing on its third season, according to reports.
Deadliest Catch has been on air since 2005 and its 14th season premiered in April this year.
