Mark Balelo, an auction house owner who made numerous appearances on A&E's Storage Wars, was found dead Monday morning after an apparent suicide attempt. He was 40.

Balelo was found in his car with the motor running, parked in the garage of his auction house in Simi Valley, Calif., according to a TMZ report. It was an employee who found him Monday morning.

Balelo had been arrested on Saturday for possession of a controlled substance. He was scheduled to appear in court on Feb. 19. He was reportedly visited by his fiance over the weekend after he had requested to see her.

Jokingly known as Rico Suave, for his taste in clothing, Balelo had made the news in 2011 when he helped Nicholas Cage, 49, recover an extremely rare Superman comic book that he reported stolen 10 years earlier. The comic book featured the first appearance of Superman.

Baleo's official cause of death is still under investigation by authorities.
