The self-proclaimed “King of Infomercials” Don Lapre, 47, was found dead in his cell of an apparent suicide on Sunday, although an investigation is still underway. Lapre was jailed in an Arizona federal jail without bond on charges of defrauding at least 220,000 people out of nearly $52 million. Under the company name “The Greatest Vitamin in the World,” Lapre sold vitamins that the FDA said failed to live up to advertising claims, leading to an indictment on 41 counts of conspiracy, mail fraud, wire fraud and promotional money laundering.

His trial was to begin on Tuesday.

Take a look at one of Lapre’s infamous TV ads, as well as a news story about his death.
