LOS ANGELES - Jonas Bevacqua, who co-founded the popular street clothing brand LRG in 1999 and presided over its rapid rise as a major fashion force among young people, was found dead yesterday. He was 34.

Orange County sheriff's officials said that Bevacqua's body was found in his Laguna Beach home.

An autopsy was slated for today.

Calls to LRG's headquarters in Irvine rang unanswered.

According to the company's Facebook page, Bevacqua and his business partner, Robert Wright, founded Lifted Research Group, known to patrons as LRG, with start-up capital raised in part from friends of Bevacqua's adoptive father.

By 2006, LRG had annual sales of $150 million and was named by Entrepreneur magazine as No. 5 on its list of that year's 500 fastest growing companies.

Among its popular clothing lines are Luxirie, which targets 18- to 30-year-old women, offering clothing with Western and military themes, and items such as crystal-covered jeans.
