Another mysterious death has got the Internets buzzing. Over the weekend, Josh Greenberg, the co-founder of the controversial music streaming service Grooveshark, was found dead in his apartment. The cause of death of the 28-year-old Florida resident has yet to be determined, according to police. Find out the details after the jump!

Last Sunday (July 19), Grooveshark co-founder Josh Greenberg was found dead by his girlfriend in his apartment in Gainesville. He was 28. His girlfriend, Abby Mayer, was away for the weekend when she came home and found Greenberg dead in his bed. According to police, there were no drugs found nor were there any obvious signs of foul play.

Mayer claims he “had never been sick a day in his life” and was not prescribed any medications. His mother, Lori Greenberg, said that the autopsy report did not surface anything out of the ordinary. “They are as baffled as I am,” she said to the Gainesville Sun.

As a 19-year-old freshmen at the University of Florida, Greenberg and fellow founder Sam Tarantino, had created their music streaming service Grooveshark in March 2006. Over the years, the service had garnered 40 million users a month with 145 employees who worked from the Union Street Station in downtown Gainesville as well as a small office in New York City.

However, Grooveshark was eventually sued by several record companies over copyright violations. After the legal battle ended back in April of this year, Grooveshark officially folded. According to his mother, Greenberg was more relived than depressed that the company shut down. The official toxicology report from Greenberg’s autopsy will be ready for review in three months.
