A former star of MTV's Road Rules reality show has been found dead, the New York Daily News reports. Sources tell TMZ a friend was with Danny Dias at his Brooklyn apartment Saturday when he saw Dias take what he believes was LSD and mushrooms, start "freaking out," and run into his room. The friend never saw him again and eventually left the apartment, getting no response when he called Dias over the next two days. He called 911 on Monday and first responders found Dias, who appeared on the 2004 season of the reality series and on MTV's The Challenge the following year, dead in his room. "Police discovered a 34-year-old male unconscious and unresponsive," an NYPD rep tells Us Weekly (some sources are reporting Dias was 33). Cops, who note he was found with two vertical slices on his forearm—"a common sign of suicide," per TMZ—continue to investigate. (More celebrity death stories.)
