According to TMZ, Dias' friend told authorities that he witnessed him taking what appeared to be LSD and mushrooms, before panicking and running into his room. The outlet also reports that Dias was found with lacerations on his forearm. However, police told ET that they were unable to confirm any reports of drug use being involved in Dias' death.

Dias is not the first former MTV star to meet a tragic end this year. In April, Clay Adler, who appeared in "Newport Harbor: The Real Orange County," died of an apparent suicide at age 27.
