MTV reality star Danny Dias has died at age 33. Diaz was found dead over the weekend in his Brooklyn, New York apartment at age 34, according to Us Weekly. Diaz was pronounced dead at the scene after a 911 call was placed after one of the former “Road Rules X-Treme” star’s friends became concerned after not being able to get a hold of him for several days. TMZ is now reporting that Diaz may have committed suicide after “freaking out” after taking LSD and mushrooms. The celebrity gossip site reported that Dias was found unconscious in his bedroom with lacerations on his forearm.

MTV stars say goodbye

Following the news of Dias’ death, several MTV reality show alums took to social media to pay their respects to their onetime co-star and franchise friend.

Brain Candy Podcast hosts Sarah Rice (a onetime “Challenge” winner) and Susie Meister (who was Dias’s “Real World/Road Rules Challenge: The Gauntlet 2 teammate), wrote that the late reality star was a friend of their reality TV family. “So sad to learn of Danny Dias' passing, a veteran of our reality family. Our thoughts are w/ his family,” the duo wrote on Twitter.

In addition, “Real World” and “Road Rules” veteran Beth Stolarczyk retweeted a story about the death of her former “Gauntlet” castmate. MTV has not yet commented on the death of Danny Dias.

Danny’s ‘challenging’ history with ‘Road Rules’

The following year, Dias competed on “The Real World/Road Rules Challenge: The Gauntlet 2.” Dias competed on the Rookie team alongside fellow MTV newbies Jamie Murray, Cara Zavaleta, and Jo Rhodes as they competed against franchise veterans like Marl Long, Julie Stoffer, Syrus Yarbrough Ruthie Alcaide. Danny Dias was eliminated from the competition in the fourth episode after clashing with teammate Jodi Weatherton and being pulled into the Gauntlet by Alton Williams, where he lost after badmouthing him.

After his reality TV career wrapped, Dias worked in finance and co-founded an AIDS research charity called Generation Cure.

Danny Dias is the third MTV reality alum to die this year. "Newport Beach" star Clay Adler committed suicide earlier this year and “Rob & Big" star Christopher Boykin died suddenly in May.
