Ryan Knight, star of “The Real World New Orleans” reality show, died from a deadly mixture of alcohol and several drugs, his final autopsy report revealed, according to TMZ. The 29-year-old was found dead on Thanksgiving Day 2014 by a friend.

Knight had various drugs in his system, including methadone, tramadol, cocaine and Xanax, which were mixed with a high level of alcohol, the Kenosha County medical examiner concluded, ruling that his death was caused by an accidental overdose, TMZ reported Wednesday. Knight reportedly died at his friend’s house in Kenosha, Wisconsin, after partying with him on Nov. 25.

Police reportedly said that they tried to revive Knight when they arrived at his friend’s home the following morning, but failed in their efforts. Police also said at the time that there were no signs of injury on Knight’s body and that there were no drugs found on the scene. In November, the Kenosha Police Department cited an autopsy on Knight stating that no “anatomical cause of death” was found, and that the reason behind his untimely death could be clear only from the results of the toxicology tests.

Knight was part of MTV's “The Real World New Orleans” in 2010, and later appeared on the spin-off series “The Challenge.” His death came just two weeks after Diem Brown, his co-star on “The Challenge,” died, aged 32, from cancer.
