As we all know, Real World and Challenge star Ryan Knight passed away in November of 2014.

Recently, an autopsy revealed that his death has been rules and accidental overdose resulting from a mixture of alcohol and numerous drugs including the prescription strength painkiller tramadol.  While Knight was known for being the life of the party, his struggle with drug addition was chronicled during his Real World season. Prior to appearing on The Real World, Knight hurt his shoulder while playing hockey and was required to have surgery. During the recovery he became dependent on painkillers and later had to overcome this addiction. While Knight appeared to have control over his addiction on The Real World and later Challenges, this is a sad reminder that drug addictions remain a daily battle.

While this discovery may answer some questions, Challenges fans remain saddened by the loss of Knight.
