His devastated castmate Steve-O, who has long battled drink and drug addiction, has now spoken out about the dangers of alcohol following public criticism of the friends who allowed Dunn to drive home drunk.
He tells BBC Radio 5 Live, "If people are upset about drink-driving, I think there's some validity in that... I'm not going to be wounded or offended by people speaking out against drunk-driving. My only position in this is that I lost a friend, and I'm not defending drunk-driving. We were all a very close family, and here we've lost a brother. We've devastated by this."
