The 34-year-old's 'Jackass' cast-mates Johnny Knoxville, Bam Margera and Steve-O are yet to comment on the tragic accident, but Acuna took to his Twitter page this afternoon to pay tribute to his close friend, saying, "Ryan Dunn- a super awesome memory was at the J Rody walston & the business show!!! I Miss You Bud!! You were always a happy kick-ass dude!!" Dunn, who starred in all five Jackass movies, died in the automobile crash at around 2.38am. Just hours before the incident he had posted an image of himself drinking with two friends on Twitter. It is not clear whether either of the two individuals were in the car at the time of the crash, but reports suggest there was at least one other fatality.
