Ryan Dunn, who starred in the ‘Jackass’ series of movies alongside Bam Margera and Johnny Knoxville, has died in an early morning car crash. Dunn and a passenger were killed when the Porsche 911 GT3 they were driving flipped over a guard rail and burst into flames just after 2:30 am. The passenger has not yet been identified. Police say speed may have been a factor in the crash, but it’s unclear if alcohol was involved. The last photo posted to Dunn’s Twitter account showed him drinking what may have been an alcoholic beverage. Dunn was 34.
