Police investigators believe that fans of Jackass star Ryan Dunn may have unwittingly bought him drinks that contributed to his fatal car crash, RadarOnline.com can reveal.

Dunn and co-passenger Zachary Hartwell were killed instantly when the madcap actor lost control of his Porsche 911 at speeds of around 140mph while being twice over the legal limit.

West Chester State Police Liquor Control Enforcement Sgt. William La Torre now believes that fans gave Dunn drinks in a secluded area of an outside patio at Barnaby’s Of America bar in West Chester, Pennsylvania, before he got into his sports car.
