"Jackass" star Ryan Dunn's death in a fiery crash when his Porsche ran into a forested area at high speed raised questions as to whether alcohol was involved. Though the toxicology results may not be released for weeks, Dunn apparently tweeted a photo of himself having a beer with friends shortly before he and passenger Zachary Hartwell died. Film critic Roger Ebert soon tweeted, "Friends don't let jackasses drink and drive," which drew nasty responses from fans and friends.

Toxicology results will take four to six weeks to complete, coroner's office spokeswoman Patty Emmons said. Dunn, 34, and passenger Zachary Hartwell died early on Monday, shortly after leaving Barnaby's, a pub in West Chester, Pennsylvania. Dunn had tweeted a photo of the pair and a third man drinking just hours before the crash, but the photo has since been taken down.

The manager of Barnaby's, Jim O'Brien, told the Philadelphia Inquirer that Dunn was drinking with several friends at the bar but didn't appear drunk.

A preliminary examination of the crash site suggested Dunn's Porsche may have been travelling more than 100mph (160kph) in the 55mph zone when it jumped a guard rail, flew into a wooded ravine, struck a tree and burst into flames.
