Ryan Dunn PICTURED Before Fatal Crash
6/21/2011 2:41 AM PDT by TMZ Staff
Roughly two hours before "
Jackass" star
Ryan Dunn crashed his Porsche and died Monday morning ... he posed for pics with fans in a Philly-area bar ... glassy-eyed and flushed.
The pics show Ryan and his friends drinking at around 1 AM at a bar called Barnaby's of America in West Chester.
After downing at least 3 beers and 3 shots in 4-hours ...Ryan hit the road in his Porsche 911 GT3.
At around 2:38 AM, Ryan crashed -- killing himself and an unidentified passenger.
Officials later identified the passenger who was killed in the fatal crash as 30-year-old
Zachary Hartwell ... a friend who had been hanging with Dunn at a Philly-area bar earlier in the night.
Cops say both Dunn and Hartwell (
pictured above right) both died as a result of injuries sustained in the crash around 2:38 AM Monday morning.
Sources who were at the bar with the two men tell us Dunn had intended to drop Hartwell off at his home ... and then Dunn planned to hang out with another friend after that.
The Coroner's Office just released the autopsy results for both men -- who, we're told, were each dead by the time officials arrived at the scene.
Based on the autopsy results, the crash was so violent, it seems it was impossible to determine if the two died from the impact of the crash itself or from the fire that resulted.
Officials say the toxicology results for both men -- which would help determine the role alcohol played in the crash -- will be released in 4 to 6 weeks.
