It has now emerged that Dunn and his passenger, Zachary Hartwell, were killed from the blunt force trauma of the crash, with the fire that engulfed the vehicle following the accident also contributing to their deaths.
TMZ also reports that the 34-year old and Hartwell were dead when police arrived at the scene.
According to the Guardian, a preliminary examination of the accident site stated that Ryan could have been speeding, driving the Porsche at over 100mph in a 55mph zone, before losing control and crashing into a tree.
Following reports that Dunn could have been over the legal drink-drive limit, toxicology results will be revealed in the next four to six weeks.
Ryan's brother, Eric Dunn, has since released a statement regarding his sibling's death, telling AP that his family are "devastated" before adding: "We appreciate the support of Ryan's fans during this time, and we are grateful for your thoughts and prayers. Ryan will be greatly missed, but he will forever remain in our hearts."
Dunn's Jackass co-stars paid homage to their pal on Twitter following his death, with Bam Margera even visiting the crash site, breaking down into tears.
