Dunn, 34, and his 30-year-old friend Zachary Daniel Hartwell, died in a car accident in Pennsylvania early Monday. During the crash, Dunn's 2007 Porsche 911 GT3 went off a road, crashed into woods and caught fire.
Dunn and Hartwell were pronounced dead at the scene from blunt and thermal trauma when flames engulfed Dunn's Porsche.
Initial crash reconstruction probe revealed that Dunn's Porsche was travelling between 132 and 140 miles per hour at the time of collision and preliminary police investigation suggested that speed may have been a contributing factor to the accident.
Before his accident, Dunn reportedly arrived at Barnaby's of America in West Chester, Pennsylvania, around 10:30pm and had 2 Miller Lites and 3 girly shots over a four hour period till 2am.
The toxicology report indicated that Dunn's blood alcohol concentration (BAC) was 0.196 percent (w/v). BAC is most commonly used as a metric of alcohol intoxication for legal or medical purposes. For instance, a BAC of 0.10 means that 0.10 percent (one tenth of one percent) of one's blood is alcohol.
Going by this measurement, 0.196 percent of Dunn's blood contained alcohol, more than twice the legal limit of 0.08 percent.
However, the report found no evidence that Dunn had been under the influence of any drug.
No drugs of abuse detected, the report said adding that Dunn possessed a valid Pennsylvania driver's license at the time of collision.
Earlier reports suggested that the toxicology report may take at least 4 to 6 weeks of time. A fast-track toxicology report from the police may be attributed to the growing media attention to the case and Dunn's fan following.
Dunn had a massive fan following through Jackass, Viva la Bam, and Homewrecker shows, all of which showcased his penchant for peril.
Even after death, Dunn has been getting enormous amount of media publicity, thanks to legendary film critic Roger Ebert and Westboro Baptist Church (WBC).
It all began when Ebert tweeted Friends don't let Jackasses drink and drive, immediately after photos emerged showing Dunn drinking with his friends before the car crash.
However, he apologized for his remarks after severe backlash from twitter followers that even led to a brief outage of Ebert's Facebook account.
Now, it is WBC which is running after the corpse of Dunn, threatening to protest the funeral.
WBC will picket any public memorial/funeral held for Dunn, warning all not to make a mock of sin, & to fear & obey God the Church said in a statement, with headline stating: Ryan Dunn is in hell!
However, DellaVechia, Reilly, Smith & Boyd Funeral Home, Inc said services and interment for Dunn will be private, while a public memorial service will be announced at a later date.
Dunn, who was born in Medina, Ohio, moved to West Chester, Pennsylvania, in his early teens. Dunn was known for his dangerous antics and practical jokes in MTV's Jackass series and movies with his long-time friend Bam Margera.
He got to fame while appearing in videos alongside his friends in the Camp Kill Yourself (CKY) Crew.
The CKY videos caught the eye of Johnny Knoxville, a like-minded prankster who became the Jackass frontman. Knoxville asked to include CKY clips and new footage featuring them on Jackass, which had its premiere on MTV in 2000.
