The autopsy of a man whose friends allegedly drove his body around the metro area found he had drugs and alcohol in his system.The Denver County coroner on Friday ruled Jeffrey Jarrett's death an accident and said Jarrett's cause of death was mixed drug intoxication.In the autopsy report obtained by 7NEWS, the coroner said Jarrett had alcohol, cocaine, alprazolam and buprenorphine in his system.While cocaine is an illegal drug, alprazolam and buprenorphine are prescription drugs.Alprazolam is a drug used to treat anxiety and panic disorders, and buprenorphine is used to treat addiction to narcotic painkillers, according to the U.S. National Library of Medicine.According to the police report obtained by 7NEWS, Robert Young went to Jarrett's home and found him unresponsive. But rather than call the authorities, Young went to find another friend, Mark Rubinson, and told him that something was wrong with their friend, police said."In my mind, I wanted to believe he was passed out. I didn't want to call 911," Young said Thursday. "I didn't want to believe he was dead."Young and Rubinson went to Jarrett's home and put him into Rubinson's SUV and headed to a nightspot where they spent more than an hour drinking, leaving Jarrett's body in the vehicle, according to police records.Jarrett's body remained in the back seat while the pair drank and ate at Teddy T's bar and grill and Sam's No. 3, the affidavit said. They used Jarrett's credit card to pay for the drinks, police said, noting "they did not have Jarrett's consent."Young said he realized Jarrett was dead while leaving the bar and the two men took him back to his home after notifying police. They then went to 7-Eleven, Viva Burrito and Shotgun Willie's strip club, where Young withdrew $400 from an ATM and stayed until closing time, according to the affidavit.Young said Jarrett owed him money and gave him his credit card.Young rejected comparisons to the plot of the 1989 movie "Weekend at Bernie's," in which two men try to pass off their deceased boss as alive. He said the ordeal only lasted four hours, and insisted there was no resemblance to the movie."It's not a joking matter. He deserves better than that," Young said.Young and Rubinson were arrested on suspicion of identity theft and abuse of a corpse. They are not charged in Jarrett's death.An arrest warrant was issued on Tuesday for Rubinson for failing to appear at a hearing. Rubinson said someone stole his car so he couldn't make the court appearance. He was taken into custody on Wednesday.
