The Mohave County, Ariz., sheriff's office said Thursday that an autopsy showed 22-year-old Carl Otto Nathaniel Holm had a blood alcohol level of nearly .19 percent. That's more than twice the legal limit in Arizona.
The five were speeding in a Chevrolet Suburban when Holm failed to negotiate a turn on a dirt road.
Two teenage boys and two teen girls also died in the crash. They were from Colorado City and Cane Beds, Ariz., and Apple Valley, Utah. An 18-year-old Colorado City woman survived.
Sheriff's officials say the five may have been out celebrating a birthday when the crash happened.
