A man suspected of driving drunk and running away from a fiery fatal crash was charged Tuesday with automobile homicide and four other felonies.

John Featherstone Bishop, Jr., 35, allegedly was drunk around 8:45 p.m. on April 1, as he sped eastbound along Interstate 80 near 2400 East in his 2009 BMW. He rear-ended a Mercedes-Benz SUV and rolled his car.

"Witnesses estimated the speed of the BMW to be over 100 mph, in a construction zone, with a posted speed limit of 55 mph," according to the charges filed Tuesday in 3rd District Court.

The wreck injured a man and woman in the SUV. One suffered a crushed vertebra and broken vertebrae and the other suffered a concussion, broken ribs and whiplash.

Bishop was able to climb out of the wrecked BMW. Four of his five passengers had to be pulled from the burning car. The fifth, Jason L. Palmer, 26, of Salt Lake City, was thrown from the back seat of Bishop's car and killed. Troopers believe he was not wearing a seat belt.

Bishop ran from the scene and called for a ride from a nearby neighborhood. He showed up at Intermountain Medical Center, where he was treated for injuries that he claimed he suffered in an assault. His blood alcohol level at the hospital was 0.13, according to charges, and he had been drinking at a party and club earlier that night.

Bishop was allowed to return home, but he later was arrested for violating terms of his probation by drinking and driving. Bishop had pleaded guilty in connection with a March 2008 DUI accident and was on probation for that incident. He was booked into Salt Lake County jail on April 14 in lieu of $250,000 cash-only bail.

But Bishop now faces a slew of new charges: a second-degree felony for automobile homicide; four third-degree felony counts of driving under the influence of alcohol and causing serious bodily injury; two class A misdemeanors for driving under the influence and causing bodily injury; one class A misdemeanor count of leaving the scene of an accident involving injury; one class B misdemeanor count of reckless driving; and a class B misdemeanor count for violating his terms as an alcohol restricted driver.

If convicted of the most serious charge -- auto homicide -- Bishop faces a possible sentence of one to 15 years in prison, according to the Salt Lake County District Attorney's Office.
