SALT LAKE CITY — An employee is suing his former boss over injuries sustained in an April 2009 drunken driving accident that killed one man and hospitalized four others.

Clifton R. Tolboe claims in the lawsuit filed this week that on April 1, 2009, John F. Bishop Jr. had consumed alcohol at his company-sponsored birthday party before driving five employees to a local strip club called Trails.

According to the lawsuit, Bishop left the club with the same five employees of Global Marketing Alliance in his company-owned car, driving at speeds up to 100 mph before colliding with another car on I-80 near 2400 East. Both vehicles slid out of control and crashed into a guardrail and bridge support before Bishop's vehicle eventually rolled.

Prosecutors charged Bishop with automobile homicide, a second-degree felony; four counts of DUI and causing serious bodily injury, all third-degree felonies; as well as other misdemeanor counts.

Jason L. Palmer, 26, of Salt Lake City, was ejected from the vehicle and killed.

Charges filed in 2009 state that Bishop fled the scene on foot and was later taken to a hospital where the four surviving passengers from the car were being treated for injuries.

Tolboe's lawsuit claims that Bishop was negligent in his actions. It also lists his employer, Global Marketing Alliance, and the company that owns GMA, Sovatphone Ouk, as being negligent, as well as the club Trails for allowing Bishop to leave while intoxicated.
