KINGMAN - The wrong-way driver involved in a violent collision on U.S. 93 that sent several people to the hospital Saturday night might have been under the influence of alcohol, according to the Kingman Police Department.

Roger Vanwormer, 45, of Kingman was reportedly driving south in the northbound lanes over Coyote Pass - between mileposts 68 and 69 - just after 10 p.m.

Vanwormer, the sole occupant of a blue-in-color 2005 Chevrolet Sedan, crashed into a maroon 2000 Saturn sedan that was driven by Todd Gronskei. Gronskei, 49, and his passengers, a 28-year-old woman, a 30-year-old man and a 3-year-old toddler, are all from Kingman.

While all five people were initially taken to Kingman Regional Medical Center, Gronskei and the woman were ultimately taken to University Medical Center in Las Vegas in serious but stable condition.

The man and the boy, who were in the backseat with the child in a car seat, were taken to KRMC with non-life-threatening injuries.

Firefighter-paramedics from the Golden Valley and Kingman fire departments used tools to cut out Vanwormer and the four occupants of the Saturn. Vanwormer's vehicle landed on its roof. Both sedans were totaled in the wreck.

Vanwormer also sustained non-life-threatening injuries and was taken to Kingman Regional Medical Center. Kingman Police spokeswoman Jennifer Sochocki said the investigation remains open and nobody has been cited. She said KPD investigators believe Vanwormer might have been drinking alcohol.

The Arizona Department of Public Safety crime lab will analyze Vanwormer's blood to determine if he had been drinking and, if so, if he was over the legal limit.
