An 18-year-old Mequon man faces charges of homicide by intoxicated use of a vehicle, and OWI (1st with passenger under 16 years old) in connection with a fatal crash that happened in Mequon early Sunday, July 2.

While in a police squad, an officer "could smell the overwhelming odor of intoxicants coming from his person. Benske made a statement that his little brother had been drinking and that they had switched who was driving before the crash" the complaint says.

At the crash scene, officers spotted a red SUV with major front-end damage and all interior airbags deployed. The complaint says there "were tire marks on the roadway that indicated that the (SUV) had failed to negotiate a curve in the roadway, and it appeared the vehicle had overcorrected and then gone into the west ditch where it struck a tree."

Benske was taken to the hospital for treatment of minor injuries.
