WAUKESHA COUNTY, WI (WTAQ) - A suburban Milwaukee teenager is due back in court Tuesday, after he allegedly slammed into a Waukesha County patrol car while driving drunk on Interstate 94.

The defendant’s vehicle burst into flames upon impact – and his passenger was killed.

18-year-old Ihor Sahan of St. Francis is being held on a $100,000 bond on a charge of drunken homicide and two counts of causing injury while under the influence.

Authorities said Sahan’s blood alcohol level was 0.135 when he lost control on the Interstate near Brookfield early last Thursday. Officials said the vehicle was speeding at 74 miles an hour when it slammed into a patrol car in the median in which two sheriff’s deputies were watching for speeders.

The deputies suffered non-life-threatening injuries, but were able to pull the two teens from their burning car.

Sahan’s passenger, 17-year-old Ryan Petri, died Saturday, two days after the crash. 

Sahan suffered minor injuries. He told officers they were returning home from a concert in Madison where he had six vodka and Gatorade drinks in a one-hour stretch.
