Murder charges have been filed in the death of a Buffalo Grove woman who was shot on a Wisconsin highway Sunday as her family returned from Wisconsin Dells.

20-year-old Zachary Hays has been charged with one count of first degree homicide and three counts of first degree recklessly endangering safety, authorities in Wisconsin announced today.

44-year-old Tracy Czaczkowski was shot Sunday on Interstate 90-94 near mile marker 95 around 3 p.m. Sunday near Deforest, Wisconsin. Police say Tracy’s 43-year-old husband was driving her and their two children eastbound on I-90/94 back to their Buffalo Grove home from the Wisconsin Dells area.

Their vehicle was passing a Chevrolet Blazer allegedly driven by Hays. Hays allegedly fired a gun at the Czaczkowski’s vehicle, striking Tracy in the neck.  She died at the hospital.

According to a statement from U.S. Drug Enforcement Agency, Tracy’s husband has worked for the DEA for 11 years.

Tracy’s husband and children were not injured in the shooting.

Police arrested Hays Sunday after detaining the Blazer.  Hays exited the vehicle and approached police armed with a hand gun.

“Despite verbal commands to stop, the suspect continued to advance toward law enforcement and two Columbia County deputies shot the suspect,” officials said in a statement.

Authorities say Hays also allegedly shot and killed a 42-year-old man in his Wisconsin apartment building earlier Sunday.
