William John Antoniewicz

Trooper Antoniewicz was shot during a traffic stop on I-80 near Echo Junction.

While approaching the vehicle, the suspect shot him several times with a .38-caliber handgun. The man then kicked Trooper Antoniewicz in the face several times before fleeing. The suspect was apprehended 18 months later. The first trial resulted in a hung jury and the man pled guilty to a reduced charged of second-degree murder in order to avoid a second trial. He was released after serving 12 years of a 15-year sentence.

Trooper Antoniewicz had been with the agency for five months.

I was working for Webwe County Sheriff at the time , this was one of the coldest nights of my life. We had a road block at the mouth of Weber Canyon all night long. Memories of that night remained a constant reminder on every traffic stop I made for the next 31 years.
