Trooper William J. Antoniewicz

Died on December 8, 1974

Age 27
Utah Highway Patrol
Homicide: Handgun

Trooper Antoniewicz was shot and killed during a traffic stop in Echo Canyon. At approximately 10 p.m., the 27-year-old victim stopped a speeding vehicle eastbound on Interstate 80, nine miles east of Echo Junction. The driver shot Trooper Antoniewicz twice with a .38-calibre revolver, kicked him in the head, and then fled the scene. The victim’s body was discovered by a passing trucker. After an investigation lasting nearly two years, a suspect was charged with the murder. The trial ended in a hung jury. Rather than face a second trial, the suspect pled guilty to second-degree murder. After serving 12 years, he was paroled in 1989. Trooper Antoniewicz was single and had been a member of the UHP for six months. He was buried in Richmond City Cemetery. His bronze name plaque is sponsored by the Utah Highway Patrol Association.

    I was working for Weber County SO at the time and spent the entire night manning a road block at the mouth of Weber Canyon the night of this shooting. It was a long cold night. I spent the next 30 plus years in law enforcement working in three states. I have attended more memorial services for fallen officers, but none touched me like this one and that night. One of this country’s unsung heros.

    We were driving through the Canyon and stopped at the rest stop. Climbed the hill, and I saw this cross and took a picture. It took me a while to follow up, but this trooper’s cross moved me. It took me a while to follow up, but he deserves something more at that site. You give your lives, and he gave the ultimate sacrifice. I shared it on my Facebook page, but I am not sure that will ever be enough. He was a hero!

    12 years? You’ve got to be kidding.

    The date has to be wrong … it was the 2nd day of P.O.S.T. training that his seat was empty and we were told he’d been killed. That would have been November 4 or 5 1974.

    I’m a truck driver and I stop at Echo quite often. On a hill at the rest area someone built a memorial cross.
    It looks old and falling apart. Some other tried to fix it and today I did too. I left a coin and a pink quartz heart. Today I could put a face behind the fading name.
    Thanks Trooper, Rest In Peace

    The killer was out after 12 years. That’s wrong. He deserves better than a decrepit sodden cross and a murderer walking free. Shame on us!

    Because of the American Atheists, the large cross had to be moved.

    He was my uncle, the date indeed was Dec. 8, 1974

      I never knew this man , I would have only been a teenager at the time but I travel this Highway often and have seen his marker at MP 186 with the flag torn by the strong winds , I have stopped and replaced that flag now four times my self in the past two years for you Laura J Facer and the rest of his family just as respect to a man that seems to have been over looked by the state . >? not trying to set blame just wanted you to know he has another new flag up today :o)

        Thank you for looking out for our Fallen Officers. I will pass the flag issue on to folks who work on the crosses and flags.

      Kevin.. I just read your post from 2017. I am also sorry to hear about the death of your father. That is intriguing that your father was also from New Bedford and was killed just a short time later, so close to where my Uncle was killed. I wish you peace and hope you are well. Thank you for your comment.
