What Happened

Patrolman William P. Bosak and Patrolman Roger Van Schaik were shot and killed in an ambush attack near the intersection of 115th Street and May Street at 4:15 pm. They were returning to their squad car when a motorist traveling in the opposite direction stopped alongside them and opened fire with an M-1 rifle without warning. The killer was apprehended, convicted of the murder, and sentenced to death. On January 10th, 2003, outgoing Governor George Ryan commuted the death sentences of all 167 Illinois death-row inmates, including the death sentence of Officer Bosak's murderer, as his last act in office. As of November 2022, he is still incarcerated, serving life without parole. Patrolman Bosak was a United States Marine Corps reserve Vietnam veteran and had served with the Chicago Police Department for over 12 years.

In tribute

I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.

Patrolman Bosak gave the Chicago Police Department 12 years.

Thank you for your service to the Chicago community, and for your service before it. Gone but never to be forgotten.

Rest easy, brother.

— S. Vincent Anthony, U.S. Army 1985-1993
