What Happened

Patrolman James J. O'Brien was shot to death and his partner was critically wounded at 1:45 A.M. at the southwest corner of 63rd and Halsted Streets by an 25-year-old auto thief who was also wounded by O'Brien's partner. The officers came upon him as he was tampering with a car door lock. Although wounded, he escaped in a stolen car but was captured the same day in a doctor's office in Oak Lawn where he went for medical aid. On September 17th, 1928, he was held by the coroner to the grand jury, which indicted him for murder. The suspect, age 27, was convicted of Patrolman O'Brien's murder and sentenced to 30 years in prison on January 25th, 1929. He applied for clemency on April 8, 1939. He was released at some point between 1941 and 1943. The exact date is unknown. Patrolman O'Brien had served with the Chicago Police Department for six years and was assigned to the 15th District. He was survived by his wife and five sons. He was a World War I veteran.

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 O'Brien gave the Chicago Police Department 6 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
