Jack Lee Cooper

Sergeant Jack Cooper was shot and killed in the 2600 block of Kennedy Avenue while checking the identification of two men who matched the description of suspects in the earlier shooting of a police officer.

While his back was turned, Sergeant Cooper was shot three times in the upper chest region. One of the suspects' driver's licenses was found in Sergeant Cooper's patrol car.

The suspect and his brother were apprehended in New York City during a massive manhunt. They were both charged with Sergeant Cooper's murder and sentenced to death, but both sentences were commuted to life. One brother committed suicide in prison, and the other tried to escape prison on two occasions and was captured and returned to prison on both times.

Sergeant Cooper had served with the Baltimore City Police Department for 16 years. He was survived by his wife and two daughters.

Growing up, my Grandfather, Sgt Ernest W. O'Connor - retired, spoke about Sgt Cooper with many fond memories and always spoke about what a great guy he was. They worked together for years and were good friends. My mother remembers as a little girl Sgt Cooper visiting her house with my Grandfather and always had kind words to say about him. My Grandfather said that Sgt Cooper's death was his saddest day as a policeman.
I'm sure his family knows this, but Sgt Cooper was well loved as a friend, father, husband and a brave policeman.
Rest in Peace.
