Retired Chicago Police Association

My dad was a member of the Chgo Police Department. He joined abt 1942 and retired abt 1972. I don't have much info on him. He was born Apr 22, 1916 in Co, Limerick, Ireland, came to this country abt 1926. He spent most of his time in the old 4th district in So Chgo.
Any help you can provide, I would appreciate very much.

Sincerely,
Patrick J. Maloney III
