To my grandpa...the best teacher and provider I ever met grandpa you always believed in me when I was in little league all the way up till I became a man
You were always there for me with advice and told it how it was...I will always remember watching baseball games and jeopardy with you as you always got all the answers correct...I love you grandpa
Love your grandson

My deepest condolences to the Ocallaghans. He was a great father and a great man. We grew up running in and out of his home as kids. I always stopped and talked to him when I was visiting my parents house on School St. May God grant your family peace and may his memory be forever eternal.

MY deepest condolences to the ocallaghan
family. I WAS A FRIEND OF TOM AND ALL OF
OCALLAGHANS MANY YEARS AGO.

My sincerest and deepest condolences go out to Tom's family. I go way back with Tom to 1967 when he broke me in on the job. He was a great police officer and a great teacher. His skills and training stayed with me for 34 years on the job. I know he will be deeply missed. My thoughts and prayers go out to his entire family.

Sincerely,

Brian E. DuFour, USN (Ret.)
Chicago Police Department - Retired

Always a gentleman. Tommy was a great policeman and had the patience of a Saint, RIP brother.

My condolences to Tom's entire family
Worked with Tom in the old 015 and remember him as one of the older guys who alway helped and defended the rookies coming into the district
Although he never was a field training officer he mentored many rookies who went on to become bosses in the CPD

May you be three days in heaven before the Devil knows you're gone
