I worked for John back in the 1980's, as a Detective, in the DA/Rackets Bureau. He was always smiling and made my day, with his wit and humor. A gentleman and a great cop. Always there for his men. A great leader who was very well liked and respected. I will miss him and keep him in my prayers and memories always.

I was Chief ADA in Rackets when John was the Commanding Officer of the Rackets Squad in the 80's with 50+ Detectives. A very busy place and a tough job. John was great and a pleasure to work with. A Cop's Cop, a prosecutor's Cop and he always was a real gentleman. RIP my friend, Don Sullivan
