I knew there was a reason I hadn't seen him in awhile. He was extremely talented. Homicide Life on The Street,Men of a Certain Age, Frequency his performances in the aforementioned were absolute perfection. Rest well brother.
Never saw Brooklyn Nine Nine, but I liked him a lot as an actor in movies he appeared in and especially on television with "homicide life on the street". That was one if my favorite shows back in the 90's.
This really drives home that the life you have or live is not forever .
