According to various websites David Caruso DOES NOT WISH TO RECEIVE FANMAIL ANYMORE:
People do me a favour - LEAVE ME ALONE!!!
I don’t want to get any - love letters - fan mail - home-made jam, flowers, underwear. Please don’t bother me with your requests for autographs, stories of your life etc. I couldn’t care less. Get a life. I will never ever meet any of you left alone answer your silly letters again. I have given orders that every letter addressed to my mail-drop at Beverly Hills or to the set on Manhattan Beach will be send back or be destroyed.
I do not wish to get any fan mail anymore. Thanks, David
