"This was his normal routine. Check in, go to his car, wait to get his post," said Lt. Gerald Palkofsky from the Suffolk County Police Department.
"One shot was fired, hit him in the neck, left side, causing this severe injury," Lt. Palkofsky added.
Coworkers desperately tried to help him and called 911. Hirt was rushed to the hospital but three hours later he died. What mystifies police and friends is motive.
