Federal prosecutors want to keep cash found in the luggage of a man who died of a heart attack in a New York train station.

FOX News Radio's Courtney Kealy reports:

William Coyman died of a heart attack in August 2011 after getting off an Amtrak train in New York at Pennsylvania Station. Federal prosecutors say the retired teamster had a criminal history going back as far as 1955.

They want to hold on to the almost $180,000 in cash in plastic bags found by medics in Coyman's backpack, saying it's suspected that the money was the profits from drug trafficking.

He served prison time in New Hampshire for cocaine possession and stealing $20,000 from a department store. Coyman's union, International Brotherhood of Teamsters Local 25, was known for its organized crime times in the 1990's.
