A workplace shooting suspect whose body was found floating in New York's Hudson River had shot himself.

Nassau County police Inspector Kenneth Lack tells Newsday (http://bit.ly/19fL9bm) that Sang Ho Kim shot himself in the mouth. He says the 63-year-old had heart disease and drowned.

One person was killed and one was wounded in last week's shooting at a light fixture company in Garden City, on Long Island. Police say Kim had a business dispute with officials there.

Kim fled after the shooting. His car was found later in upstate Putnam County.

Kim's sister says he contacted her after the shooting to say he planned to commit suicide.
