The hunt for the man wanted in the Long Island workplace shooting that killed one and critically injured another ended Monday when the suspect was found dead along the Hudson River in upstate New York, authorities said.

Police found the body of Sang Ho Kim, 64 years old, around 9:30 a.m. in the water near Iona Island, about 11 miles south of Cold Spring, N.Y., where police located his 2007 white Honda Pilot a day after the Sept. 25 shooting, authorities said.

Nassau County investigators positively identified the body as that of Mr. Kim through a fingerprint match, spokesman Det. Michael Bitsko said.

New York State Police in Monroe assisted State Park Police in recovering the body.

"The body appears to have been in the water for several days," Major Patrick Regan, the commander of the local state police barracks, said in a news release.
