The body of a New Hampshire man who left home in 1998 for a horseshoe tournament has been found.

Tony Imondi left his home on July 1, 1998. He drove off in his girlfriend's pickup truck, on his way to the tournament. He was never seen again, WGME reported.

That was until Tuesday, when police using sonar equipment found the truck at the bottom of the Androscoggin River in Errol, New Hampshire.

Police found Imondi's skeletal remains inside the truck when they pulled it from the water, WGME reported.

Now police are investigating why the truck plunged into the river.
