The New Hampshire Fish and Game Department said the body of Casey Smith Jr., of Lunenburg, Vermont, was found shortly before 2 p.m. in the river near where he was last seen. He disappeared while swimming below the Bridge Street bridge around 5:30 p.m. Monday.

Fish and Game Sgt. Mark Ober said although accidents like this don't usually happen in the Connecticut river, his department is used to these kinds of searches.

"We do this in different bodies of water throughout the state -- rivers, lakes and ponds," Ober said. "So we're pretty familiar with this sort of procedure."

Officials said the teen was swimming with his two sisters and three other friends Monday evening in the river in Dalton, New Hampshire, when he began to struggle in swift water.

One of the other swimmers was caught by the same current and had to be pulled to safety by a Good Samaritan who heard cries for help.

Dalton Fire Department and the Coos County Sheriff's Department, along with the Lunenberg Fire Department and Vermont State Police assisted with the search.

Search parties combed the river banks and scoured the water. Surrounding communities also volunteered to help with the search.

Crews called off the search about 10:30 p.m. Monday, but resumed their efforts Tuesday morning.

An autopsy will likely be performed to determine the teen's cause of death.
