The body of a swimmer has been found after he went underwater in Lake Lanier on Saturday and did not resurface.

Divers pulled the body of 23-year-old Anthony Saintil from the lake about 1 p.m. Sunday, according to Georgia Department of Natural Resources spokesman Mark McKinnon.

Authorities said Saintil jumped into the lake off a pontoon boat about noon. He was last seen in the area of Flat Creek, according to McKinnon.

Authorities searched for him into the night Saturday and resumed the search at 8 a.m. Sunday. Searches used sonar scanners and found Saintill near the mouth of Balus Creek.
