Officials have pulled back on the search for an Atlanta woman who went under at Lake Lanier.

“We scaled back the search beginning Saturday morning, as we believe we have covered the area as thoroughly as we can with the equipment,” Mark McKinnon of the state Department of Natural Resources said.

The woman, 31-year-old Madeline Sinagra, got tired while swimming July 22 and could not make it back to her boat, authorities said.

A man on the boat tried to rescue Sinagra when she became tired, authorities said. After attempts to throw a line to her failed, the man went in after her, he told deputies.

“The male reported that he then went into the water in an attempt to rescue the victim, but was unable to locate her after she went under and did not resurface,” sheriff’s spokesman Sgt. Stephen Wilbanks said in a statement.

Sinagra wasn’t wearing a life jacket, officials said.

“During the week, we dropped the sector scan sonar to the bottom almost 300 times,” McKinnon said, “while also utilizing DNR helicopters, side scan sonar, Hall County divers and a cadaver dog.

“We will continue to perform surface searches as part of our patrols several times a day and we hope to bring closure to the family soon.”
