The man rescued from Gunners Lake in Germantown on Independence Day has died, Montgomery County police said Thursday.
Police identified the man as 38-year-old Brian Walton, of Gaithersburg.
Walton and a friend were operating a radio-controlled sailboat on the lake when the 2-foot-long boat became disabled about 30 yards from the shore. Walton then waded into the water to retrieve the boat. He had difficulty getting back to shore, yelled to his friend for help, then disappeared into the water, police said.
His friend got into the water and brought the man back to shore. The friend and a bystander began CPR until rescue crews took the man to a hospital.
Police said authorities are still investigating why the man got into trouble in the water. The lake is 8 to 10 feet deep at its deepest point.
The lake is located at Wisteria Drive and Sky Blue Drive.
