Montgomery County police have identified a man who died while swimming in Triadelphia Reservoir in Brookeville last week as Avery Troix Williams, 19, of Germantown.
Williams was last seen on June 4, swimming with a group, officials said. Police said in a news release that Williams began struggling in the water, then went under the surface. His friends called 911 for help.
Montgomery County Fire and Rescue Service spokesman Pete Piringer said the body was found at about 2:30 p.m. on Friday in the area where rescue workers had been concentrating search efforts. The body was located about 65 feet from shore, in about 25 feet of water.
The Charles County Dive Team and divers from the state Department of Natural Resources were in the water at the time the body was located.
Piringer said Williams was swimming near the Greenbridge Recreation Area on June 4 with a group of about a dozen people, all in their late teens and early 20s.
Swimming is prohibited in Triadelphia Reservoir.
“They attempted to swim across the cove, and he went down and didn’t resurface,” Piringer said. “They were able to call 911 pretty quickly, and units from Howard and Montgomery counties responded.”
The search, which used sonar and thermal imaging, continued into the evening until a storm led the operation being suspended. The search continued all day on Thursday and resumed Friday morning.
