Extra police will patrol a Virginia, quarry this weekend following the death of a 18-year-old Triangle man.
Fredericksburg police said Anthonly Mandel Johnson, Jr., 18, was swimming toward a rope swing at the quarry near the Rappahnnock River at the end of Wicklow Drive when he began struggling in the water. A friend tried to save him but was unable to do so.
Dive teams recovered the victim from the water about 45 minutes later. He was pronounced dead at a hospital.
Doctors believe cold water shocked Johnson's muscles and forced him into fatigue, according to his mother, Yolanda Johnson. She told Northern Virginia Bureau reporter David Culver her son was an excellent swimmer.
Police said the quarry is private property and there are posted signs against trespassing. However, it is a commonly known site for swimming.
Police will patrol the area around the clock to prevent people from sneaking in to swim.
