A Fairfax County police diving team yesterday recovered the body of a Virginia high school student who fell 75 feet from a rock ledge into a water-filled quarry in Lorton, police said.

Mark A. Cicioni, 18, of 1995 Cumberland Dr. in Woodbridge in Prince William County, was lowering himself into the quarry on a rope tied to a tree about 8 p.m. Saturday when the rope broke, police said. Two Woodbridge brothers who were with Cicioni told police he hoped to spray-paint his name on the rock wall.

The brothers tried unsuccessfully to find Cicioni after he fell, police said. Police and fire rescue units, as well as a county helicopter pilot, searched the area until 11 p.m.

The search resumed yesterday morning at 8, police said, and divers found the body at 10:30 a.m. Cicioni, a senior at Woodbridge High School, was submerged in 10 feet of water, about 15 feet from shore. Police said an autopsy will be performed.

The quarry, located in southern Fairfax County off Rte. 123 near the Prince William County line, is owned by the Vulcan Materials Co. but is on property owned by the Fairfax County Water Authority. Police said it is not open to the public.
