A 2-year-old boy is in life-threatening condition at Inova Fairfax Hospital after being found, unresponsive, at the bottom of a pool, Fairfax County Police said.

The boy was discovered when the pool at Pirate’s Cove Waterpark at Pohick Bay in Lorton was being cleared Sunday, June 14 for lightning.

Marine Patrol Unit officers from Fairfax County Police arrived at the pool first and initiated chest compressions on the boy. They were relieved by personnel from Fairfax County Fire and Rescue, who continued with cardiopulmonary resuscitation.
