A man apparently drowned Sunday during a swim race in Reston, the Fairfax County police said Monday.

They said Kevin Ruby, 45, of Falls Church was competing in Lake Audubon, but a family member had not heard from him and became concerned.

Police said officers went to the scene and determined that he had never reported in at the end of the race.

Police began a search Sunday. It resumed Monday, and Ruby’s body was recovered. They said a medical examiner will determine the cause of death.

Foul play is not suspected, police said.
