Authorities say a man who drowned in a lake at Virginia Beach's Mount Trashmore Tuesday went under while trying to retrieve a toy boat that had gotten stuck in the water.

Police identified the victim as 31-year-old Frank Perez of Virginia Beach. His body was retrieved from the lake around 1:15 a.m. Wednesday.

Witnesses tell police he went into the lake around 8 p.m. Tuesday trying to retrieve a motorized toy boat. Police say at least one person tried to rescue him and another called 911 when he didn't resurface.

Boat and dive teams searched for the man but were unsuccessful.

Mount Trashmore is a landfill that has been converted to a park.
