The Washington County Sheriff’s Office has identified two of the three people who died when their single-engine plane crashed into a water-filled quarry last weekend.

The bodies of 60-year-old Larry Schlichting, of Eagan, and 24-year-old Lucas Knight, of North Mankato, have been recovered from the quarry on Grey Cloud Island near Cottage Grove.

Sheriff’s officials say a dive team continues to search for the third person who died when the Cessna went down last Sunday. Some wreckage of the plane has been recovered.

Authorities have said the recovery work has been difficult because of the large debris field in the quarry and the water’s depth of 70 feet.
