A Sloatsburg man drowned Sunday while swimming at Seven Lakes. New York State Police Major Paul DeQuarto of Troop F says 43 year-old Bogdan Kardynal was last seen entering the water Sunday night around 8:15 from the Sebago Boat Launch, but he went under and did not resurface. The Thiells Fire Department and Water Rescue found Kardynal’s body a short time later and removed him from the lake. The Rockland County Medical Examiner declared him dead at the scene.
