More details have surfaced about a tragic drowning in Clearfield County that claimed the life of a 19 year old.  Coroner Micheal Morris said over the phone today's autopsy on Dylan Keith points to an accidental drowning.  The Houtzdale teen slipped below the surface at Wopsononock  Pond in Gulich Township around 3 Saturday.  A good samaritan jumped in to help and was drug down.  She resurfaced but was unable to bring him back up.  Dive Crews reported visibility of only 3 feet in the murky water and had to use ropes in the 14 foot deep section of the pond.  The Coroner is waiting for test results to rule out an underlying medical condition.
