WOOLWICH – A 37-year-old Brunswick man died Sunday night at Mid Coast Hospital after being pulled to shore from the Nequasset swimming hole.

A statement from the Sagadahoc County Sheriff’s Department described the death of James M. Knowlen as an apparent accidental drowning.

Sandra Knowlen, 66, had tried to get her son out of the water while he was in distress, the statement said. After her son went under, she sought help from a bystander, who found the submerged victim and dragged him 30 feet to shore.

Emergency responders performed CPR and continued to Mid Coast Hospital, where Knowlen was declared dead at 8:40 p.m.

The sheriff’s office is investigating but, according to the statement, has no reason to suspect foul play.
