The Kennebec Journal reported (http://on.wcsh6.com/1K36yG3 ) that 17-year-old Scott Brown of Norridgewock was swimming to shore from floating docks when he went underwater at about 7 p.m. Sunday.

Officials say he wasn’t entangled in anything that would have held him under and they’re not sure why he drowned. They say dehydration or a muscle cramp could have contributed to the drowning.

The newspaper reports that Brown had been swimming with his 13-year-old brother and two teenage girls when he drowned.

He was an honor roll student and a member of the Skowhegan High School football team, according to WGME.
