Authorities on Wednesday identified the teenager who died after being pulled from Cedar Lake in Minneapolis over the weekend. She had been underwater for an extended period.

Chiccena Carpenter, 16, of Minneapolis, was found about 2 p.m. Sunday in about 10 feet of water, after apparently trying to swim to shore from a floating platform. Carpenter died Monday at Hennepin County Medical Center.

The Hennepin County medical examiner's office ruled her death an accidental drowning.

Not all Minneapolis beaches have lifeguards on duty. Last year, five of the 12 beaches had guards.

The Minneapolis Park Board decided this year to add two more, including one at the beach where the girl drowned.

But because of a lifeguard shortage, the beach isn't expected to have guards on duty until this Saturday, said Dawn Sommers, a Park Board spokeswoman.
