A cause of death has been revealed for a paddleboarder who was killed in a Maine pond as police confirmed a teenager, 17, has been arrested in connection with the murder.

Sunshine Stewart's body was found during a search of Crawford Pond, a 600-acre body of water in Union, southern Maine, after she disappeared on July 2.

The name of the 17-year-old is not being released at this time. Police say he has been charged with one count of murder.

A Maine teenager has been charged with killing a woman who disappeared while paddleboarding on a rural pond earlier this month, authorities said Friday. The disclosure of the charge and his name came after a Maine judge ruled that under state law the case against the juvenile should be opened to the public, according to Frey’s office.
