PORTLAND, Maine — Authorities in Maine said Friday they have charged a 17-year-old with murder in the death of a paddleboarder who went missing on a rural pond that is a popular summer destination.

The body of Sunshine Stewart, 48, of St. George, was found this month on Crawford Pond in Union, about 80 miles north of Portland and about 15 miles from some of the state’s scenic coastal areas. The killing shocked and scared the community, where trips to the pond and nearby campground are a summer staple.

Maine State Police said a 17-year-old boy was taken into custody in Union on Wednesday night in connection with the homicide investigation but initially did not elaborate and declined to release additional information about him. On Friday, the state attorney general’s office said the teen was charged with one count of murder.

Court documents identified the teen as Deven Young, of Frankfort, Maine. He made a brief initial court appearance on Friday in which he entered a denial to the charge. His attorney, Jeremy Pratt, declined to comment to The Associated Press via email.

A medical examiner determined Stewart’s cause of death was strangulation and blunt force trauma, police said.

Authorities have not revealed a motive. Court documents contain little detail other than stating that Young is a juvenile and “did intentionally or knowingly cause the death of another human being, namely Sunshine Stewart.”

Police said in a statement Friday that they were not releasing any additional information and that the case was “still a very active investigation.” They have said they are seeking information from anyone who may have seen Stewart paddleboarding on July 2 on Crawford Pond.
