The 17-year-old suspect in the murder of a paddleboarder earlier this month will appear in court on Friday, where he is expected to be charged with one count of murder. Sunshine Stewart was found dead on July 3 at Crawford Pond in Union, Maine. Her cause of death was strangulation and blunt force trauma, Maine State Police revealed Thursday.

Police in Maine said Thursday they have arrested a 17-year-old state resident in connection with the killing of a paddleboarder who went missing on a rural pond.

The medical examiner later revealed her cause of death to be strangulation and head trauma, citing the “unusual circumstances” around her demise.
