Early the next morning, authorities said they found her body near 100 Acre Island, a nature preserve in the middle of the pond. An autopsy later that day determined the 48-year-old woman’s death was a homicide.

Sunshine Stewart, 48, was found dead during a search last Thursday on Crawford Pond in the town of Union, Maine State Police said.

Police in Maine are investigating the death of a paddleboarder near a campground in rural Maine as a homicide and asking the public for help finding the killer.
