WATERLOO TOWNSHIP (WKOW) -- Authorities say a 17-year-old drown on Saturday after diving headfirst into Grant River.

Multiple emergency agencies responded to the scene, which was an area on the Grant River along Pigeon River Road in the Waterloo Township, to attempt to locate Lynn Zimmerman, 17, of Livingston.

Zimmerman was declared deceased at the scene.
The Grant County Sheriff's Office said Zimmerman was with a group of 12 friends and family, who were canoeing the Grant River when they stopped to go swimming.

The Grant County Sheriff's Office is conducting the investigation into the incident.
