NEWPORT, Tenn. (AP) — Authorities are investigating a teenager's drowning at a rock quarry in eastern Tennessee.

Cocke County Sheriff Armando Fontes identified the victim as 14-year-old Tyler Sisk.

Media outlets report Sisk and a friend were walking in knee-deep water with poor visibility Saturday when they fell into a deeper section and went beneath the surface.

Fontes says the friend reached the shallow portion of the water, couldn't find Sisk and ran to a nearby home where authorities were called. Paramedics found Sisk's body near a steep drop-off after a 45-minute search.

The investigation is continuing.
