ROANOKE, Va. — An autopsy has concluded that an Indiana man whose body was found off the Appalachian Trail in Virginia was suffocated.

The body of Scott Lilly of South Bend was found Aug. 12 in Amherst County by hikers. The News & Advance of Lynchburg says the Roanoke medical examiner released the cause of death on Friday.

Lilly’s remains were discovered just off the trail in the Mount Pleasant National Scenic Area east of the Blue Ridge Parkway.

The FBI calls the death suspicious. The agency is investigating because the body was found on federal lands.

Hikers who had seen Lilly said he was traveling alone and toting a lot of gear.
