State police say a trooper has died after falling into the gorge at Letchworth State Park in western New York during a training exercise.

Police say Trooper Ross Riley was transported to a hospital after the 1 p.m. Wednesday accident, but he succumbed to his injuries. Further information about the accident was not immediately released.

Riley, a 17-year veteran, was an experienced rappeller and a member of a state police unit called the Special Operations Response Team. He was on a six-person team that helped save an injured hunter near the bottom of a 500-foot-high rock face in Zoar Valley Gorge in 2010.

Riley was stationed at Batavia. His wife, Heidi Riley, is a trooper stationed in Olean. They have three children.
