Hartland Fire Company volunteer fire police officer Judy Spencer was killed late Tuesday in Somerset as she guided the driver of a fire truck when the vehicle backed into and ran over her, the Niagara County Sheriff's Office reported.

Deputies say the fatal accident was reported at about 8:40 p.m. on Quaker Road, where units from several fire companies had responded to a fire in a field.

Investigators from the Sheriff's Office and Somerset town police determined a Barker Fire Department rescue truck was moving in reverse, southbound on Quaker when the rig struck and ran over a fire police member from Hartland who was acting as a spotter for its driver.

The Hartland volunteer died at the scene. The operator of the rescue truck wasn't injured.
