A coroner says one man was fatally injured when a lift collapsed at a southern Indiana high school football field.

Jasper police say emergency crews were called about noon Monday to Jasper High School’s football stadium.

Dubois County Coroner Bob Veatch tells The Dubois County Herald that the lift was being used to install lights at the football field tipped over. The lift was extended about 40 feet at the time of the accident .

Authorities tell WFIE-TV that workers from Hulsman Electric were 62-year-old Earl Hulsman and 60-year-old Kurt Brescher. They believe the men were bringing the lift down to the ground and for an unknown reason, the lift tipped and fell to the ground.

Veatch says said Hulsman was killed. Brescher’s injuries are not believed to be life threatening.
