HELENA, Mont. (AP) — The city of Helena has reached a $100,000 settlement with a teacher who suffered hearing damage during an active shooter drill at an alternative high school.

Lynn Trenary sued saying she suffered hearing loss and a permanent ringing in her ears after an officer fired a blank near her during a June 2016 exercise to train teachers how to respond to a school shooting.

The city initially responded that Trenary had been told to cover her ears and that it was possible her hearing damage came from a prior incident.

The Independent Record reports the lawsuit was formally dismissed last week. The settlement reached in May protects the city from any further legal action in the matter.

The city confirmed Friday it is now using air rifles in active shooter training.
