Ten people, including the shooter, were killed and at least 25 were injured in a shooting at a school in Canada’s British Columbia on Wednesday, police said.

The Royal Canadian Mounted Police (RCMP) said the suspect, identified as a woman in a dress with brown hair in an earlier alert, has been found dead within the school premises with what is believed to be a self-inflicted injury.

Six people were found dead at the school, one died on the way to the hospital and two were found dead in a residence in the community, police said. Two people were airlifted to hospital with serious or life-threatening injuries.

The Tumbler Ridge police issued a 2 pm alert after the incident around 1.20 pm local time at the Tumbler Ridge Secondary School, describing the suspect as a  female in a dress with brown hair, per Globe and Mail. Residents were asked to shelter in place, lock their doors and refrain from going outside. The shelter-in-place order was lifted around five hours later, allowing people to return to their daily activities.

Cops continue to ascertain if a second suspect was involved and the number of possible victims.
