LAKESIDE, Mont. (AP) — Authorities say dozens of people are injured, some critically, after a second-story deck collapsed at a Montana lodge where a memorial service was being held.

The Daily Inter Lake newspaper reported a woman said she was among about 50 people on the deck at Glacier Presbyterian Camp Saturday afternoon when the structure overlooking Flathead Lake collapsed.

Leslie Dillon told the newspaper she walked away with some bruising, but many of her friends and relatives were taken away by ambulance.

First responders rushed adults and children to various medical facilities while the critically injured were airlifted to hospitals.

The newspaper reported that law enforcement officials said the incident was under investigation.

The crowd was gathered to remember William Nickel, a longtime Flathead Valley firefighter who died in April.
