A second body has been pulled from the rubble of a Minneapolis school following a gas explosion and building collapse, the city’s fire chief said on Wednesday.

Minneapolis Fire Chief John Fruetel declined to identify the second victim, pending notification of next of kin. Nine people were hurt in the blast at about 10:20 a.m. central time.

Crews were called to Minnehaha Academy in Minneapolis, Minn., after part of the building collapsed Wednesday morning. Nine people were rushed to hospital after the explosion, three of which were in critical condition.

According to the Minneapolis Tribune, the first victim was Ruth Berg, a longtime receptionist at the school. The Minnehaha Academy later confirmed this.

“Ruth worked for Minnehaha Academy for 17 years. As our receptionist, she welcomed everyone with a smile and was always willing to go the extra mile to help our students, families, and staff. She will be greatly missed,” officials wrote on the Facebook page.

Earlier on Wednesday, one other was still unaccounted for, and Fruetel still considered it a “rescue mission.”

“It’s just a very precarious situation, it’s very very unstable, there are no signs of (their) obvious location and we know there are probably at least two floors of debris,” Fruetel said at the time. “We still consider it a rescue at this point.”

Later in the evening, the second body was pulled from the rubble, which has yet to be identified.

The gas leak occurred as contractors were working on the building, police said.

Paul Meskan, who lives across the street from the school, said he was pulling weeds when the blast happened, and he ran over to the school. Meskan said he and other people who rushed to help found a man pinned under the rubble.

“We just started digging,” Meskan said, noting that after police and firefighters arrived, “we kept digging, and gas, gas was going. Fire was going.

“And it’s like, ‘we’re not going back until we get this guy out of here.’ And we got him out, and they got him on a stretcher.”

The Star Tribune reported that city records show Master Mechanical Inc. was issued a permit on June 7 for “gas piping and hooking up meter” at the school’s address. Ryan Larsen, a company official, released a statement saying the company was monitoring the situation and referred all questions to the Minneapolis Fire Department.

“It would have to be a significant explosion to take out that brick,” police said. “It would be a lot more significant if it was school time. It is a good thing it was summer as it probably the limited the number of people who could have been hurt,” he said.

The school is a Christian private school for students in preschool through Grade 12.

It’s not known how many people were inside the school at the time.
