Two die in blast at Minneapolis Christian school

An explosion Wednesday at a Christian school in Minneapolis killed two people, injured several others, and ripped apart a building, fire officials said. Investigators believe a natural gas leak caused the blast at Minnehaha Academy, which has pre-kindergarten through 12th grade classes. The explosion killed Ruth Berg, a receptionist for 17 years at the school who “welcomed everyone with a smile,” the school said in a statement. John Carlson, a part-time janitor known for giving Dilly Bars to students, was reported missing. The 81-year-old attended the school as a child, sent his own children there, and was like a grandfather figure to students, school officials said. Officials have not confirmed whether Carlson’s body was the second one found. Four people remained hospitalized late Wednesday, including one in critical condition.
