SILVER SPRING, Md. (AP) — Investigators have found a cut gas pipe in the basement of a Maryland four-story apartment building destroyed by an explosion and fire, but investigators are working multiple theories on the cause, a fire official said Friday.
It is possible a maintence worker who was working on plumbing at the Friendly Garden Apartments in Silver Spring at the time of Thursday’s explosion cut the gas pipe, Montgomery County Fire Chief Scott Goldstein said at a briefing. It’s too early to say whether it was cut accidentally, he said. Investigators don’t have an ignition source, he said. The worker, who was injured in the blast, has been able to talk to investigators, he said.
