A fire at a northeast Ohio nursing home Sunday that killed one and injured six others was caused by a meth lab that had been set up in one of the resident's rooms, authorities said.

The deadly blast occurred in a second floor room of the Park Haven Nursing Home in Ashtabula at around 8:30 p.m., firefighters said, sending staffers scrambling to save the home's three dozen elderly or disabled residents.

"I was taking a break, and I looked through the window and I saw an explosion of fire," nurse Deanna Bigley told the local Star Beacon newspaper.

"There was this guy and he was engulfed in flames,” she said. “One of our residents put him out, but then the fire started up and he had to be put out again."
