LYNN, Mass. - An elevator exploded in an office building Wednesday, and authorities began investigating it as a murder-suicide after they found the bodies of a man and woman inside.
Essex District Attorney Jonathan Blodgett said the deaths in downtown Lynn, near Boston, appeared to be a "domestic violence situation by use of an incendiary device."
Two people were taken to hospitals with minor injuries, police said.
Witnesses said a man pulled a woman into the elevator, The Daily Item of Lynn reported. Shortly afterward, an explosion engulfed the elevator, police said.
Firefighters extinguished the blaze and found the bodies.
Employees said the woman worked as a receptionist for a psychiatric clinic in the building.
"I heard a lot of screaming," said attorney Phil Lamonica, whose law office is in the building. "At first, we all thought she was trapped in the elevator and had claustrophobia, so we started punching all the buttons. I ran to call the fire department and while I was on the phone, I heard the explosion."
The blast shook the three-story building, said Sam Gonzales, who was in a dentist's chair on the first floor.
"The ceiling started coming down, so we got out," he said.
