LAWRENCE — A father and his 13-year-old son were airlifted to a Boston hospital with serious burns yesterday afternoon after an explosion ripped through the basement of a Woodland Street home owned by a city police officer where the father had been doing maintenance work.
Investigators believe the blast was accidental.
A fire dispatcher said the boy was burned over 60 percent of his body, but had no information on the injuries to the father.
A neighborhood boy who biked to the house at 71 Woodland St. said both father and son were talking as they were carried in stretchers up the asphalt driveway and loaded into ambulances just after the explosion at 2:20 p.m. He said the father had an oxygen mask over his mouth.
Both were taken to Lawrence General Hospital, then by helicopter to Massachusetts General Hospital. A hospital spokeswoman could not comment on their conditions without their names, which Deputy Fire Chief Brian Murphy was withholding pending notification of family.
Murphy also would not provide their hometowns, but said they did not live in the house.
He said the cause of the explosion is under investigation, but said he believed it was an accident.
“It was accidental, with no violation of law, no illegal activities,” Murphy said. He said there was minimal fire damage to the basement and that the house suffered no structural damage.
The tidy green and white two-family paneled house, on a street of similar two-and-three family homes, also did not appear to be damaged. It was occupied by at least one person at the time of the explosion.
The house is owned by Gary Yancey, a Lawrence police officer who testified last month before a grand jury investigating alleged criminal wrongdoing by Mayor William Lantigua and members of his administration. Yancey is assigned to a special operations division of the Police Department, but until recently was assigned to City Hall and occasionally drove the mayor.
