Two “suspicious” fires at a former school are being investigated as arson, as officials ask the public for help in the investigation.
The fires at the former Fernald School campus in Waltham this month might be related to recent fires in January and last December, according to fire officials.
“We are asking anyone with information on recent fires on the Fernald grounds to share it with investigators,” said Waltham Police Chief Kevin O’Connell.
“There have been four fires in that area since December,” the chief added. “These incidents are dangerous, and we’re deeply concerned that someone is going to be hurt.”
In the early morning hours of April 19, the Waltham Fire Department responded to 200 Trapelo Road for a report of a fire. Firefighters found heavy fire in two structures – one known as the Schoolhouse/Gym and the other the Manual Training Building.
The incident went to four alarms, drawing mutual aid companies from several nearby departments. Firefighters battled the flames for more than 6 hours before they were finally extinguished.
Investigators from the Waltham Fire Department, Waltham Police Department, and State Police Fire & Explosion Investigation Unit assigned to the State Fire Marshal’s office believe the fires were set intentionally and separately.
“These buildings were vacant, but any structure fire is inherently dangerous,” said Waltham Fire Chief Andrew Mullin. “Firefighters confronted heavy smoke and flames venting out the windows.
“They were present when the roof of one building collapsed and the first floor of another collapsed into the basement,” the chief added. “First responders, curious onlookers, and even the person or persons responsible could have been injured or worse.”
Investigators believe the April 19 fires could be related to two others on the Fernald grounds in recent months. One was reported in the early evening of Dec. 14 at the Chapel of the Holy Innocents, causing minor damage.
The other was reported in the late morning of Jan. 18 at Chipman Hall, causing catastrophic damage that included a roof collapse. Like the April 19 fires, both of these fires took place on Saturdays.
“If you were in the area of the Fernald School on these dates and saw anything suspicious, or if you have specific information on the person or persons responsible, please share it with investigators at 1-800-682-9229,” said State Fire Marshal Jon Davine. “You can remain anonymous if you prefer. What’s most important right now is that these fires stop before someone gets hurt.”
