STONEHAM, Mass. (WPRI) — A Massachusetts State Police trooper died following a serious crash on I-93 late Thursday night.

Col. Christopher Mason said crews responded to the crash around 11:45 p.m. and arrived to find a large tanker truck carrying 10,000 gallons of gasoline partially pinning the trooper’s cruiser against the cliff wall on the side of the highway in Stoneham.

Trooper Tamar Bucci, 34, was pulling over to assist a disabled motorist when the crash occurred, and the force of the impact pushed the cruiser, which had its blue lights activated, off the roadway.

“Her death is the reminder of the danger troopers and police officers face each day in order to protect society,” Mason said.

Two good Samaritans stopped and pulled Bucci out of the heavily damaged cruiser. A Stoneham officer who came upon the scene performed emergency first aid and CPR until EMS arrived.

Bucci was rushed to Massachusetts General Hospital where she was pronounced dead.

“Trooper Bucci gave her life in the act of trying to help another person in distress. There is no greater act of sacrifice than to give one’s life for another,” Mason added.

The driver of the car Bucci was attempting to help was also brought to the hospital with minor injuries.

The truck driver, identified only as a Methuen man, was not hurt. Police said he was cooperative and interviewed by troopers early Friday morning.

State police said Bucci had only been a trooper for two years, but it was her dream job. Before joining the department, she worked as a security officer at Encore Casino and a personal trainer.

Bucci graduated from Andover High School and Middlesex Community College.

She is survived by her mother, father, two sisters, stepbrother and stepsister.

“Her selfless act embodied the mission of state police: to help those in need,” Mason said. “A mission we will now carry on in her memory.”

No charges have been filed at this time and the incident remains under investigation.

According to Mason, Bucci is the 22nd member of the state police to die in the line of duty.

Massachusetts Gov. Charlie Baker ordered the flags at all state buildings to be lowered to half-staff in Bucci’s honor.

“Trooper Tamar Bucci embodied the best of the Massachusetts State Police, and her loss is devastating to her loved ones, the Commonwealth and her brothers and sisters in blue,” Baker wrote on Twitter. “Our sincere and heartfelt thoughts are with Trooper Bucci’s family during this heartbreaking time.”
