A Massachusetts police department is mourning the death of one of its own after an officer was struck and killed while attempting to assist a broken-down driver on a highway.

The Uxbridge Police Department has hung black bunting above its main entrance as it receives condolences from across the Bay State following the incident early Wednesday morning.

The crash unfolded at about 12:45 a.m., when the officer was trying to help a motorist in the northbound lanes of Route 146, a main artery in the Worcester County town that borders Rhode Island.

Authorities identified the fallen officer on Wednesday afternoon as Stephen Laporta, 43, of Uxbridge. The Massachusetts State Police is investigating the crash.

“This is a devastating loss for our department and our community,” Police Chief Marc Montminy said in a statement. “Our thoughts and prayers are with the officer’s family, loved ones, and fellow officers during this incredibly difficult time.”

Gov. Maura Healey has ordered flags to be flown at half-staff at all state buildings in honor of LaPorta.

“I am heartbroken over the news of Officer Stephen LaPorta’s passing,” the governor said in a statement Wednesday afternoon. “He knew he was headed into a dangerous situation when he responded to the scene of a multi-vehicle crash, but like all of our officers do day in and day out, he put the public’s safety first – and he tragically made the ultimate sacrifice.”

Authorities closed Route 146 for hours after the crash, with investigators working the scene. The icy, frozen road reopened around 10 a.m.

Uxbridge First Holy Night, a community organization, offered its condolences to the department via social media, saying the loss is also felt “across our entire town.”

“Our officers are more than public servants — they are neighbors, friends, parents, children, and family,” the group stated. “When one of our own falls, we all grieve together.”

“Uxbridge is a close-knit community,” it added, “and in moments like this, we lean on one another. May we surround this family and our police department with compassion, strength, and support in the days ahead.”

Police departments from across the region sent cruisers to participate in a procession that accompanied a vehicle carrying LaPorta’s body to a medical examiner’s office before daybreak.

The Boston Police Patrolmen’s Association described the officer as a “fallen hero” and the death as “heartbreaking news.”

“Another police officer killed in the line of duty. This time in Uxbridge,” the association stated in a social media post. “The officer was involved in a motor vehicle crash while attempting to assist a motorist on Rte. 146 early this morning. Our thoughts and prayers are with the officer’s family and the entire Uxbridge Police Department during this incredibly difficult time.”

State Rep. Mike Soter, whose Central Massachusetts district includes Uxbridge, said his “heart sank” when learning of the death.

“This is so close to home,” he said in a Facebook post. “May GOD watch over this officer’s family and his fellow officers today as they need our strength as a community. May the officer’s memory be eternal always!”

In June 2024, the Uxbridge Police Department celebrated LaPorta’s promotion to full-time patrolman.

“He may seem familiar to you all because Ofc. LaPorta has already been actively serving our wonderful town as a full-time Dispatcher and working part-time patrol shifts,” the department stated in a Facebook post. “He has put in the work to switch his role up and come to the patrol side full time! Let’s give him a warm congrats Uxy!”
