9 Massachusetts State Police Frankies shot and killed during standoff, first MSP canine killed in line of duty

A state police K9 at large was shot and killed during a standoff in Fitchburg Tuesday afternoon, a “heartbreaking” loss as Frankie became the first MSP canine to be killed in the line of duty. .

Frankie, a 10-year-old Belgian Malinois who had been a member of the Mass. State Police for nine years, was shot and killed while trying to apprehend a wanted fugitive who had barricaded himself inside a residence. Frankie’s handler, Trooper David Stosinski, was not physically injured.

“His sacrifice will never be forgotten,” Colonel Christopher Mason said at a press conference announcing Frankie’s death. “Frankie possessed every trait we look for in a good law enforcement officer, canine or human: intelligence, immense courage, and a dedication to public safety. He was as loyal a companion as any trooper.

“He was a beloved member of the Massachusetts State Police family and the Stosinski family,” Mason added. “He, like any human member of the department, was one of us and a part of us.”

The fugitive suspect — Matthew Mack, 38 — later died after apparently shooting himself inside the three-story multifamily home at 40 Oliver St.

Mack was wanted on warrants charging him with felony firearms and possession of a firearm after a shooting incident in Fitchburg last week.

When troopers made verbal contact with Mack, he refused to come out of the house. Negotiators held several talks with Mack, as well as his family members, to persuade him to surrender peacefully.
