Lunged at cops with knife, shot dead

Police in Vermont and Massachusetts are continuing to investigate the circumstances surrounding the suspicious death of 23-year-old Mary Anderson of Harvard, Massachusetts.

Matthew Davis

State police say a concurrent investigation also remains active into the fatal police shooting of Matthew Davis, who is considered a person of interest in her disappearance and death. Davis, 34, of Fitchburg, Massachusetts, died following an officer-involved shooting Tuesday night in West Brattleboro. The shooting occurred after a short foot pursuit when Davis pulled a knife and lunged at police who were seeking to speak with him regarding Anderson’s death.

Autopsies on Anderson and Davis were planned for Wednesday, July 20, 2022, at the Vermont Chief Medical Examiner’s Office in Burlington, but that work now is not expected to be finalized before Thursday.

The two Vermont State Police troopers who fired their department-issued handguns are Detective Sgt. Jesse Robson and Detective Sgt. Samuel Truex. As indicated in a previous release, under department policy related to critical incidents, they will be on paid administrative leave for a minimum of five days.

Robson joined the state police in 2001 as a trooper assigned to the Shaftsbury Barracks. He was promoted to sergeant and patrol commander in 2012, and then transferred in 2018 as a detective sergeant to the Bureau of Criminal Investigations – Troop B East out of the Westminster Barracks.

Truex was hired in 1998 and assigned to the Rutland Barracks. He worked as a trooper at the Rutland and Shaftsbury barracks before becoming a detective trooper in Rutland in 2008, and then promoted to sergeant in 2010. In the Criminal Division, he has worked out of the Rutland Barracks and at Headquarters as a member of the Polygraph Unit. His current assignment is with the Major Crime Unit – South.

The Brattleboro Police Department member is identified as Patrol Officer Ryder Carbone, who has worked for the agency since 2019. He fired his department-issued shotgun during the encounter with Davis. Per standard protocol, Carbone is on paid administrative leave following the shooting.

As part of the ongoing, multi-state investigation into Anderson’s killing, police would like to speak to anyone in New England — especially Massachusetts, New Hampshire and Vermont — who might have seen Anderson, Davis, or Anderson’s truck from late Saturday night through early Tuesday morning. The vehicle is a blue 2017 Toyota Tacoma with Massachusetts license plate PC 8DXW20. Brattleboro police located the truck with Anderson’s body inside at about 12:55 a.m. Tuesday parked on Elliot Street in Brattleboro. Investigators are continuing to work to determine what if any connection Davis or Anderson might have had to Brattleboro.

According to media reports, On July 12, 2010, Davis appeared in court before Berkshire Superior Court Judge John A. Agostini and admitted to single counts of armed assault with intent to kill and entering without breaking in the nighttime. He served time at Northeast Correctional Center in Concord, Massachusetts until his parole in January 2015.

  1. The perp made his own bed. My heart goes out to the Police Officers who were put into a “you or me” situation. Unfortunately, because of the actions of this sick SOB, their memory will be saddled with this for the rest of their lives.

  2. Good thing it didn’t happen in Chittenden County. I’ll bet these two troopers would be on the rack for using “disproportionate force.” After all, if you’re attacked with a knife, wouldn’t progressive doctrine would say that you should defend yourself with a knife?

  3. I know both of the Troopers involved. I’m thankful that all three Officers were able to return home safe and sound to families.

  4. too stupid, threating the police is always a wrong decision.
    too often these violent offenders repeat and repeat and repeat their actions.
