The Massachusetts State Police (MSP) is an agency of the Commonwealth of Massachusetts' Executive Office of Public Safety and Security responsible for criminal law enforcement and traffic vehicle regulation across the state. At present, it has approximately 2,300 officers, 1500 of them being uniformed troopers, and 400 civilian support staff—making it the largest law enforcement agency in New England. The MSP is headed by Colonel Richard McKeon.


It investigates instances of wrongful deaths in most Massachusetts cities.


The MSP was established by Governor John A. Andrew when he signed a law creating the State Constabulary on May 16, 1865. This legislative act to “establish a State Police Force,” founded the first statewide enforcement agency in the nation. The first leader of the State Police was a General King. His title was probably earned during the American Civil War. The agency remained small and rather informal until 1921, when the MSP was enlarged to comprise 50 officers stationed in barracks across the state with the primary mission of providing law enforcement to rural areas underserved by existing local police agencies. This law enforcement mission was performed by the trooper on horse back, usually, and in motor cars in areas with upgraded roads. The MSP enlarged its mission to handle primary vehicular regulation on the Commonwealth's interstate and limited-access highways after their development mid-century; during this period, it also established a presence in protecting Logan International Airport.

For much of the twentieth century, the MSP was organized along militaristic lines with a heavy emphasis on the role of the barracks, spartan working conditions, and a uniformity in appearance and internal culture. Until recently, the MSP maintained one of the strictest regimens for physical size requirements for applicants. Efforts are being made presently to render the department more racially diverse, as well as more inclusive of women and LGBT officers.

The history of the agency is being researched and preserved for the 2010 opening of the Massachusetts State Police Museum and Learning Center. The museum is being made possible by funding of MSP troopers and employees. The museum will be located at the site of the former Troop C2 barracks in Grafton. There is currently a temporary museum at the barracks until construction is completed. Planned exhibits for the museum are

  • Restored 1931, 1941, 1951 Ford Cruisers
  • Motorcycles, including a 1963 Harley Davidson
  • State Police Weapons (past & present)
  • Historical uniforms, hats and artifacts
  • Harvard riot photos and riot equipment
  • Mounted police equipment and other Equine related items
  • Original teletype machine
  • The first computer used by the State Police department
  • Historic daily station logs
  • President John F. Kennedy photos and memorabilia
  • Nostalgic badges and patches
  • Since the MSP's inception, 32 troopers have been killed in the line of duty. The earliest death was in 1909 and the latest death was March 16, 2016.

    Consolidation of state-controlled police agencies

    In 1992, the former Massachusetts Department of Public Safety - Division of State Police, Massachusetts Registry of Motor Vehicles Police, Massachusetts Capitol Police, and Metropolitan District Commission (MDC) Police (commonly known as the Metropolitan Police) departments merged to form what is currently known as the Department of State Police (an agency within the Executive Office of Public Safety, which is different from the Department of Public Safety). The four former agencies officially ceased to exist on July 1, 1992. The distinctive uniform and seal of the former Division of State Police would be retained by the newly formed Department of State Police. The ranks of Corporal and Staff Sergeant were not carried over into the new agency. The Massachusetts Environmental Police remained a separate entity under the Department of Fisheries, Wildlife, and Environmental Law Enforcement, until it became a separate department level office under the re-organised Executive Office of Energy and Environmental Affairs. As of late, there has been political debate concerning the state police merging with the MBTA Transit Police.

    Detective units

    The Commonwealth is divided into 11 State Police detective units that work out of various district attorneys' offices. Boston, Springfield, and Worcester are the only cities in the Commonwealth that have the authority to investigate homicides. This responsibility is granted through the District Attorney's Office in each city's respective county. According to Massachusetts General Law, all homicides are under the control of the District Attorney in the county they occur. Only the District Attorney can delegate the responsibility of investigating homicides to another party. In Springfield and Worcester, it is the captain in charge of the Detective Bureau, and in Boston, it is the commander of the Homicide Unit. The various district attorneys' offices investigate all other homicides in any other cities or towns. The detective units also investigate many other major crimes and serious incidents.

    Fire and Explosion Investigation Section

    Specially trained Massachusetts State Police detectives have functioned as State Fire Marshal investigators for more than fifty years. At present, the Fire & Explosion Investigative Section (F&EIS) consists of thirty-eight full-time members who make up the Fire Investigations and Hazardous Devices (Bomb Squad) units. F&EIS also consists of eight bomb techs, five bomb dogs and five accelerant detector dogs. Each unit has its own self-contained command and control structure and a specific jurisdiction to serve. Many of the investigators have been cross-trained to assist the other sections in time of need.

    Crime Lab

    The main Massachusetts State Police Crime Lab is located in Sudbury. There are several laboratory substations spread throughout the Commonwealth. The lab serves law enforcement agencies and District Attorneys throughout the Commonwealth, providing a wide array of support to facilitate effective investigations and criminal prosecutions. The Crime Lab examines evidence that can be used to help tie criminals to their crimes, victims to their assailants and exonerate innocent suspects. The Ballistics Section and Crime Scene Services Section are served by sworn personnel.

    The lab is broken up into sections and units:

  • Arson & Explosives Unit
  • Ballistics Section

  • Division of Standards & Training

    Recruit and in-service training for the Massachusetts State Police takes place at the MSP academy located centrally in Massachusetts at 340 West Brookfield Road in New Braintree. Prior to the 1992 merger, the Division of State Police's Training Academy was located in Framingham. This facility now houses the Department of State Police General Headquarters.

    Becoming a trooper is a competitive process. Approximately 14,000 men and women took the written entrance exam in June 2002. Out of that, only a few hundred were selected to become members of the MSP. After receiving a conditional job offer, the recruit has to make it through 21 weeks of paramilitary training as part of a Recruit Training Troop (RTT). As of April 2009, the State Police no longer administers its own standalone examination for appointment to the department. The State Police now generates a prospective list from candidates that take the Massachusetts Police Officer Civil Service examination who elect to be considered for appointment to the State Police; this is the same examination that is used by many municipal departments and the MBTA.

    On October 17, 2011, the 80th RTT began training. This was the first class in over five years. Training itself was dropped from the traditional 26 weeks to 21 weeks after new programs and exams were added that deal with current situations. During the 21 weeks of training the recruit lives at the academy Monday through Friday. The 80th RTT class began with 250 trainees, adding 25 trainees in the first two weeks of training as others departed the program. Their day starts at 5:30 a.m. and goes until 8 p.m. with lights out around 9:30. The recruits attend over 98 academic classes and must pass 10 cumulative exams with a passing score of 70%. Along with classes, recruits have to take part in daily physical regimens such as running and weight lifting. The 80th RTT graduated a record 208 new troopers on March 9, 2012.

    The academy takes a toll both mentally and physically on the recruit, and many recruits do not make it through. The typical academy washout rate is around 28-30%. For example, when the 77th RTT started in November 2004, there were 180 recruits. During the first week, 44 recruits dropped out and 34 new recruits had to be added in. By the end of the then 26 weeks, only 137 graduated.

    The academy also hosts the biannual Massachusetts State Police Student Trooper Program. The Student Trooper program is an intensive, one-week, residential learning experience for young adults, ages 15 thru 17.


    As of June 2000, the Massachusetts State Police had the following demographics:

  • Male: 91%
  • Female: 9%
  • White: 89%
  • African-American/Black: 11%
  • The MSP is one of the few State Police Departments in the US where the percentage of African American officers (11%) is significantly greater than that of the state population (6.97%).

  • Matt Damon plays a corrupt trooper who infiltrates the MSP for the Mob in The Departed (2006). Mark Wahlberg, Martin Sheen, Alec Baldwin, Anthony Anderson and Leonardo DiCaprio all portray troopers in the S.I.U. as well (DiCaprio as an undercover). Director Martin Scorsese asked the MSP if he could use actual logos, badges, and color schemes on the uniforms and the cruisers, but was denied.
  • Ben Benson's series of novels featuring Massachusetts State Troopers such as high ranking Chief of Detectives Wade Paris and rookie Trooper Ralph Lindsey, appearing mostly in the 1950s, were among the earliest examples of police procedurals.
  • When Benson died, another writer, Roy Stratton (the great-grandson-in-law of Charles Dickens) started a new series about the MSP for the same publisher, Mill-Morrow, featuring Trooper Scott Gregory; but the series ended after only two books.
  • The agency serves as a partial-setting for Dennis Lehane's novel Mystic River and its film version, in which the characters played by Kevin Bacon and Laurence Fishburne are MSP detectives.
  • The Robert B. Parker character Spenser is said to have been with the MSP, specifically as a detective with the Suffolk County District Attorney's office. He frequently interacts with an MSP homicide detective named Captain Healy (who also appears in the Jesse Stone novels) and worked with an MSP trooper named Brian Lundquist in the novel Pale Kings and Princes.
  • An MSP cruiser comes to a halt at the Wordloaf Conference in The Simpsons episode "Moe'N'a Lisa", having pursued the Simpsons into Vermont (minute 11:50 in the episode).
  • Norman Rockwell's famous painting The Runaway depicts a Massachusetts State Trooper and a young boy at a lunch counter. Rockwell lived in Massachusetts for much of his life. Actual MSP Trooper Dick Clemens is the Trooper portrayed in the painting. The boy's name is Edward Locke.
  • In Edge of Darkness, Ray Winstone's character is killed by a Massachusetts State Trooper.
  • In R.I.P.D., an MSP Air Wing helicopter takes part in the raid where Ryan Reynolds' character is killed.
  • In Patriots Day, an MSP trooper stands guard over Martin Richard's corpse until he can be taken away by ambulance, at which point he salutes. Other troopers appear sporadically throughout the film, and the commandant at the time Colonel Timothy Alben is a character in it portrayed by Charles Luise but is simply credited as "Massachusetts State Police Colonel."
