The Municipal Police Institute, Inc. (MPI) is a private, nonprofit charitable affiliate of the
Massachusetts Chiefs of Police Association. MPI provides training and model policies and
procedures for police agencies. This policy is an edited version of MPI Policy 2.14, “Vehicle
Fires.”
GENERAL CONSIDERATIONS AND GUIDELINES
The Lexington Fire Department and the Massachusetts State Fire Marshal’s Office are
the primary investigators when dealing with a fire or explosion within the Town of
Lexington. Although the Fire Department is the public agency responsible for the
handling of fires the police also have an important part to play. After the flames of a
burning motor vehicle are extinguished, the cause of such fire has to be determined.
When a fire or explosion destroys or damages property, the Fire Department may
initiate an investigation to determine if "carelessness or design" caused the fire or
explosion. Often times the Police Department will assist fire personnel in the
accomplishment of these goals. When an investigation seeks to determine the cause
of a fire, investigators must adhere to Fourth Amendment standards. The process of
determining the cause of such fire lends itself to certain search and seizure issues such
as:
• Whether a vehicle may be impounded pending the issuance of a search
warrant to determine the cause of said fire;
• Should a criminal or administrative search warrant be sought; and
• Does the warrant type affect the scope of a search?
It is the policy of the Lexington Police Department to:
Cooperate fully and impartially with statutory authorities whose responsibility
is to determine the cause and nature of motor vehicle fires.
M.G.L.A. c. 148 s. 2 states that: “heads of fire departments in cities, towns or
fire districts shall investigate the cause and circumstances of every fire or
explosion in their respective jurisdictions by which property has been
destroyed or damaged, especially to ascertain whether it was by
carelessness or design.”

Policy & Procedure Page 2 of 5
Maintain an investigative partnership between the Fire Department and the
Police Department, taking advantage of the technical skills of fire
investigators and the criminal investigative skills of police officers.
PROCEDURES
A. Definitions
Fire Investigator: A member of the Lexington Police Department who generally
has investigatory skills that can be used to compliment the technical knowledge
of Fire Department investigators. The Chief of Police will appoint one or more
police officers to act as fire investigators for the purpose of investigating fires.
B. Duties of Preliminary Officer at the Scene
1. The first arriving officers at a vehicle fire must insure the safety of its
occupants and safety of the public in the immediate area.
2. If a police officer arrives before the Fire Department he/she should
consider the use of the fire extinguisher, if it is safe to do so.
3. Officers should be aware of safety concerns that arise from car fires,
(although not a complete list), these are a few of the areas officers should
be aware of:
a. The ability of vehicles to become quickly engulfed with flames
and/or explode
b. The concerns of visibility impairment to other vehicles due to
excessive smoke,
c. Inhalation issues caused by smoke
d. The need to shut down the roadway to enhance safety,
e. Crowd control, and
f. The possibility that the vehicle could roll.
4. If the Fire Department is on scene, the officer’s primary duties will be the
controlling of traffic and assisting fire personnel at the scene.
5. After a vehicle fire has been extinguished, the officer on the scene should
speak with fire personnel as soon as practicable and obtain a better
understanding of the cause.
6. If the fire appears suspicious in any manner, the Commanding Officer
should be notified and a trained fire investigator should be dispatched to
the scene.
7. Officers should follow guidelines consistent with their training regarding
scene preservation.

C. Impounding the Motor Vehicle
1. In order to prevent unauthorized access to the vehicle after a suspicious
fire, fire investigators have authority to impound the vehicle prior to
obtaining the appropriate search warrant despite the owner's request that
the vehicle be towed to a location of his/her choice.i The Department
may post an officer to act as a guard at the location of the vehicle in order
to prevent unauthorized access while a warrant is being obtained.
2. If a vehicle is impounded, the fire investigators should immediately begin
the process of applying for either an administrative search warrant or a
criminal search warrant. This process should be completed as soon as
possible.
3. If exigent circumstances are present, such as if it appears that the
impounded vehicle could contain evidence easily lost or destroyed
despite its impoundment, investigators shall conduct a brief, immediate
search in order to recover such evidence.ii Fire investigators shall then
obtain an appropriate warrant to conduct a detailed examination of the
automobile where an extended period of time will lapse before
commencement of the examination.
D. Obtaining the Appropriate Search Warrant
1. Administrative Search Warrants
a. If the fire investigator does not have probable cause to believe that
the fire was intentionally set, or that the vehicle contains evidence
of a crime, [s]he may nonetheless apply for an administrative
search warrant in order to determine the cause and origin of the
fire.iii For example, if there is no information that the vehicle is
stolen and there is no probable cause to believe that the vehicle
contains evidence of a crime or was intentionally set on fire, then
an investigator should seek an administrative search warrant.
b. The scope of an administrative search warrant is narrower than
that of the criminal search warrant, being limited to seeking
evidence of whether carelessness or design caused the fire or
explosion.
c. An administrative search warrant does not authorize a fire
investigator to conduct a general search for evidence of a crime.
For example, a fire investigator may not examine the ignition to
determine if it has been defeated or search for identification
evidence.
d. Evidence of a crime in plain view, may be seized. This may
include evidence of a crime other than arson (e.g., weapons,
contraband, drugs, etc.). However, any additional search for
evidence of such crimes (even identification evidence such as
fingerprints) must be done pursuant to a criminal search warrant.

e. If while conducting an administrative search, an investigator
makes plain view observations and accumulates enough
evidence to establish probable cause to believe that the fire was
intentionally set or the vehicle was stolen (e.g., evidence of forced
entry or tampered ignition), [s]he should immediately suspend the
administrative search and apply for a criminal search warrant.
2. Criminal Search Warrants
a. If a fire investigator has probable cause to believe that a fire was
intentionally set and/or there would be evidence of a crime within
a vehicle, [s]he should apply for a criminal search warrant before
searching for evidence of a crime.
b. Probable cause to believe that the fire was intentionally set may
arise from observations of the fire fighters or the investigator and
from the facts surrounding the fire itself. For example, if the fire
was inside the vehicle's passenger compartment (as opposed to
under the hood); if the firefighters detected the presence of
accelerants inside the compartment; and/or if the seat cushions
were burned more extensively than the rest of the automobile, a
criminal search warrant to search for evidence of arson should be
sought.
c. A criminal search warrant should be sought when the investigator
has probable cause to believe that a vehicle is evidence of another
crime. For example, the owner may have reported the vehicle
stolen prior to the fire, or a witness may have identified the vehicle
as being used during the commission of a crime.
i. In such circumstances, the fire investigator should obtain a
criminal search warrant to examine the vehicle for evidence
of both the underlying crime and arson. For example, if the
owner has reported a vehicle stolen, the criminal search
warrant should allow the fire investigator to search for and
seize identification evidence (fingerprints, etc.), evidence
that the vehicle was stolen (examine the ignition to see if it
was defeated, etc.) and evidence of arson (presence of
accelerant, igniter, etc.).
ii. The fire investigator's affidavit should specify that, based on
his/her training and experience, [s]he has probable cause
to believe that whoever stole the vehicle or used it to
commit another crime, probably set fire to the vehicle
intentionally in order to destroy evidence.
iii. When considering whether to apply for a criminal search
warrant, a fire investigator should consider whether the
vehicle's owner might have reported it stolen and then
intentionally set it on fire in order to obtain insurance
money. A criminal search warrant authorizing a fire
42P-Vehicle Fires
Policy & Procedure Page 5 of 5
investigator to seize evidence that a vehicle was stolen and
purposely set ablaze could reveal that the vehicle was
intentionally set ablaze but not that it was stolen. For
example, the search may reveal that the ignition was not
defeated or tampered with. These facts might lead to the
conclusion that the owner was the arsonist.
d. A search warrant need not be obtained if the owner consents to
the search of the vehicle to determine the cause or for evidence
of arson and for evidence of any other crimes.
E. Checklist After Suspicious Vehicle Fires
1. After the fire is extinguished, immediately make a brief examination of
the vehicle and remove any evidence in plain view that may be lost or
destroyed during the impound, pending further investigation.
2. Impound vehicle.
3. Determine if probable cause exists to indicate that a crime has been
committed or the vehicle contains evidence of a crime.
4. If no probable cause exists, the applications for an administrative search
warrant may be sought to determine carelessness or design.
5. If during the execution of an administrative search warrant, probable
cause of a crime becomes evident, stop the search immediately and
apply for a criminal search warrant.
6. Execute the criminal search warrant and seize all evidence.
7. Refer any questions you may have to the Middlesex District Attorney's
Office.
