Instruction 9.160, Criminal Model Jury Instructions for Use in the District Court
Identification
MODEL EYEWITNESS IDENTIFICATION INSTRUCTION
This instruction should be given in any case in which the jury heard eyewitness evidence that
positively identified the defendant and in which the identification of the defendant as the person who
com m itted or participated in the alleged crim e(s) is contested. W here there is no positive
identification but a partial identification of the defendant, as discussed in Commonwealth v. Franklin,
465 Mass. 895, 910-12 (2013), this instruction or “som e variation” of it should be given upon
request. The instruction is set forth at 473 Mass. 1051 (2015).
The Commonwealth has the burden of proving beyond a reasonable
doubt that the defendant is the person who committed (or participated in)
the alleged crime(s). If you are not convinced beyond a reasonable doubt
that the defendant is the person who committed (or participated in) the
alleged crime(s), you must find the defendant not guilty.
Where a witness has identified the defendant as the person who
committed (or participated in) the alleged crime(s), you should examine the
identification with care. As with any witness, you must determine the
witness’s credibility, that is, do you believe the witness is being honest?
Even if you are convinced that the witness believes his or her identification
is correct, you still must consider the possibility that the witness made a
mistake in the identification. A witness may honestly believe he or she saw
a person, but perceive or remember the event inaccurately. You must
1. Opportunity to view the event.
decide whether the witness’s identification is not only truthful, but accurate.
People have the ability to recognize others they have seen and to
accurately identify them at a later time, but research and experience have
shown that people sometimes make mistakes in identification.
The mind does not work like a video recorder. A person cannot just
replay a mental recording to remember what happened. Memory and
perception are much more complicated. Remembering something requires
i
three steps. First, a person sees an event. Second, the person’s mind
stores information about the event. Third, the person recalls stored
information. At each of these stages, a variety of factors may affect — or
even alter — someone’s memory of what happened and thereby affect the
accuracy of identification testimony. This can happen without
ii
the witness
being aware of it.
I am going to list some factors that you should consider in
determining whether identification testimony is accurate.
You should consider the opportunity
the witness had to observe the alleged offender at the time of the event.
For example, how good a look did the witness get of the person and for
how long? How much attention was the witness paying to the person at
that time? How far apart were the witness and the person? How good
were the lighting conditions? You should evaluate a witness’s testimony
about his or her opportunity to observe the event with care.iii
a. If there was evidence that a disguise was involved or the alleged offender’s
face was obscured.
You should consider whether the person was disguised or had
his or her facial features obscured. For example, if the person
wore a hat, mask, or sunglasses, it may affect the witness’s
ability to accurately identify the person.iv
b. If there was evidence that the alleged offender had a distinctive face or feature.
You should consider whether the person had a distinctive face
or feature.v
You should consider
c. If there was evidence that a weapon was involved.
whether the witness saw a weapon during the event. If the
event is of short duration, the visible presence of a weapon may
distract the witness’s attention away from the person’s face.
But the longer the event, the more time the witness may have to
get used to the presence of a weapon and focus on the person’s
face.vi
2. Characteristics of the witness.
You should consider the physical and
mental characteristics of the witness when the observation was made. For
example, how good was the witness’s eyesight? Was the witness
experiencing illness, injury, or fatigue? Was the witness under a high level
of stress? High levels of stress may reduce a person’s ability to make an
accurate identification.vii
a. If there was evidence that the witness and the person identified are family
members, friends, or longtime acquaintances.
If the person identified is a witness’s family member, friend, or
longtime acquaintance, you should consider the witness’s prior
familiarity with the person.viii
You should
b. If there was evidence that drugs or alcohol were involved.
consider whether, at the time of the observation, the witness
was under the influence of alcohol or drugs and, if so, to what
degree.
3. Cross-racial identification.
4. Passage of time.
5. Expressed certainty.
Omit the following instruction only if all parties agree that there was no cross-racial identification.
The trial judge has the discretion to add the references to ethnicity to the instruction. See
Commonwealth v. Bastaldo, 472 Mass. 16, 29-30 (2015).
If the witness and the person
identified appear to be of different races (or ethnicities), you should
consider that people may have greater difficulty in accurately identifying
someone of a different race (or ethnicity) than someone of their own race
(or ethnicity).ix
You should consider how much time passed
between the event observed and the identification. Generally, memory is
most accurate immediately after the event and begins to fade soon
thereafter.x
You may consider a witness’s identification
even where the witness is not free from doubt regarding its accuracy. But
you also should consider that a witness’s expressed certainty in an
identification, standing alone, may not be a reliable indicator of the
accuracy of the identification, especially where the witness did not

describe that level of certainty when the witness first made the
identification.xii
You should consider that the
accuracy of identification testimony may be affected by information that the
witness received between the event and the identification,
or received
xiii
after the identification.
Such information may include identifications
xiv
made by other witnesses, physical descriptions given by other witnesses,
photographs or media accounts, or any other information that may affect
the independence or accuracy of a witness’s identification. Exposure to
xv
such information not only may affect the accuracy of an identification, but
also may affect the witness’s certainty in the identification and the
witness’s memory about the quality of his or her opportunity to view the
event.
The witness may not realize that his or her memory has been
xvi
affected by this information.xvii
An identification made after suggestive conduct by the police or
others should be scrutinized with great care. Suggestive conduct may
include anything that a person says or does that might influence the
witness to identify a particular individual.
Suggestive conduct need not

be intentional, and the person doing the “suggesting” may not realize that
he or she is doing anything suggestive.xix
An identification
a. If there was evidence of a photographic array or a lineup.
may occur through an identification procedure conducted by
police, which involves showing the witness a (set of
photographs) (lineup of individuals). Where a witness identified
the defendant from a (set of photographs) (lineup), you should
consider all of the factors I have already described about a
witness’s perception and memory. You also should consider
the number of (photographs shown) (individuals in the lineup),
whether anything about the defendant’s (photograph) (physical
appearance in the lineup) made the defendant stand out from
the others, whether the person (showing the photographs)
xx
(presenting the lineup) knew who was the suspect and could
have, even inadvertently, influenced the identification,
and
xxi
whether anything was said to the witness that may have
influenced the identification.
You should consider that an
xxii
identification made by picking a defendant out of a group of
similar individuals is generally less suggestive than one that
results from the presentation of a defendant alone to a witness.
b. Upon request, the judge should also give an instruction about the source
of the defendant’s photograph within the array.
You have heard that the police showed the witness a number of
photographs. The police have photographs of people from a
variety of sources, including the Registry of Motor Vehicles.
You should not make any negative inference from the fact that
the police had a photograph of the defendant.
An identification may occur
c. If there was evidence of a showup.
through an identification procedure conducted by police known
as a showup, in which only one person is shown to a witness.
A showup is more suggestive than asking a witness to select a
person from a group of similar individuals, because in a showup
only one individual is shown and the witness may believe that
the police consider that individual to be a potential suspect.
xxiii
You should consider how much time has passed between the
event and the showup because the risk of an inaccurate
identification arising from the inherently suggestive nature of a
showup generally increases as time passes.xxiv
You should
d. If there was evidence of a photographic array, lineup, or showup.
consider whether the police, in showing the witness (a set of
photographs) (a lineup) (a showup), followed protocols
established or recommended by the Supreme Judicial Court or
the law enforcement agency conducting the identification
procedure that are designed to diminish the risk of suggestion.
If any of those protocols were not followed, you should evaluate
the identification with particular care.
The trial judge may take judicial notice of police protocols regarding eyewitness identification that
have been established or recommended by the Supreme Judicial Court, and include in the
instruction those established or recommended protocols that are relevant to the evidence in the
case. See Commonwealth v. Walker, 460 Mass. 590, 604 (2011) (“Unless there are exigent or
extraordinary circumstances, the police should not show an eyewitness a photographic array. . .
that contains fewer than five fillers for every suspect photograph. . . . W e expect police to follow
our guidance to avoid this needless risk”); Commonwealth v. Silva-Santiago, 453 Mass. 782, 797-
98 (2009) (“W hat is practicable in nearly all circumstances is a protocol to be employed before a
photographic array is provided to an eyewitness, making clear to the eyewitness, at a minimum
that: he will be asked to view a set of photographs; the alleged wrongdoer may or may not be in
the photographs depicted in the array; it is just as important to clear a person from suspicion as to
identify a person as the wrongdoer; individuals depicted in the photographs may not appear
exactly as they did on the date of the incident because features such as weight and head and
facial hair are subject to change; regardless of whether an identification is made, the investigation
will continue; and the procedure requires the administrator to ask the witness to state, in his or her
own words, how certain he or she is of any identification”); id. at 798 (“W e decline at this time to
hold that the absence of any protocol or comparable warnings to the eyewitnesses requires that
the identifications be found inadmissible, but we expect such protocols to be used in the future”);
id. at 797 (“W e have yet to conclude that an identification procedure is unnecessarily suggestive
unless it is administered by a law enforcement officer who does not know the identity of the
suspect [double-blind procedure], recognizing that it may not be practicable in all situations. At
the same time, we acknowledge that it is the better practice [compared to a non-blind procedure]
because it eliminates the risk of conscious or unconscious suggestion”). If the Legislature were to
establish police protocols by statute, the judge should instruct the jury that they may consider

protocols established by the Legislature. The judge also may take judicial notice of those
protocols and include them in the instruction.
The trial judge also may include established or recommended procedures where the evidence
shows that they were established or recommended by the law enforcement agency conducting the
investigation at the time of the identification procedure.
e. If there was evidence of a multiple viewings of the defendant by
the same witness.
You should consider whether the witness viewed the defendant
in multiple identification procedures or events. When a witness
views the same person in more than one identification
procedure or event, it may be difficult to know whether a later
identification comes from the witness’s memory of the original
event, or from the witness’s observation of the person at an
earlier identification procedure or event.xxv
You should
consider whether a witness ever failed to identify the defendant, or made
an identification that was inconsistent with the identification that the
witness made at the trial.
In evaluating the accuracy of a witness’s
identification, you should consider all of the relevant factors that I have
discussed, in the context of the totality of the evidence in this case.
Specifically, you should consider whether there was other evidence in the
case that tends to support or to cast doubt upon the accuracy of an
identification. If you are not convinced beyond a reasonable doubt that the
defendant is the person who committed (or participated in) the alleged
crime(s), you must find the defendant not guilty.
