learn more about the integrated ballistics identification system so why
ballistics identification system so why
ballistics identification system so why do we start by having you tell us what
do we start by having you tell us what
do we start by having you tell us what is Ibis one of these is a machine that’s
is Ibis one of these is a machine that’s
is Ibis one of these is a machine that’s used to photograph the markings on
used to photograph the markings on
used to photograph the markings on bullets and cartridge cases after
bullets and cartridge cases after
bullets and cartridge cases after they’ve been fired through a gun they
they’ve been fired through a gun they
they’ve been fired through a gun they actually end up with a unique pattern of
actually end up with a unique pattern of
actually end up with a unique pattern of scratches on variations that will repeat
scratches on variations that will repeat
scratches on variations that will repeat from firearm to firearm but are always
from firearm to firearm but are always
from firearm to firearm but are always unique how does the system affect
unique how does the system affect
unique how does the system affect investigations today traditionally it’s
investigations today traditionally it’s
investigations today traditionally it’s the detectives that actually come back
the detectives that actually come back
the detectives that actually come back to the farms examiner and say there was
to the farms examiner and say there was
to the farms examiner and say there was a shooting last night it seems like it
a shooting last night it seems like it
a shooting last night it seems like it was this guy who did it we got his gun
was this guy who did it we got his gun
was this guy who did it we got his gun is this the gun that did it they might
is this the gun that did it they might
is this the gun that did it they might not get a match off of that crime scene
not get a match off of that crime scene
not get a match off of that crime scene but now both those pieces of evidence
but now both those pieces of evidence
but now both those pieces of evidence are in the system it won’t forget and
are in the system it won’t forget and
are in the system it won’t forget and any amount of time later it might come
any amount of time later it might come
any amount of time later it might come up with a hit and the farm’s examiner
up with a hit and the farm’s examiner
up with a hit and the farm’s examiner and call the detective up and say
and call the detective up and say
and call the detective up and say remember that crime scene from two
remember that crime scene from two
remember that crime scene from two months ago that we didn’t have it in for
months ago that we didn’t have it in for
months ago that we didn’t have it in for you the gun was just used again in a
you the gun was just used again in a
you the gun was just used again in a bank robbery last night would you be
bank robbery last night would you be
bank robbery last night would you be able to show us some of the defining
able to show us some of the defining
able to show us some of the defining characteristics of a bullet in a casing
characteristics of a bullet in a casing
characteristics of a bullet in a casing yeah absolutely so your cartridge has
yeah absolutely so your cartridge has
yeah absolutely so your cartridge has got four main components your bullet the
got four main components your bullet the
got four main components your bullet the cartridge case itself the primer on the
cartridge case itself the primer on the
cartridge case itself the primer on the back and gunpowder on the inside during
back and gunpowder on the inside during
back and gunpowder on the inside during the firing sequence what happens is the
the firing sequence what happens is the
the firing sequence what happens is the firing pin of the firearm strikes the
firing pin of the firearm strikes the
firing pin of the firearm strikes the primer which causes the spark inside the
primer which causes the spark inside the
primer which causes the spark inside the spark makes the powder burn which builds
spark makes the powder burn which builds
spark makes the powder burn which builds a pressure and causes the bullet to go
a pressure and causes the bullet to go
a pressure and causes the bullet to go down the barrel the rifling marks inside
down the barrel the rifling marks inside
down the barrel the rifling marks inside the barrel that cause the bullet to
the barrel that cause the bullet to
the barrel that cause the bullet to twist are actually dragged across the
twist are actually dragged across the
twist are actually dragged across the surface of the bullet and so you get
surface of the bullet and so you get
surface of the bullet and so you get these channels these grooves basically
these channels these grooves basically
these channels these grooves basically that have a unique pattern of Shriya all
that have a unique pattern of Shriya all
that have a unique pattern of Shriya all the way around all that pressure to push
the way around all that pressure to push
the way around all that pressure to push the bullet down the barrel equal and
the bullet down the barrel equal and
the bullet down the barrel equal and opposite reaction pushes that cartridge
opposite reaction pushes that cartridge
opposite reaction pushes that cartridge case straight into the breech wall and
case straight into the breech wall and
case straight into the breech wall and so whatever pattern is on that wall got
so whatever pattern is on that wall got
so whatever pattern is on that wall got stamped across the surface of the
stamped across the surface of the
stamped across the surface of the cartridge case and those are two areas
cartridge case and those are two areas
cartridge case and those are two areas there on the bullet as well as on the
there on the bullet as well as on the
there on the bullet as well as on the cartridge case and giving you a neat
cartridge case and giving you a neat
cartridge case and giving you a neat pattern that that will reproduce from
pattern that that will reproduce from
pattern that that will reproduce from shot to shot the machine we’re looking
shot to shot the machine we’re looking
shot to shot the machine we’re looking at here is called bullet tracks it’s
at here is called bullet tracks it’s
at here is called bullet tracks it’s used to do a 3d topographical scan of
used to do a 3d topographical scan of
used to do a 3d topographical scan of the markings on the bullets surface you
the markings on the bullets surface you
the markings on the bullets surface you mount the bullet underneath the sensor
mount the bullet underneath the sensor
mount the bullet underneath the sensor and it’ll be rotated 360 degrees around
and it’ll be rotated 360 degrees around
and it’ll be rotated 360 degrees around while the actual sensor is capturing the
while the actual sensor is capturing the
while the actual sensor is capturing the surface topography as that
surface topography as that
surface topography as that light shines across you can even still

light shines across you can even still make out that strident pattern it’s
make out that strident pattern it’s
make out that strident pattern it’s doing an in-depth scan right now so now
doing an in-depth scan right now so now
doing an in-depth scan right now so now with the acquisition completed over here
with the acquisition completed over here
with the acquisition completed over here what we’ll do is a cartridge case
what we’ll do is a cartridge case
what we’ll do is a cartridge case acquisition on the rash tracks machine
acquisition on the rash tracks machine
acquisition on the rash tracks machine so the machine we’re looking at here is
so the machine we’re looking at here is
so the machine we’re looking at here is called brass tracks and it’s used to
called brass tracks and it’s used to
called brass tracks and it’s used to photograph the markings on the head of
photograph the markings on the head of
photograph the markings on the head of the cartridge case we’re going to take
the cartridge case we’re going to take
the cartridge case we’re going to take photographs of the breech face marks on
photographs of the breech face marks on
photographs of the breech face marks on the primer we’re going to do a close-up
the primer we’re going to do a close-up
the primer we’re going to do a close-up of the firing pin impression as well and
of the firing pin impression as well and
of the firing pin impression as well and we’re also going to do a close-up of the
we’re also going to do a close-up of the
we’re also going to do a close-up of the ejector mark on the side on this
ejector mark on the side on this
ejector mark on the side on this cartridge case you’ve got the silver
cartridge case you’ve got the silver
cartridge case you’ve got the silver disc on the back of it we’re going to do
disc on the back of it we’re going to do
disc on the back of it we’re going to do some photographs of that silver disc the
some photographs of that silver disc the
some photographs of that silver disc the primer so we’ll do that right now
what it’s going to do now is what we
what it’s going to do now is what we call the full head stamp it’s going to
call the full head stamp it’s going to
call the full head stamp it’s going to take a series of nine photographs which
take a series of nine photographs which
take a series of nine photographs which it will then reconstruct into one giant
it will then reconstruct into one giant
it will then reconstruct into one giant image that’s about the entire head of
image that’s about the entire head of
image that’s about the entire head of the cartridge case in one giant photo so
the cartridge case in one giant photo so
the cartridge case in one giant photo so what we’re looking at now is a close-up
what we’re looking at now is a close-up
what we’re looking at now is a close-up of the breech face information all the
of the breech face information all the
of the breech face information all the striations that were marked on that
striations that were marked on that
striations that were marked on that breech base it was photographed we’re
breech base it was photographed we’re
breech base it was photographed we’re able to look at them side by side and
able to look at them side by side and
able to look at them side by side and move the hairline back and forth to see
move the hairline back and forth to see
move the hairline back and forth to see how much is common between the reference
how much is common between the reference
how much is common between the reference exhibit and the test one here’s your
exhibit and the test one here’s your
exhibit and the test one here’s your reference this is a guy that was
reference this is a guy that was
reference this is a guy that was standard during the correlation and this

standard during the correlation and this is a guy that was in the database that
is a guy that was in the database that
is a guy that was in the database that came up as the best potential match and
came up as the best potential match and
came up as the best potential match and already the naked eye you’ve got a lot
already the naked eye you’ve got a lot
already the naked eye you’ve got a lot of similarities here with the within the
of similarities here with the within the
of similarities here with the within the shear marks also the striations on the
shear marks also the striations on the
shear marks also the striations on the surface you can see with the ring light
surface you can see with the ring light
surface you can see with the ring light image that we’re looking at there’s some
image that we’re looking at there’s some
image that we’re looking at there’s some common details between the two so we’re
common details between the two so we’re
common details between the two so we’re going to look at now is the correlation
going to look at now is the correlation
going to look at now is the correlation results two bullet score so what we want
results two bullet score so what we want
results two bullet score so what we want to do now is see how much common
to do now is see how much common
to do now is see how much common information there is between these two
information there is between these two
information there is between these two exhibits by sliding them together and
exhibits by sliding them together and
exhibits by sliding them together and also by moving that hairline back and
also by moving that hairline back and
also by moving that hairline back and forth

forth it’s what the tracks machines are
it’s what the tracks machines are
it’s what the tracks machines are enabling farms examiner’s to do now in
enabling farms examiner’s to do now in
enabling farms examiner’s to do now in the crime lab is to scan through
