The Importance of Careful Interpretation
of Shell Casing Ejection Patterns
Erin Sims
Larry Barksdale
From the Journal of Forensic
Identification
Vol. 55, No. 6, November/December 2005*
Abstract: An experiment was conducted to gain
information about shell casing ejection patterns. The research project
showed that shell casing ejection patterns are dependent on a number of
variables: type of firearm, stance, hand and weapon position (grip), and movement.
Background
A review of the literature indicated some disparity in the opinions of
crime scene investigators concerning the position of casings related to
shooting incidents.
Ogle notes that the “location of fired
cartridge cases may be valuable in a reconstruction attempt of the shooting
incident. The location(s) of the shooter(s) may be determined by the
analysis of the locations of the fired cases”. Gardner writes that firearms
examiners conduct, on occasion, ejection studies with the purpose of determining
the distance and direction that a casing will eject when the weapon is held
in any given orientation. He continues by noting that ejection studies have
limited value, because casings will roll when they hit the ground or
ricochet from walls or objects.
Garrison conducted a study on the
position of casings dropped from a moving vehicle. He posited that some of
the variables that can affect the final location of ejected casings are
speed, road surfaces, vehicular traffic, crowds that might move the casings,
and cartridge types. One of his observations was that, under similar
circumstances, rimmed casings tend to travel less distance. Other research
suggests that depending on many variables, extracted casings can end up
virtually anywhere.
Case History
A patrol officer observed a black Cadillac with expired license plates
driving on the city streets. The officer attempted to initiate a traffic
stop. The vehicle fled, the officer began to pursue the vehicle and, within
a few seconds, the suspect lost control of the Cadillac, which jumped a
curb and came to rest in the yard of a residential neighborhood. The
officer stopped behind the vehicle and exited his cruiser to make contact
with the driver. The suspect exited his vehicle and fired two shots from a
handgun. The officer took cover between the two vehicles and returned fire.
(The officer later said that he thought he had fired his weapon four
times.) The suspect then ran from the scene, entered a trailer park,
turned, and fired three more shots in the direction of the officer. The
officer radioed for assistance. A second officer observed a person matching
the suspect’s physical description running through the trailer park. The
second officer ide! ntified himself, ordered the suspect to stop, and gave
foot chase. The suspect was subsequently taken into custody, and was later
identified by the initial officer. Neither the suspect nor the officer was
injured during the shooting. The suspect was intoxicated, had narcotics on
his person, and had six live .357 caliber rounds in his pocket. During a
search of the area, a .357 caliber Ruger 6-shot revolver was located on the
ground between the initiating officer’s cruiser and the location of arrest.
One live round and five spent shell casings were located inside this
handgun.

<DNA Technology Moves Forward>
When the Maryland State Police lab told her that the evidence didn't contain
enough bodily fluid for a complete DNA profile, Shelly Progovitz was crushed.
A man who had brutally raped a 12-year-old girl behind a middle school in
Waldorf in 1996 and then tied her hands and feet and forced a sock into her
mouth would never be convicted for what he had done. But Progovitz, a crime
scene technician, did not let her disappointment keep her on the sidelines
long. That night, she went home and searched on Google for something she had
read about in scientific journals but had never used: "touch DNA."

<CSI Winona: Evidence collection in city not as
glamorous as TV, but still compelling>
They are not nearly as glamorous, exciting or flashy as the ones on
television show, “CSI: Crime Scene Investigation,” and its spin-offs, but the
Winona crime lab and evidence rooms offer their own quirks and crime-solving
drama.Winona Police Investigator Angie Evans speaks to classes on a regular
basis and finds that about 90 percent of people have seen the show, most of
whom by now have preconceived notions about collecting evidence. She prefaces
every presentation with a warning that she’s never watched a minute of it and
won’t. It’s just not accurate, she says.

<Long Island gets federal grant to fund DNA labs>
Suspects on Long Island could be matched to crimes soo! ner - or be
exonerated quicker - with more than $500,000 in federal gr ant money that
will help fund police DNA laboratories, officials announced yesterday. The
funding - $245,794 for Nassau and $280,905 for Suffolk - must be used to
lessen turnaround times to analyze DNA samples and reduce backlogs, according
to the federal Department of Justice. In Nassau, the money will help purchase
a host of state-of-the-art equipment, including a machine to make a minuscule
DNA sample - such as blood, semen and saliva - easier to analyze. It will
also fund upgrades to a computerized, paperless case-record system that went
online this summer, said Pasquale Buffolino, the director of the county's
Department of Forensic Genetics. The number of cases Buffolino's lab handles
has risen steadily. In 2005, for example, the lab accepted 415 cases. Last
year, the lab accepted 654.

<Building better crime labs: Improvements to
facilities allow cities to meet demand for forensic analysis>
Valley crime labs are growing to keep pace with the ever-increasing demand
for forensic evidence.Mesa opens a state-of-the art lab next month, Chandler
is planning a new one, Phoenix opened a new lab in June 2007, and Scottsdale
plans to open a new lab next September. "Success breeds more work,"
said Todd Griffith, scientific-analysis superintendent for the state
Department of Public Safety. "There's more we can do with the
evidence." He said 11 new technicians recently finished training at the
DPS lab and the additional personnel would help cut into a backlog of DNA
cases. Steve Garrett, Scottsdale's forensic-services division manager, said
detectives used to be more selective by requesting analysis for only major
violent crimes such as homicides and sexual assaults. But now forensic work
is performed on more routine crimes that affect more people,! such as
burglaries and auto thefts.

<Flames ruin clues with a chilling efficiency>
Whoever shot to death three women and a girl in an Irvington house last week
finished the crime with a devastating coda: torching the place. Fire is one
of the worst things that can happen to a murder scene, investigators say. The
heat, which can climb well above 1,000 degrees, can incinerate fingerprints,
hair, blood and any biological evidence that could yield a DNA profile of the
killer. Bullets and shell casings can warp, making it hard to trace a gun.
Firefighters, trying to put out the blaze, douse the scene with water and
chemicals, wrecking things further. "It makes your job a lot harder when
you get that kind of damage," said Detective Sgt. First Class Howard
Ryan, a veteran State Police crime scene investigator. "I'm not saying
you can't find things,! but it makes it a lot more difficult."
