Concerns When Using Examination
Gloves at the Crime Scene


David A. Lounsbury
L. Frank Thompson

From the Journal of Forensic Identification
Vol. 56, No. 2, March/April 2006*

Abstract: Universal precautions that are used by forensic personnel at crime scenes are necessary to protect the crime scene processors from chemical and biological hazards. These precautions also serve to ensure that the scene is not contaminated by actions of the crime scene examiners. A particular type of glove that is routinely used in crime scene processing does protect against hazards but is not effective against scene contamination.

Introduction
Most individuals who are involved in the processing and reconstruction of crime scenes and associated evidence understand the absolute necessity to protect their skin from coming in contact with items of physical evidence. Additionally, crime scene personnel must not contaminate evidence that is being recovered during the collection and examination phases of the crime scene processing. For these reasons, gloves must be worn. However, many crime scene technicians and investigators have the misconception that gloves will prevent fingerprints from being left on handled items. Saferstein recommends that crime scene processors wear two pairs of latex gloves as a minimum. This doubles the protection of both biohazard transmission and evidence contamination. Gerberth states that “approved disposable gloves” should be used at the crime scene. Lee recommends latex gloves for the handling of evidence that is located in crime scenes. Although latex gloves are often referred to in crime scene manuals and texts, some authors explain that liquid barrier rubber gloves are preferred.

Although the majority of texts recommend the use of latex gloves at the crime scene, latex presents a medical problem for some. Latex allergies are a danger to an increasing number of individuals. This requires the selection of other gloves, most of which come from the medical profession. Various nitrile, latex, and vinyl examination gloves are popular in most crime scene processing units.

Research
In July 2004, 28 criminal forensic studies students from Florida Gulf Coast University participated in an experiment involving medical examination gloves and their ability to inadvertently contaminate evidence at a crime scene. The study was approved by the University Institutional Review Board. Medical verification was established to determine that none of the participants were allergic to any of the glove materials in the study. Allergies to latex were of particular concern.

Procedure
The participants were divided into four groups of seven each. Each group wore one of four types of popular examination gloves that are used by local crime scene units in South Florida (Fisherbrand Nitrile Examination Glove Catalog # 19-050-221D, Kimberly-Clark Safeskin Purple Nitrile Glove #50603, Oak Laboratory Handies Vinyl Gloves Item # 96-282, Ultra One Microf lex Powder-Free Latex Gloves #UL-315-L).

The authors (wearing cotton gloves) placed a single glove on the right hand of each participant, and then a paper bag was placed over the gloved hand. (The bag prevented the individual from contaminating the outside surface of the glove during the experiment.)

<9/11 victims identified from new DNA finds>
A fresh effort to identify victims of the 9/11 attacks on the World Trade Centre is under way in New York following the discovery of fragments of human remains in the area around Ground Zero. So far a handful of people whose remains were not found in the initial trawl through the rubble have been identified. But forensic scientists hope that when DNA identification begins in earnest more victims will be found, scientists at the annual meeting of the American Academy of Forensic Sciences in Washington DC were told on Saturday.

<Regional crime lab would help towns crack cases>
Inside the The Mat laundry at 360 Cumberland Ave., Portland, forensic evidence technician Victor Cote is dusting for fingerprints, footprints and checking all possible traces of evidence that may lead him to the suspects who attempted to break in to the business the night before. With a black brush, Cote applies a fine black-carbon dust to a door that was busted in, its lock smashed in a failed attempt to access the safe behind it. The carbon dust reveals a footprint where the perpetrator kicked in the door. Cote presses clear tape over the footprint, removing the tape and pressing it onto a piece of forensic paper, revealing the markings of a shoe print.

<Investigators learn how to study blood patterns at crime scenes>
Blood tells a story. In a small room in Edmonds a pool of blood on the floor and red smears on a table appear to weave a violent tale. Crimson droplets stain a wall and a trail leads out the door. No one is in the chair facing a table laden with booze bottles, playing cards and money. No one is there to tell detectives what happened. Bothell police officer Dan Christman, a blood pattern expert, asks investigators to take a closer look.

<Patricia Cornwell Spends $250,000 Proclaiming Respect for Cops>
A week after donating $1 million to New York's John Jay College of Criminal Justice to fund courses in crime-scene investigation, bestselling mystery novelist Patricia Cornwell has spent a further $250,000 on full-page newspaper ads to reassure police officers that she likes them. Cornwell told the Associated Press last week that she had made the donation after having seen "cops walk through blood'' and "leave their own fingerprints on a window.'' The ads, which appeared on Friday in the New York Times, the Washington Post and USA Today, read, in part, "What has been publicized certainly does not accurately reflect my deep respect and admiration for these hardworking law enforcement professionals.'' Cornwell now says her comments to the AP were directed at the general public, not the police. "What I was appalled by was what I've seen citizens do, not the police,'' Cornwell said when reached by phone.

<Cornwell Gives $1 Million for CSI in NYC>
Patricia Cornwell is donating $1 million to a top criminal justice college for a new academy to teach CSI techniques. The best-selling novelist said she's taking action because she's appalled by what she's seen at crime scene investigations. "I've seen cops walk through blood. I've seen them leave their own fingerprints on a window," Cornwell said in an interview Friday. "I've seen bloody clothing put in a plastic bag, instead of a paper bag, so it decomposes." Her funding will help start the Crime Scene Academy at New York's John Jay College of Criminal Justice, set to open this fall with training in DNA typing, fingerprint enhancement techniques, ballistics and forensic psychology.
