6 Don’ts of Crime Scene Laser Scanning

Documenting crime scenes is important and crucial business, and with technology advancing at such a rapid pace it is becoming easier to do. One advancement that has helped the documentation of crime scenes is that of laser scanning, a method of using lasers to digitally construct a three dimensional copy of the crime scene. Advances with this technology have made it even easier and more efficient to accurately document crime scenes while preserving the integrity of both the scene and the scan data. However, no method is perfect and provided in this article is a list, with thorough explanations, of six don’ts when it comes to using laser scanning technology to document your crime scene.

Touch DNA

DNA evidence is crucial when it comes to identifying suspects, victims, and whomever else is of interest in an investigation. Finding and retrieving this  evidence is a delicate process which requires technique and proper knowledge of retrieval in order to maintain the integrity of the evidence. This article provides the reader with steps to ensure the proper attainment of DNA evidence left behind by touch.

Thief’s Kiss Leads to DNA Evidence & Arrest

In an attempt to rob a jewelry store, two young thieves allegedly tied up, gagged, and threatened the owner of a Paris jewelry store after following her home. Out of frustration of the victim not cooperating, the thieves poured petrol over her head and threatened to set it alight if she did not provide the alarm codes for the jewelry store. Eventually the 56-year-old jeweler storeowner gave in and provided the alarm codes.

Hours later after the thieves cleaned out the store of all its precious jewels, one culprit returned to release the tied up woman. As a sign of compassion, the 20-year-old thief gave the victim a kiss on the cheek. This was indeed his biggest mistake!

DNA on the victim’s cheek was obtained and analyzed and forensic scientist at the scene swabbed the woman’s cheek to isolate the genetic profile. The thief’s DNA was identified and found to be on the National DNA Database. Months later the detectives discovered that the DNA matched a man who was being detained in Southern France on suspicion of other crimes. The alleged thief admitted to the crime and stated that he kissed the victim to “make up for the trauma”. The kissing bandit remains in custody while detectives trace his co-conspirator.

WVU offers Free Forensic Workshops for Middle & High School Students

The popular CBS television show CSI: Crime Scene Investigation, has manipulated the public into believing that crime scene evidence can be instantaneously analyzed, evaluated, and eventually linked to suspect; all within a 60 minute episode. This can be best described as the CSI effect.

Institutions across the United States want to bring the public back to reality from this fictional ideology, WVU is no acceptation. Charles Bily is an instructional coordinator with West Virginia University’s Next Generation Forensic Science Initiative, which is offering free workshops to both middle and school students. Fingerprints, Footwear impression evidence, Firearm identification, and Bloodstain pattern analysis workshops will each take place on February 22, March 22, April 26, and May 24, at West Virginia University’s Crime Scene Complex. Students who attend these workshops will learn both the process and value of lifting fingerprints and footwear impression; the importance of ammunition in firearms identification, and how to interpret bloodstain patterns at a crime scene.

Bily stated that it is a “really neat experience for the kids to take classes in that complex because that normally is reserved for the forensic science majors, So this is an opportunity for kids that don’t go to school here to get some experience in that complex.” Workshops are one and a half hour long, limited to a maximum enrollment of 25 students and are filled on a first-come, first served basis.

Collecting Footwear and Tire Impressions in Snow

On March 1, 2014, Lesley Hammer, a Forensic Footwear Examiner and Senior Crime Scene Analyst at the State of Alaska Crime Lab, and James Wolfe, a Police Instructor and adjunct faculty member for the University of Alaska, will host a LIVE stream presentation entitled “Collecting Footwear and Tire Impressions in Snow” which will contain vital information helpful to Evidence Collectors, Law Enforcement Officers, and Forensic Professionals.

Snow impressions can provide extremely valuable evidence in helping resolve criminal investigations; however, photographing and obtaining a cast of a snow impression is often a challenge for the crime scene examiner. In their presentation, Lesley Hammer and James Wolfe will review and discuss techniques for photographing and casting snow impressions found at the crime scene.

Both the type of snow and weather conditions can be imperative in determining which casting technique to use. Therefore, Hammer and Wolfe will examine methods for utilizing dental stone, fast setting plaster, and sulfur cement casting of snow impressions in order to demonstrate when and where each method is most effective.

Digitally Autopsy as an Option

Matt Chandran, a Malaysian entrepreneur, wants to replace the traditional way of performing an autopsy with digital scanning. This could quicken the process and deal with problems such as “religious sensibilities”. Chandran talks about the huge number of autopsies performed each year. Out of 70 million deaths each year around a tenth of those require an autopsy. Because of this number he sees this digital approach as a service. Chandran wants to remove the distaste of autopsies by using 3D imaging software that won’t require a scalpel. These digital autopsies can make it easier to identify fractures or foreign objects like bullets. Not requiring a traditionally invasive autopsy could be a big advantage. Chandran would like to commercialize this service and have it available to families who would like another option besides the traditional autopsy. Though there are skeptics who think that this digital autopsy won’t be able to replace the traditional way it is certainly a step towards the future.

The real problem for the United States Justice System is that the defense will always question whether not conducting a physical examination could miss valuable information not recorded with a virtual scan.

New Technique for Analyzing Lipstick Evidence

For forensic investigators the issue of contamination is continually present. One concern is trying to analyze lipstick on objects such as glasses, tissues, or cigarette butts without compromising the evidence. A study done by forensic scientists at the University of Kent found a way to identify lipstick without having to even touch it. The technique they use is called Raman spectroscopy. This technique gives the lipstick a “characteristic vibrational fingerprint“ that can be compared to other assorted lipsticks. This development could also give way to other cosmetic evidence.

A New Software for Skull Identification

In the world of criminal investigation there are several forensic databases for trying to identify a person based on information such as fingerprints or DNA. But Ann Ross at North Carolina State University sees a future in similar software for skulls. Ross and her colleagues have created a software that compares digital scans of unidentified skulls to a database of other skulls. This software could help identify characteristics such as race or ethnicity. Ross speaks of how this could help with undocumented individuals or victims of natural disasters. The best part is Ross is providing this service for free. The only problem Ross and her colleagues are faced with is getting their hands on as many skulls as they can to further their database.

Preserving Crime Scene Integrity

When it comes to investigations, one of the most crucial and important elements of the entire process is that of crime scene integrity.  Another words,  has the crime scene or the evidence at the scene been compromised? Because of this, it is absolutely imperative for those examining the crime scene to take all necessary and even unnecessary steps to ensure that the crime scene remains as undisturbed and true to the crime as possible. This article presents various ways that this may be achieved.

Advances in Facial Recognition Software

Facial recognition software is not a new concept, nor is it new technology. However, like many technologies, in its early stages its uses were limited because of the working capabilities of the technology. SRI (Stanford Research Institution) International has introduced what they call the IOM Passport SL System, a new, more effective way to scan multiple targets in a short period of time.
