Picking Up the Dead Ends

In Utah, the murder of Krystal Beslanowich appeared to have gone cold. That is, until the police utilized a vacuum, known as the M-Vac, that picked DNA off the murder weapon and obtained the full DNA profile that the police had been missing. The vacuum proved effective because it can gather more DNA than a traditional cotton swab from any surface area, including polyester, nylon, or in this case, a rock. However, forensic analysts note that while the tool was helpful in this case, a forensic vacuum is often used as the last resort for evidence collection because the vacuum will collect everything that ever touched the object being investigated.

Sink Your Teeth into this Debate over Forensic Dentistry

Forensic odontology has arisen as a potent controversy among criminal justice professionals on whether or not the practice should even continue. The Innocence Project, a group that aims to exonerate wrongfully convicted people with the use of DNA evidence, claims that forensic odontology is a “junk science,” and advocate for the abandonment of the practice. Along with the Innocence Project, the National Academy of Sciences (NAS) questions the validity of this forensic technique. In a paper published by NAS four years ago, they concluded that there is a “lack of valid evidence to support many of the assumptions made by forensic dentists during bite mark comparisons.” On the other side of the debate, Dr. Gregory Golden argued that bite mark evidence has led to multiple solid convictions, including that of serial killer Ted Bundy. He goes on to say that bite marks can also be useful in identifying age, victims of mass casualties, and to spot child abuse. Although limited scientific studies exist to support the claims of forensic dentists, Golden persists that forensic odontologists offer an accurate analysis up to 98% of the time.

Microscopic Criminal Catchers

A research facility in southeastern Texas has been investigating the use of bacteria as a new forensics tool. Entomologist, Sibyl Bucheli, was inspired by her work with insects, and thought, “If insects change through time, then so do bacteria…And if insects can be used, so can the bacteria.” The researchers at the facility believe microbes could offer endless possibilities in enabling police investigations. Among these possibilities include improving time-of-death estimates, determining cause of death, linking individuals to things they have touched, and concluding if a body was moved after death. Although the research remains in the early stages of development, with practical uses for the research years away, the scientists eagerly take on this challenge of microscopic investigative analysis.

Forensic Science Exhibit to Teach “Real-World Forensics”

Recently, a traveling forensic science exhibit debuted at the Sciencenter in New York. The “Crime Lab Detective Unit” exhibit was developed at The Museum of Discovery in Arkansas and was then transported to New York for the unveiling on September 13^th.   A spokesperson for the Sciencenter explains that the exhibit is designed to demonstrate what “real-world forensics” is like to the public in order to diminish that CSI effect.  Participants are given the option of a short or long version of the burglary investigation that they are being enlisted to help solve. Then, they are taken through a series of workshops that include interviews, fingerprinting, lab testing, and much more.  Ultimately, the “investigators” will offer their determination of the guilty party before finding out if they successfully solved the case.

For more information on this exhibit, please check out the article here

UK Lets the Cat (DNA) Out of the Bag

In this case, it’s not as important to consider what the cat “dragged in”, but rather what the cat left behind. Besides being a furry household feline friend, cats are now proving very useful in forensic investigations.  During a recent death scene investigation in the UK, law enforcement officials were able to use cat hair DNA to convict David Hilder on manslaughter. Among the evidence that convinced the jury of Hilder’s guilt was a cat hair found on the body.  The hair, after being compared with 152 other local UK cats, proved to be a positive match to Hilder’s cat, Tinker. The UK has just begun to realize the forensic benefits of animal DNA. The US has been reaping these benefits for years largely through a database located in California. So, next time you’re thinking your four-legged friend is a nuisance, remember how important he could be.

A Look at Psychopathy

A Look at Psychopathy

Today, it is a generally accepted claim that psychopaths have had some sort of horrifying experience in their past that has led them to become the way that they are. However, people rarely consider any evidence to support these assumptions. A recent study at a Mexican prison investigated these suppositions. With psychologists’ help, scientists were able to interview inmates, rank their level of psychopathy, and then explore traumatic events of their past. The study outlines all of the details including methods, measurements, statistics, and techniques. At the conclusion of the study, the findings showed a relationship between inmates possessing a higher level of psychopathy and significant childhood victimization and exposure to physical and sexual abuse. The results of the study go on to explain how these traumatic events would eventually shape the characteristics of psychopaths. This study not only supports the aforementioned assumptions, but also lays out the scientific support for them – a worthy read!

A Little Help on Dealing with Unusual Surfaces

Lifting prints or receiving evidence from a surface other than what we would expect to be normal is quite hard. Dick Warrington, in his article “tools of the Trade: Dealing with Unusual Surfaces,” goes into how to lift prints and other evidence from surfaces that do not fit the everyday category. The surfaces he covers are multi-textured/multi-contoured, adhesive surfaces, dust surfaces, and wet surfaces. When speaking about multi-textured surfaces, Warrington gives three examples of products and techniques that can be used to help find evidence. The three of those products are AccuTrans, polyethylene tape, and DIFF-Lift tape. Each of these help the user to lift fingerprints and other pieces of evidence from surfaces that are definitely harder to get evidence from.

Improved Microfluidic Technique for DNA

Forensic DNA testing has become a valuable technique for professionals in the criminal justice field due to its ability to accurately and consistently link DNA evidence to an individual or another source. However, accuracy comes into question when the DNA sample comes from contaminated or crude evidence. Researchers at the National Institute of Standards and Technology and Applied Research Associates, Inc. have created an improved microfluidic technique designed to overcome extracting a full DNA signature from “real-world, complex mixtures such as dirt.” This new technique will save time and make DNA much easier to obtain from these otherwise difficult samples.

Using Insects to Determine Time of Death

Body temperature, lividity, rigor mortis, decomposition – all factors in estimating time of death. What’s a surprising element that can also aid in TOD estimation? BUGS. That’s right. Contrary to being an unwelcome visitor in your home, insects discovered at death scene investigations are considered to be important pieces of evidence. By examining these bugs, investigators can discover whether or not a body was moved, if a body has been disturbed, if drugs were present in the body prior to decomp, notably, the time of death, and much more. Researcher and crime scene consultant, Dick Warrington, stresses that in order for crime scene investigators to take full advantage of the benefits provided by forensic entomology, they must first understand how to handle the scene. Observing, recording, photographing, and collecting samples of the insects is the key for an accurate analysis. If all steps are completed properly, forensic entomologists can uncover the aforementioned invaluable information.

Government Crackdown on Polygraph Instructors

In order to send a “strong message” to individuals teaching methods on how to pass polygraph examinations, U.S. District Judge Liam O’Grady sentenced Chad Dixon, a little league coach and polygraph instructor, to eight months in prison for teaching up to a hundred people, including sex offenders and government employees, how to defeat lie-detector tests. This case and its decision led to questions regarding the government’s campaign against instructors like Dixon. Among the debates were whether or not the government should continue its hunt for these offenders, and where the line was drawn between an individual’s first amendment rights to discuss how to approach the polygraph exam and the “crime of teaching someone to lie while undergoing a government polygraph.”

Processing of Abnormal Surfaces Made Easier

Some people hold the belief that irregular surfaces cannot be processed in a way that yields useful results. Well, Dick Warrington, researcher and crime scene consultant, is here to challenge that belief. Dick explains that all surfaces can be processed as long as the appropriate method is used. He goes so far as to say, “…the only ‘surfaces’ where you can’t get prints are air and water…”. Right away, he launches in to offer some possible processing techniques for the most difficult surface – multi-textured/multi-contoured surfaces. A tool resembling a caulking gun called AccuTrans can be used on this type of surface to create casts of impressions and lift prints. This tool produces better results than other methods because it mixes its chemicals for you. Another instrument that can be used to process multi-contoured surfaces is polyethylene tape to lift prints. This works well because it can conform to the shape of the surface hosting the print. Another device that can be used on this type of surface that is worth mention is DIFF-Lift tape. Because it is so much stronger than traditional lifting tape, DFF-Lift tape can lift a print from very textured surfaces. Besides multi-textured/multi-contoured surfaces, there are also adhesive, dust and wet surfaces that seem difficult to process. An adhesive side powder can be used to lift prints from an adhesive surface. Electrostatic dust lifters such as PathFinder allow prints to be lifted from dusty surfaces. Finally, a small particles reagent can be used on wet surfaces to retrieve prints. Provided with just these examples, it is evident that surfaces of all types can be processed successfully – as long as the correct technology is utilized.
