Forensic Science Exhibit to Teach “Real-World Forensics”

Posted by: on Sep 26, 2013 | No Comments

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 13th.   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.

UK Lets the Cat (DNA) Out of the Bag

Posted by: on Sep 19, 2013 | No Comments

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

Posted by: on Sep 19, 2013 | No Comments

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

Posted by: on Sep 19, 2013 | No Comments

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

Posted by: on Sep 19, 2013 | No Comments

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

Posted by: on Sep 12, 2013 | No Comments

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

Posted by: on Sep 12, 2013 | No Comments

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

Posted by: on Sep 12, 2013 | No Comments

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.

Better Science Could Mean a New Day in Court

Posted by: on Sep 12, 2013 | No Comments

Recently, Texas lawmakers approved Senate Bill 344 which, according to this article, is the first law in America to allow defendants a new trial in light of relevant scientific evidence that was not accessible at the time of the first trial because the science had yet to be developed. For Robert Avila, the passage of this law might save his life. In his original trial, where he stood accused of killing his girlfriend’s 19 month old child in a fit of jealousy while babysitting her two children, Avila denied involvement in the child’s death despite the evidence stacked against him – including a signed confession and evidence that demonstrated that the four-year-old present could not have inflicted injuries serious enough to kill the baby. However, 12 years later, new biomechanical evidence reveals that there is a chance that the toddler could have accidentally caused the child fatal injuries. At the time Avila went to trial, forensic pathologists did not have the tools to consider this possibility. With the passage of this bill, Avila might have another day in court, and another chance to prove his innocence.

Bone Tissue for Toxicology

Posted by: on Sep 11, 2013 | No Comments

There are many different methods used to determine what types of drugs are in a dead body. One new technique that is in the works is examining bone tissue to find what is present.  Since the adult body has 206 bones in it, it is likely that “bones could potentially represent a significant ‘sink’ for drugs and their metabolites.”  This article identifies  two questions, “Is there variation in drug concentration within the same skeleton?” and “Does burial affect drug detection in skeletal tissues?”  These questions are followed by research in an attempt to find answers each question.  All in all, it is found that this technique is still in its infancy, and needs more time and experimenting in order to perfect it.

Computer Software Advances Facial Composite Use as an Investigative Tool

Posted by: on Sep 11, 2013 | No Comments

More and more law enforcement agencies are adopting the use of facial composite software programs as a replacement for facial composite sketches drawn by artists.  The reason for this implementation? Agencies do not possess the funding to employ a full-time sketch artist, nor can they afford to risk credibility by contracting a civilian sketch artist.  In order to combat these problems, agencies are researching and discovering that a computer software designed to create facial composite sketches is more cost-effective and, arguably, more multifaceted than traditional hand-drawn facial composites.  Tech geniuses already exist within criminal justice departments, so training them in the use of another type of software is no daunting task.  “Converting from pencils to pixels is easy.”  Although this appears to be the best route for law enforcement agencies looking to retain the use of facial composites, there are a few considerations to keep in mind:  the quality of the image the computer produces, the time that it takes to thoroughly interview the eyewitness, training to keep up-to-date with the program, and the cost of the software itself.
