Wet vacuum DNA collection used in cold case murder at Torrey Pines

new blue helixSAN DIEGO (CBS 8) – Cold case detectives have the results back from new DNA testing in the 1978 murder of a teenage girl on Torrey Pines beach.
Even though the murder has remained unsolved for 38 years, San Diego police detectives were hoping for a break using wet vacuum DNA collection technology.

Hair Plus DNA May Advance Forensics

HairWEDNESDAY, Sept. 7, 2016 (HealthDay News) — Certain proteins in the hair can be used alongside DNA in forensics and archeology, researchers report.
DNA is unique to each person but can degrade over time. These hair proteins are more stable than DNA, and can help with human identification, the researchers said.

Pollen genetics can help with forensic investigations

pollenImagine you’re a detective working on a murder case. You have a body, but you believe it was moved from another location. Now what? There’s one unexpected tool you might use to follow up on this suspicion: forensic palynology. That’s the application of palynology – the study of pollen – to crime investigation.

New Tools Find DNA Needles in Genetic Haystack

Exact ID SwabElusive criminals are about to meet their match. Advances in forensic DNA profiling soon will give investigators and analysts the ability to pull genetic data once considered disposable. The breakthrough allows law enforcement to generate information such as gender, hair and eye color, ethnicity and geographic origin from the DNA samples of perpetrators who otherwise might evade detection if they were not part of a DNA database. Gone are the days when non-matching DNA samples signified a dead end.

DNA testing by University of Canberra forensics lab to make molecular sketches of crime suspects

McNevinA Canberra forensic laboratory will be the first in Australia to test the ancestry of crime scene DNA, opening up a world of potentially predicting a suspect’s eye or skin colour.

House Committee Ok’s Bill Letting The FBI Use Rapid DNA Profiling

new blue helixA DNA evidence bill that would let police in the field, not just technicians in an accredited lab, quickly test the genetic material of suspects has advanced to the House floor.
The measure centers around a relatively new screening instrument the size of a printer, called Rapid DNA.

NIST 3D Ballistics Research Database Goes Live

3D Impressions NISTIt’s a staple of the TV-crime drama: a ballistics expert tries to match two bullets using a microscope with a split-screen display. One bullet was recovered from the victim’s body and the other was test-fired from a suspect’s gun. If the striations on the bullets line up—cue the sound of a cell door slamming shut—the bad guy is headed to jail.

Laboratory Artist Puts a Human Face on Unidentified Remains

unidentified remainsNationwide, about 4,400 unidentified remains are found each year—and more than 1,000 of those are still unidentified a year later, according to the National Institute of Justice, which maintains searchable databases of missing and unidentified persons ( Medical examiners and local police departments most frequently become the stewards of unidentified remains. And each year, about 20 requests are made to the FBI Laboratory to develop facial approximations of unidentified individuals to help investigators ultimately put a name to a face.

How Science Is Putting a New Face on Crime Solving

National Geo ParabonA roadside memorial marks where Sierra Bouzigard’s body was found seven years ago in Calcasieu Parish, Louisiana. There were no witnesses to the murder, and the DNA under her fingernails matched none of the suspects. Yet Detective Les Blanchard—here revisiting the scene—is hopeful a new forensic technique might help solve this cold case.

Could crime scene bloodstains reveal a person’s age and the time of the crime?

bloodstainsA new forensic method could allow law enforcement to determine whether blood at a crime scene came from a minor or an adult, and when the suspect or victim left it behind (Anal. Chem. 2016, DOI: 10.1021/acs.analchem.6b01169).

Meet Kristina Pearson, Operations Lead on the Spectrum Launch Team

Spectrum ImageryLate in 2016 Promega will introduce the Spectrum CE System for forensic and paternity analysis. Building this system requires of the efforts of many people from many disciplines–from our customers who have told us their needs to the engineers and scientists building the instrument and ensuring its performance. Periodically we will introduce our Promega Connections readers to a team member so that you can have a sneak peak and behind-the-scenes look at Spectrum CE System and the people who are creating it (of course if you truly want to be the first to know, sign up at to receive regular, exclusive updates about Spectrum CE).
Today we introduce Kristina Pearson, Operations Lead.

Multiple leads generated by DNA composite sketch of Fay murder suspect

snapshot1As part of their ongoing investigation, police recently requested a Snapshot Phenotype Report from Parabon Nanolabs Inc. be conducted on a DNA sample believed to be from Fay’s murderer. The test technology is approximately four years old and uses the DNA profile to make an analysis to predict the physical appearance and ancestry of the sample owner. It is commonly used to develop investigative leads, narrowing suspect lists and identifying unknown remains.

M-Vac DNA Collection Highlighted on NBC’s Dateline

M-VacM-Vac Systems wet-vacuum forensic DNA collection system was highlighted on Friday as part of NBC’s Dateline episode “The Girl with the Red Shoe”. The episode, which first aired on May 6th, covered the Annie Kasprzak murder, which occurred March 10, 2012 along the scenic Jordan River in Draper, Utah. The case, which took over two years to fully investigate, finally concluded with Darwin “Chris” Bagshaw pleading guilty on February 29, 2016.
