Grandaddy Purple, Blueberry Yum Yum and other pot products may now be legal for medical use in 20 states and the District of Columbia, but how do patients know what dose they’re really getting and whether it’s safe? Small labs are setting up shop — some at their own legal peril — to help patients find out.
According to the Missouri Department of Conservation (MDC), DNA testing will help determine if a...
Forensic experts have long used the shape of a person’s skull to make positive identifications...
Between November 2011 and March 2012, four improvised explosive devices were found in southern...
The Kentucky Department of Corrections has issued an action plan to ensure full compliance with state law requiring DNA samples to be collected from all persons convicted of felonies.
The image of six people with somewhat similar features standing side by side as an eyewitness or crime victim peers at them from behind one-way glass has taken on iconic status, becoming a staple of police dramas on TV and in movies. But after discovering that most other big-city departments use lineups far less frequently, Chicago police last month began a pilot program on the South Side to reduce their reliance on them.
A Montana woman on trial for killing her newlywed husband at Glacier National Park told the FBI "I pushed him and I took off." The statement by 22-year-old Jordan Graham was heard on Wednesday, the third day of her trial. She is charged with first-degree murder and second-degree murder in the July 7 death of Cody Johnson, 25.
This study examined electric field tomography as a potential technology for developing a low-cost, non-invasive body-cavity screening device. To overcome the inherent low resolution of the tomography, researchers developed a multi-frequency method using images acquired over frequencies ranging from one to 20 MHz to build a linear model and decompose the different object types (e.g., muscle, bone, plastic) in the image.
Justice Weir described the situation as unacceptable after being told experts refuse to accept any more police exhibits after reaching their monthly quotas. In a hard-hitting assessment of delays in some criminal cases, he suggested that the Justice Minister David Ford may have to "look closer to home" in efforts to speed up the system.
A new quality assurance tool from Leica Geosystems been recognized by the U.S. National Institute of Standards and Technology (NIST) as leading to improved forensics. Created specifically for use with the Leica ScanStation PS20 3D laser scanner, the new Leica Geosystems NIST traceable twin-target artifact definitively confirms the accuracy of Leica ScanStation laser scans while at the scene of forensic investigations.
The goal of this grant was to develop a volume reduction solid phase extraction microchip capable of accommodating large volumes. The device was applied to degraded and compromised samples, and to the purification of mitochondrial DNA. It also was demonstrated in a multiplexed format for as few as two samples.
A decade after her charred body was found in Mississippi woods, authorities have confirmed that a once nameless murder victim is the long-lost sister of a Brandon man. For two years, investigators have run tests to determine if the unidentified woman known as "Rosa Doe" was Asenath Mary Woodin, who lived in Hillsborough County in the 1990's.
Some of it was Roger Holland's blood. Some of it was wife's. Some of it came from neither. And plenty of it, investigators simply can't say. More than 30 stains found in the couple's Apple Valley townhome after Margorie Holland's March 7 death raised many possibilities but offered little concrete about her fate, forensic examiners testified.
Eurofins Scientific, a European leader in Genomics Services, Forensics and Paternity Testing, has announced a milestone in genetic and forensic research. A multidisciplinary Eurofins team in the Eurofins flagship Genomics laboratory in Ebersberg, Germany, has successfully completed a research project to genetically discriminate “identical” monozygotic twins.
A team of researchers from four universities has evaluated the operations of the National Integrated Ballistic Information Network (NIBIN), a program through which firearms examiners at state and local crime laboratories compare tool marks on fired bullets or cartridges found at a crime scene to digitized images of ballistic evidence in a nationwide database.
Clifford Sleigh always had a peculiar habit of wearing baseball cleats. Little did he know, that habit — and his DNA — would some day put him behind bars for a horrific crime that shook the city of Edmonton and area.
Armed with a recent U.S. Supreme Court ruling, a federal appeals court will revisit a controversial legal challenge to California's law allowing collection of DNA samples from anyone arrested for a felony.
Santa Cruz County sheriff's leaders have unveiled a new crime lab and coroner's facility, touting it as a way to streamline criminal investigations. It's the first phase of a three-part, $44 million project that will move the sheriff's headquarters in Santa Cruz, Calif., to three new buildings near by the end of 2014.
The most common and best known use of criminal entomology remains dating the body. The usual forensic methods are no longer efficient after about 72 hours following the death, or when the body shows signs of advanced decomposition. Necrophagous insects and certain arthropods remain effective bioindicators for establishing, more or less accurately, the time of death.
