Perhaps you are often faced with compromised samples and questions such as: was the DNA concentration too low? Was the DNA degraded or the amplification inhibited? The new Investigator 24plex Kit family contains a unique Quality Sensor (QS) that generates valuable information for quality control and performance checks, which can be used to choose the most appropriate rework strategy.
The Virginia Department of Forensic Science has four laboratories and a plethora of staff and equipment to analyze minute properties in evidence, from strands of DNA to the chemical makeup of methamphetamine. The challenge, though, is finding the time to examine the ever-growing mountain of evidence that comes in every year.
The webinar will introduce the PowerPlex® Fusion 6C System, a 6-color STR system that simultaneously amplifies 23 autosomal loci, three Y-STR loci, and Amelogenin. The twenty required and three recommended expanded CODIS core loci are combined with Penta D, Penta E, DYS570, and DYS576 to give this system a discriminatory power that is unmatched by any other commercially available STR system.
In the past 20 years, forensic DNA analysis has become an indispensable tool in the criminal justice system. Yet despite improvements in chemistry sensitivity and process automation, data generation has remained relatively unchanged. Currently, routine analysis is restricted to the length of STR alleles and only 10’s of markers can be combined in a single system. Comprehensive sample interrogation requires intensive workflows/methods and multiple parallel analyses.
An Ohio judge ruled that TrueAllele® Casework is reliable under the Daubert admissibility standard. Judge Maureen Clancy also denied discovery of TrueAllele source code. The defendant Maurice Shaw accepted a guilty plea shortly after the Cleveland ruling.
The Forensic Technology Center of Excellence will be hosting a two-day online seminar on The Science, Law and Politics of Cold Case Investigations on October 30-31 in order to answer critical questions about cold cases and what it takes to resolve them.
Prosecutors have finished presenting evidence against Munawar Toha, wrapping up their case against the 67-year-old on Tuesday afternoon. A prosecution witness said a key piece of DNA evidence failed to incriminate Toha as the man who dumped his wife’s body in a lake.
Law officers are asking the Oklahoma State Bureau of Investigation how to best collect genetic material from people convicted of certain misdemeanors and enter the information into a national database.
A Nevada law that requires DNA samples be taken from every person arrested on a felony charge — and criticized by civil rights groups as an invasion of privacy — has seen surprisingly little pushback in the four months it has been in practice.
Human remains recently exhumed from an Alabama grave are not those of the notorious fugitive William Bradford Bishop, who is accused of killing five family members with a small sledgehammer in Montgomery County in 1976 and setting their bodies on fire, law enforcement officials say.
A California state audit report has found that nearly half of all sexual assault evidence kits at three selected law enforcement agencies were never analyzed — and that many lacked a clear explanation why.
It was news that gave parents hope: None of the bodies found in five mass graves in southern Mexico belonged to 43 teachers college students who have been missing for nearly three weeks since a clash with police.
Hearings began Tuesday in the killings of two British tourists on a Thai resort island, a case plagued by missteps by the Thai police that could further damage a tourism industry that is already suffering a downturn after the May military takeover.
Before DNA, most forensic evidence was serology or matching blood types. Finger print recognition was also one of the most common and reliable methods for catching criminals, and it’s still the most widely used method of identifying suspects. But DNA is a game-changing tool that provides investigators with infallible evidence upon which they can build a case.
Turns out all those detached feet in sneakers that have washed up on British Columbia shores since 2007 aren’t such a mystery after all — except for two feet belonging to the same unknown man.
An investigation shows the state of Oklahoma relied on faulty blood analysis, the dubious testimony of a troubled 14-year-old neighbor and an unrecorded, incriminating statement to convict Michelle Murphy.
The Wyoming Game and Fish Department has finished an analysis of DNA collected at the scene of the fatal bear encounter northwest of Dubois. The Game and Fish also completed an extensive investigation at the scene of the incident and surrounding vicinity and has worked closely with the Fremont County Coroner, Sheriff and Search and Rescue.
A DNA expert testified that one particular blood drop found on 22-year-old Dajeon Franklin's shoe matches slain University of Michigan medical student Paul DeWolf when the murder trial continued.
DNA is relatively new — barely into its 30s. But as a science, it has advanced rapidly. Last month, authorities touted how "touch" DNA technology helped to swiftly identify a suspected serial rapist, James W. Daniel III, based on a few skin cells left behind in the jeans pocket of a woman who reported an attack.
Battelle has been awarded a federal grant in excess of $800,000 from the National Institute of Justice to conduct feasibility and validation tests on a suite of new investigative tools that use next-generation sequencing (NGS) to unlock new clues from DNA evidence.
A $4.4 million effort to test rape kits dating back to 1987 by the city of Houston has produced more than 1,000 DNA databank matches and charges against 19 people.
A forensic scientist working for the Washington State Patrol swabbed a steering wheel from a slain woman’s car. Detectives had wrapped it up and tucked it away as evidence in 1995, within days of the stabbing death.
DNA expert witnesses dueled recently in the New York murder trial of Timothy Matthew Jacoby, accused of shooting and killing 55-year-old Monica Schmeyer during a 2010 burglary. Prosecutors are seeking the death penalty for the murder, so the testimony of DNA experts will prove crucial to the defendant’s fate.
It’s no bigger than a microwave oven from the 1980s, but a machine inside the Oxford Police Department can test DNA in less than two hours. The department is putting the NetBio rapid DNA analysis system through a series of tests. If it works as intended, the department may buy the approximately $250,000 system.
Thousands of rape kits remain untested in four major U.S. cities, according to new data on rape kit backlogs released recently by the Joyful Heart Foundation.
