DNA testing sophisticated enough to exonerate Anthony Wright was not available in 1993, when a jury found him guilty of rape and murder, but it is now. And so for nine years his attorneys have pushed to see if advances in technology would support his case.
Wake County sheriff's deputies knew little about the man, except that he wore a foreign brand of...
Police in Thailand said Wednesday that DNA...
Columbus, Ohio, will upgrade technology to fix problems with how the Police Division’s crime lab...
All four sessions of NIJ’s Forensic Technology Center of Excellence ‘Familial DNA Searching’ panel series are now available online anytime. Watch the series to learn more about the technical protocols and software, legal challenges, and current policies for familial DNA searching.
Progress is reported on a backlog of rape kits in Detroit and Wayne County, Michigan. County Prosecutor Kym Worthy says the public can think because of television crime programs that DNA matching is effortless. “There’s a lot more work that has to be done,” she said, including finding and interviewing witnesses. “It’s a huge part of the case,” but not all.
The rape suspect, court papers said, was identified by a longtime friend who said they committed the crime together. The suspect’s DNA was tied to the crime. But prosecutors hoping to present an airtight case had a concern: The suspect, Dwayne McNair, has an identical twin, meaning the DNA testing pointed not to one person, but two.
Researchers at Johns Hopkins have identified a highly sensitive means of analyzing very tiny amounts of DNA. The discovery, they say, could increase the ability of forensic scientists to match genetic material in some criminal investigations.
A single fingerprint, lifted with a pipe cleaner and super glue, has led investigators to reopen a 30-year-old murder case.
IntegenX Inc. has announced the first state-wide deployment of the RapidHIT System for real-time matching of DNA profiles. They will use the RapidHIT System in conjunction with the SmallPond database software to store and search over 350,000 DNA profiles.
The sooner every municipality and jurisdiction takes ownership of its own backlog issue and dedicates the appropriate amount of resources to get kits tested, the sooner they can stop worrying about whether some very smart lawyers are going to find a way hold them responsible.
A woman who has been in prison for more than 30 years for a Nevada killing was granted a new trial Monday based on recently discovered DNA evidence that her lawyer said ties an Oregon prison inmate to the 1976 slaying of a Reno student and two killings in California.
The Allegheny County, Pennsylvania, crime lab can perform crime scene investigations for thousands less than other labs and complete the analysis faster. It's one of the top labs in the world, according to Paul Speaker, an associate professor of finance at WVU and principal investigator for the study.
Nearly 18 years after 68-year-old Geraldine Montgomery was found dead in the small northwest Michigan town of Kalkaska, the man falsely accused and convicted of her sexual assault and murder will walk free.
A self-confessed “armchair detective” claims to have solved perhaps the most notorious whodunit ever by claiming to have discovered the identity of Jack the Ripper. Russell Edwards claims Aaron Kosminski, a 23 year-old Polish immigrant who ended up dying in an asylum, was “definitely, categorically and absolutely” the man behind the grisly killing spree in 1888 in London’s East End.
The forensic community is discussing genotype probability modeling as a way to interpret DNA mixtures. The Kern Regional Crime Laboratory (KRCL) was an early adopter of probabilistic genotyping for mixture interpretation. KRCL's adoption of these computer methods enables Kern County to use complex mixture evidence in routine casework, and easily report their match results.
The case of two North Carolina men cleared of 30-year-old murder charges provides one of the most dramatic examples yet of the potential harm from false, coerced confessions and of the power of DNA tests to exonerate the innocent.
Two North Carolina men who have been behind bars for 30 years, one of them on death row, will go before a judge on Tuesday morning to present new DNA evidence of their innocence of the murder and rape for which they were convicted as teenagers in 1984.
Chicago Police Commander Glenn Evans allegedly shoved the barrel of his gun down the throat of Rickey J. Williams in Jan 2013, an act corroborated via DNA testing. So why did it take until Wednesday to charge Evans with aggravated battery and misconduct? According to Cook County State’s Attorney Anita Alvarez, it was because of a backlog of cases awaiting DNA testing at the Illinois State Police crime lab.
A retired Lucas County sheriff’s detective said she kept a DNA sample from murder suspect Andrew Gustafson in her middle desk drawer for more than three years before turning it over to the Lucas County cold case unit in 2010.
A revolutionary handheld and battery-powered DNA diagnostic device invented at the University of Otago is poised to become a commonly used field tool for rapidly detecting suspected viruses or bacteria in samples while also determining the level of infection. It also has many other potential uses, such as border security, forensics, or environmental monitoring.
When Priscilla Berry vanished from her home in 1978 a question-mark was left over the fate of the 39-year-old. But 36 years later police are hoping to solve the mystery of the missing nurse from Mochdre, Conwy county, thanks to new DNA techniques.
Experts working to identify the victims of Malaysia Airlines Flight 17 have gathered DNA samples from 283 people and have positively identified 173. Wim Heijnen of the Netherlands Forensic Institute said the DNA samples do not all correspond to a victim's identification.
A recent study by the British Geological Survey, in association with researchers at the University of Leicester, has delved into the bone and tooth chemistry of King Richard III and uncovered fascinating new details about the life and diet of Britain’s last Plantagenet king. The study indicates a change in diet and location in his early childhood, and in later life, a diet filled with expensive, high status food and drink.
Amid ongoing efforts to address a backlog of unanalyzed rape kits that go untested throughout the country, California lawmakers has passed a bill requiring law enforcement to process the evidence within a certain time frame.
A visit to the Crime Lab can illustrate the advances that the San Bernardino County Sheriff’s Department in California has made over the past several years. The Sheriff's Scientific Investigations Division has handled thousands of cases, and as technology has advanced, so has the crime lab.
In May, police in Falls Township, Bucks County, pulled over Corey Sean Mcgrogan after getting a call about an intoxicated driver. Three months later, he's still waiting for a district judge to review his case and decide if it should go to trial. The delay is the result of a backlog at Bucks County's crime lab for tests that identify illegal substances.
In this report, the authors describe a novel single-cell STR typing method with high sensitivity, fidelity, and throughput that combines microfluidic droplet generation with a single-cell, multiplex emulsion polymerase chain reaction (PCR).
Although DNA analysis of an evidentiary swab may reveal the presence of a DNA profile consistent with an alleged victim, the DNA profile cannot indicate whether the DNA came from saliva, vaginal fluid, urine, or a host of other sources. The ability to confidently associate a DNA extract with a specific tissue source or to accurately characterize mixed stains, however, can provide criminal investigators with critical information.
