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 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.
A chewed lollipop stick, left behind at the scene of a March burglary, has been traced back to a North Naples, Florida man who has been arrested at his home.
Human mitochondrial DNA (mtDNA) analysis, in a forensic setting, is currently limited in breadth (the quantity of sequence data obtained) and depth (the ability to detect minor variants arising from mutations but present at very low levels). The goal of this research was to generate information on the whole mtDNA genome sequence from limited DNA samples, which would greatly expand the potential uses of this marker system.
Dutch officials expect precise accuracy from DNA-matching software that will be used to identify many of the 298 Malaysia Airlines flight MH17 victims. But it is unknown whether there will be enough genetic evidence from the remains and relatives of the missing to ID everyone.
DNA evidence taken from the clothing and body of Carol Alford a quarter-century after her death linked her slaying to a serial killing suspect with such certainty that no other person on Earth could have deposited the cells, an expert has testified.
In a dusty, seemingly empty field 60 miles east of L.A., Dr. Alexis Gray, a forensic anthropologist from the San Bernardino County Sheriff Department, points to a chain-link fence far in the distance, the mountains rising beyond in the hazy heat. "There are 7,000 people between us and that next fence there," she says. For almost a decade, her job has been to confirm the identification of every single one of them.
The primary research objective was to develop a single nucleotide polymorphism (SNP) panel to identify animal species from forensic samples of unknown biological origin by using mitochondrial DNA (mtDNA)-based markers.
On Thursday, August 21, NIJ’s Forensic Technology Center of Excellence is hosting the final session of a four-part online discussion about familial DNA searching.
Over the past 20 years DNA evidence has become the foundation upon which forensic investigation is built. But as new identification technologies emerge at an ever quickening pace, new questions are being raised as to not only the efficacy of these technologies, but also their implications on privacy, civil liberties and validity.
Addressing the issues surrounding the testing of sexual assault kits (SAKs) is one of the most complex challenges facing our nation’s criminal justice system. To help find the best strategies, methods and procedures for dealing with SAKs, the FBI and NIJ have formed a research partnership. The long-range goal is improved practices and policies for law enforcement and crime labs.
DNA evidence can be critical to solve a crime, but a big backlog of cases means it could be months, or even years, before some of those samples get tested.
About $41 million has been earmarked to help expedite the nationwide processing of rape kits. Pending final budgetary approval, the funds would help local police agencies and crime labs address a severe backlog in the analysis of some 500,000 rape kits across the country.
The parents of a six-year-old Washington girl found slain last week sat in a courtroom as a judge ordered a 17-year-old boy under investigation in the child's death and sexual assault held on $1 million bail. Authorities said they linked evidence found near the girl's body to the DNA of Gabriel Gaeta, who was friends with her family.
A motion for DNA testing filed by convicted killer Larry Ray Swearingen was granted Monday by 9th state District Court Judge Kelly Case. Swearingen is on death row awaiting an execution date, but Case granted the inmate’s request for testing of seven categories of evidence to determine whether any DNA was left on items at the time of the 1998 capital murder of Montgomery College student Melissa Trotter.
Richland County Sheriff Leon Lott says a new DNA technology tool helped his department make an arrest in an attempted murder case. Lott spoke Wednesday about the investigation, which he says was solved in part with the agency's recently acquired rapid DNA system.
Recently, Corning Incorporated, together with Polytechnique Montreal, is developing a type of smart glass mainly used as the touchscreen of the smartphone, which can detect people's physical condition and can even analyze the user's DNA through reading the spit on the surface of the smart glass. Besides, this smart glass can also detect the composition of the atmosphere.
A Long Island man who spent nearly 18 years in prison before his conviction for killing his wife in 1994 was overturned by new DNA evidence has filed state and federal lawsuits against the Vermont police and prosecutors who built the case.
Two decades later, forensic work by the Suffolk County Police Department, along with changes to DNA collection procedures, have brought some long-delayed relief to family and friends: John Bittrolff, 48, a carpenter and married father of two from nearby Manorville, was arrested last month on charges of murdering Ms. McNamee and Ms. Tangredi.
There may be a shortcut in rape investigations that would capture valuable DNA evidence while cutting costs and getting Utah law enforcement agencies out of the bind of backlogged forensic evidence in rape cases. It looks to be one of the most significant developments to come out of "passionate" discussions between members of an ad hoc group seeking solutions to unanalyzed rape kits.
Fifteen months is a long time to wait for a hearing date on whether forensic testing should be conducted on evidence, say lawyers for a Bloomington man serving life in prison for a murder he claims he did not commit. Advocates for Jamie Snow say they are hopeful the appointment of a new judge in the Eighth Judicial Circuit will mean progress in Snow's efforts to argue his innocence.
