2018-01-26 | Developing a Roadside Test for Marijuana Intoxication Isn't as Easy as It Sounds
As the movement to legalize marijuana in the United States gains momentum, researchers worry about keeping the public safe, particularly on the roads. Recent studies in which marijuana users took controlled doses of cannabis in the lab have identified new biomarkers that can be used to estimate a person's recent cannabinoid intake. But, using those markers to judge cognitive and behavioral impairment is complex, say toxicologists in a commentary published on January 25 in a special issue of the journal Trends in Molecular Medicine on biomarkers of substance abuse.

2018-01-26 | DA review identified 254 cases that could be re-examined because of DNA issue
The letters are not an acknowledgment that the convictions are invalid, or that prosecutors even suspect there are problems with them, and don’t precisely spell out how a case will be handled. Stephan wrote that in “appropriate circumstances” some of the DNA matching conclusions could be re-calculated, or some evidence — if it still exists — may be retested.

2018-01-10 | Convicted Triple Murderer Alleges Bogus Snow Imprint Forensic Analysis in Federal Suit
Those two pieces of forensic analysis were provided by the first named defendant in the new lawsuit, G. Michele Yezzo, a former forensic scientist at the Ohio Bureau of Criminal Investigation—whose work on multiple criminal cases has been questioned. Five years before the triple murder, an internal BCI memo had stated Yezzo’s “findings and conclusions regarding evidence may be suspect. She will stretch the truth to satisfy a department.”

2017-12-01 | New Findings: Burglars Have One of Four Personalities—and They’re Finally Getting Caught
“I think an even more important, but very unexpected, finding was what happened to the number of burglaries occurring in the treatment departments’ jurisdictions after they started implementing the burglary profiles,” said Fox. “Specifically, results show that they had 40.9 percent fewer burglaries occurring in their jurisdictions, likely because they were doing a better job of putting so many more bad guys away!”

2017-11-29 | Forensic Technology Developed in UK Will Make It “Impossible” for Criminals to Destroy Fingerprint Evidence
New forensic technology created by scientists at Loughborough University will make it “impossible” for criminals to erase their fingerprints from crime scenes. The advanced detection technique, which allows investigators to take prints from problematic exhibits, such as spent ammunition casings, was carried out in partnership with the Defence Science and Technology Laboratory (DSTL) - an executive agency of the Ministry of Defence. Those involved in the innovation said it will make it far easier for police to recover impressions from previously problematic crime scenes involving materials subjected to high temperatures, or immersed in water or prints left on deformed surfaces.

2017-11-27 | Cat Hair Helps Nab Woman Accused of Mailing Bombs to Obama, Texas Gov.
An obliterated shipping label on the package sent to Abbott led investigators to Poff's address in Sealy, and a cat hair found under the shipping label of the package sent to Obama matched one of Poff's cats, the indictment says.

2017-11-22 | Faulty Forensics: Explained
In our Explainer series, Fair Punishment Project lawyers help unpackage some of the most complicated issues in the criminal justice system. We break down the problems behind the headlines — like bail, civil asset forfeiture, or the Brady doctrine — so that everyone can understand them. Wherever possible, we try to utilize the stories of those affected by the criminal justice system to show how these laws and principles should work, and how they often fail. We will update our Explainers monthly to keep them current.

2017-11-22 | Texas Man Confesses to 18-month-old Homicide Days After Release of DNA Phenotype Profile
It wasn’t until Nov. 15 that Riggs confessed at North Lake Community Church in Brownwood, and then gave police “a full confession” with details that matched up to the evidence of the case, Hill said. The sheriff said the “Snapshot” played a large role in Riggs’ apprehension, and that he had not been on their "radar" prior to the phenotype analysis.

2017-11-22 | Local Pennsylvania Police Use Rapid DNA Hit for First Time, Nabbing Alleged Killer at Hospital
The bloody clothing of a patient admitted to a hospital with a stab wound was linked to a bloody trail at a crime scene, leading to homicide charges within hours. Rapid DNA, a quickly-spreading technology that got a boost with federal legislation this summer, was what allowed the quick resolution of the murder of 35-year-old Rhyhiem Hodge on Nov. 12 in Carlisle Borough, Pennsylvania, according to the Cumberland County District Attorney’s Office.

2017-11-09 | NY Chief Judge Directs Judges to Remind Prosecutors, Defense Attorneys of Their Duties
The new order “provides a mechanism by which to educate inexperienced prosecutors and defense attorneys—and remind experienced ones—about their constitutional and ethical duties,” the Empire State’s court system said in their Wednesday announcement. The Brady material would include all exculpatory material that could be favorable to the defendant, either through attacking the credibility of witnesses, reducing the scope or severity of the crime, or otherwise offsetting the prosecutions’ arguments. The defense attorneys would have to keep the client informed about the case, provide reasonable advice for plea offers, and conduct investigations of case facts and relevant case law, they add.
