Determination of Blood Alcohol Content has been a standard analytical method in criminal labs for many years. Recently, however, additional compound identification provided by matching the ethanol mass spectrum to a library spectrum, in addition to RT, has proven to offer an additional level of confirmation. This article describes BAC analysis using a GC-FID in parallel with a mass spectrometer for positive compound identification.

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.
A compact Raman workstation for forensic applications, the Foster + Freeman Foram3 provides examiners with the full analytical power of 785nm Raman spectroscopy in an easy-to-use PC operated system.
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.
NIJ’s Forensic Technology Center of Excellence is hosting a Technology Transition Workshop, “Crime Scene Solutions: Utility of 3D Scanning Technologies in the Investigation Process,” on October 28-29. The workshop will enhance forensic science practitioner’s knowledge of 3D crime scene scanning technologies, including strengths, limitations and implementation strategies.
Coalition-supported lab analyzes ballistics, fingerprints and other evidence.
A disputed bite-mark identification is at the center of an appeal that was filed with the Mississippi Supreme Court. Eddie Lee Howard Jr., 61, has been on death row for two decades for the murder and rape of an 84-year-old woman, convicted largely because of what many experts call a far-fetched match of his teeth to purported bite wounds, discerned only after the woman’s body had been buried and exhumed.
The AriaMx System is the first instrument for real-time polymerase chain-reaction (PCR) that features easily-changeable optics cartridges for genotyping via high-resolution melt, gene-expression analysis, pathogen detection, and a variety of complex research applications.
Typically, managers dread having to perform employee assessments and experience high anxiety anticipating them. For the employee, too, who is about to undergo a formal performance assessment, the procedure is a high-anxiety producer. So what typically happens is that two very nervous people get together, try to act calm, and just “get through it.”
Firefighters from two houses in SoHo rushed to Henry Street in Chinatown one June morning two years ago. Smoke filled a ground-floor apartment. Two women were inside, motionless. Both women had been fatally shot, their exit wounds not immediately visible to their would-be rescuers. It is a rare, if age-old, turn of events in the city: A person found dead after a fire turns out to have been the victim of a homicide.
The WVSP Forensic Lab, an accredited, full-service laboratory, serves all 55 counties in West Virginia, including all law enforcement agencies from the local to the federal level. The lab has the potential to service over 800 agencies from all across the state.
The Bureau of Criminal Investigation facility currently under construction on the Bowling Green State University campus will also be the home of the Ohio Attorney General’s Center for the Future of Forensic Science. On September 11, BGSU President Mary Ellen Mazey and Ohio Attorney General Mike DeWine announced that Dr. Jon E. Sprague will serve as the first director of the center.
A cataloguing method for comparing the land impressions of bullets, using readily available commercial instrumentation and software, is described.
Move over, graphene. An atomically thin, two-dimensional, ultrasensitive semiconductor material for biosensing developed by researchers at UC Santa Barbara promises to push the boundaries of biosensing technology in many fields, from health care to environmental protection to forensic industries.
A South African judge on Friday found Oscar Pistorius guilty of culpable homicide in the shooting death of girlfriend Reeva Steenkamp but declared him not guilty of murder. Prosecutors said they were disappointed by the ruling but would decide on whether to appeal only after sentencing.
Agilent Technologies Inc. will introduce its latest innovation in ultra-high-performance liquid chromatography (UHPLC) on September 23 at Analytica China, the international trade fair for laboratory technology, analysis, biotechnology and diagnostics held in Shanghai.
