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.

Agilent Technologies Inc. has introduced the 7200B Quadrupole Time of Flight (Q-TOF) Gas Chromatography Mass Spectrometer (GC/MS) System. The system replaces the company’s GC/QTOF, the 7200A, with new capabilities that will significantly boost laboratory performance.
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.
Four men have teamed up to empower women to prevent sexual assault by giving them a way to detect date-rape drugs. Students from North Carolina State University's Materials Science and Engineering department created "Undercover Colors" nail polish that changes colors when it comes in contact with the date-rape drugs Rohypnol, Xanax and GHB.
The Columbia Police Department in South Carolina has shut down its drug lab after an investigation found an analyst in the lab was not properly trained and her handling and analysis of drugs seized in criminal investigations were likely flawed.
Diagnosis of death by smothering can be very difficult, in many such cases a forensic fiber examination doesn’t take place. In many cases post-mortem examinations fail to establish precisely how the deceased came to die, and likewise toxicological examinations may fail to illuminate any specific cause from a chemical perspective.
The owner of a now-closed Minnesota head shop has been sentenced to 17½ years in prison for selling synthetic drugs in a case that prosecutors said should remove any doubts that substances sold under such names as "incense," ''spice" and "bath salts" are illegal.
Drugs disappearing in dozens of cases are only one piece of a scandal that could shake South Florida law enforcement to its core. Investigations continue into the full breadth of the problems at the Broward Crime Lab.

South Korea's forensic agency said on Friday it was impossible to determine the cause of death of a businessman linked to a ferry that sank killing 304 people in April because there was too much tissue damage to his badly decomposed body.
Controlled substances are chemicals that have a legally recognized potential for abuse. They include “street drugs” such as heroin or ecstasy and prescription drugs such as oxycodone. Detecting and identifying controlled substances is a critical step in law enforcement's fight against drug-related crime and violence.
The Society of Forensic Toxicology Continuing Education and Drug-Facilitated Crimes Committees and the DC Office of the Chief Medical Examiner will co-host a two-day workshop on Drug-Facilitated Sexual Assault (DFSA), taking place online and on location in Washington, DC, on August 11-12, 2014.
Synthetic marijuana — different chemical blends first created in the 2000s to mimic the effects of marijuana — is nothing like its namesake anymore. While original versions had effects on users similar to marijuana, these newer forms of synthetic cannabinoids have wildly different, often much more dangerous effects on users.
A Texas actress who sent ricin-laced letters to President Barack Obama and the New York mayor then tried to blame the crime on her soon-to-be ex-husband was sentenced to 18 years in prison on Wednesday.
Scientific testing has helped investigators in narrow in on the identity of the teenage boy whose skeletal remains were found in 1995. The boy is believed to have died in 1994. The Smithsonian assisted by conducting what’s called stable isotope analysis on a piece of bone fragment from the remains.

With recreational and/or medical marijuana now legal in 21 states and the District of Columbia as of April 21, 2014, according to CNN US, one might wonder if forensic facilities can begin to scale back resources dedicated to the drug’s testing and storage. We believe that this may not be the case.
