A crime-fighting ‘magic’ marker pen that can identify the hidden properties of receipts containing fingerprint deposits within a matter of seconds is one of many innovative gadgets developed by scientists at the University of Leicester.
A British man accused of arranging the murder of his wife during their honeymoon in South Africa pleaded not guilty on Monday to all charges. It was the first day of a trial delayed for years by an extradition process between South Africa and the United Kingdom.
DNA expert witnesses dueled recently in the New York murder trial of Timothy Matthew Jacoby, accused of shooting and killing 55-year-old Monica Schmeyer during a 2010 burglary. Prosecutors are seeking the death penalty for the murder, so the testimony of DNA experts will prove crucial to the defendant’s fate.
It’s no bigger than a microwave oven from the 1980s, but a machine inside the Oxford Police Department can test DNA in less than two hours. The department is putting the NetBio rapid DNA analysis system through a series of tests. If it works as intended, the department may buy the approximately $250,000 system.
Thousands of rape kits remain untested in four major U.S. cities, according to new data on rape kit backlogs released recently by the Joyful Heart Foundation.
State officials worked Monday to determine whether 28 bodies found in a clandestine grave are students who were attacked by police suspected of drug gang links in the southern state of Guerrero. State Prosecutor Inaky Blanco said the bodies are badly damaged and that genetic testing could take two weeks to two months to determine if they are some of the 43 college students reported missing after the violent confrontation in Iguala.
Police are waiting for the results of forensic tests to discover if there is evidence showing whether their prime suspect Arnis Zalkalns murdered the teenager Alice Gross. Zalkalns’s body was found on hanging from a tree in dense woodland in Boston Manor Park, west London, bringing to an end a four-week search.
If modern DNA results had been available in the 1993 capital murder case of Richard Bryan Kussmaul, it is “reasonably probable” that he and his three co-defendants would not have been found guilty, a retired state district judge has ruled.
Authorities are taking a fresh look at unsolved rape, murder and missing persons cases after a man was charged in the abduction of a University of Virginia student who vanished about three weeks ago.
A new report from the National Research Council recommends best practices that law enforcement agencies and courts should follow to improve the likelihood that eyewitness identifications used in criminal cases will be accurate.
Currently, the most reliable biological indicator of time since death in decomposition cases is blow fly development. Because insects do not maintain constant body temperatures, development is a function of time and temperature. Consequently, having accurate models for describing temperature and blow fly development is essential in producing accurate estimates of the post mortem interval (PMI).
A new government study found deaths from heroin overdose doubled in just two years in much of the United States. Overdose deaths from powerful painkillers continue to be much more common, but they declined slightly as the heroin deaths increased.
The search for missing University of Virginia student Hannah Graham now includes the use of an aerial drone — the first time, according to authorities, one has been used in the search for a missing person in the state of Virginia.
A group of researchers has thrown light on the precise mechanisms responsible for the impressive ability of nanoparticles to detect fingermarks left at crime scenes. The researchers have provided evidence contesting the commonly accepted theory that nanoparticles are attracted to fingermarks electrostatically.
Leica Geosystems has announced a 12-month initiative to support the National Law Enforcement Officers Memorial Fund (NLEOMF).
