Jeff Sessions and the Odds of Imprisoning Innocents - The Atlantic. The Washington Post reports that Attorney General Jeff Sessions “will end a Justice Department partnership with independent scientists to raise forensic science standards.”
How Science Is Putting a New Face on Crime Solving. This story appears in the July 2016 issue of National Geographic magazine.
On the morning of November 23, 2009, a cyclist riding near Lake Charles, Louisiana, discovered the body of a young woman lying near a country road. Her face had been beaten beyond recognition, but an unusual tattoo led the police to identify her as 19-year-old Sierra Bouzigard. Investigators from the Calcasieu Parish Sheriff’s Office, headed by Sheriff Tony Mancuso, immediately set about reconstructing her final hours. The people who last saw Bouzigard alive had let her use their phone. The number she dialed gave police a lead. Parabon’s DNA Phenotyping Had Crucial Role in North Carolina Double-Murder Arrest, Conviction. A couple were gunned down by an intruder in their North Carolina home in the early hours of Feb. 4, 2012.
The teenaged daughter had seen the hooded gunman, when he had briefly held a knife to her throat, but she could apparently not describe him to cops. The attacker left several drops of blood on a handrail as he fled, apparently self-inflicted from his blade. Fingerprint Analysis: How It’s Done. Refua umishpat 25 143. SANGERO fingerprints. Are These Crime Drama Clues Fact or Fiction? – Phenomena: Gory Details. I’m often just as surprised by what forensic scientists can’t do as by what they can.
In the Netflix documentary Making a Murderer, for instance, the question of whether police planted the main character’s blood at a crime scene comes down to whether or not the FBI can detect a common laboratory chemical called EDTA in a bloodstain. On a TV crime show, this would be a snap. The test would take about five minutes and would involve inserting a swab into a magic detector box that beeps and spits out an analysis of every substance known to humankind. In real life, there’s no common and accepted test in forensic labs for EDTA even today, nine years after the FBI tested blood for the Steven Avery trial featured in Making a Murderer.
Richard III - Family tree/lines of descent - Michael Ibsen - University of Leicester. The University of Leicester’s Department of Genetics is famous as the birthplace of DNA fingerprinting, discovered here by Professor Sir Alec Jeffreys in 1984 and widely used by governments and law enforcement since then.
However, a different approach was required when the Department of Genetics’ Dr Turi King set out to investigate whether Skeleton 1 from the Greyfriars site was the remains of Richard III involving possible connections between individuals born five centuries – and many generations later – than Richard. The vast majority of our DNA is a very complex mixture of DNA passed down to us from our ancestors.
However, two segments of our DNA have a very simple pattern of inheritance: both mitochondrial DNA and the Y-chromosome are copied and passed down virtually unchanged (barring naturally occurring mutations) down through the generations and therefore could be used, after all these years, for the DNA identification purposes. DNA Forensics: Dr. Jeffreys demonstrated that a genetic or DNA fingerprint is specific to each individual.
DNA Fingerprinting In September 1984, Dr.
Alec Jeffreys, a geneticist from the University of Leicester in Great Britain was studying hereditary diseases in families. He was focusing on methods to resolve paternity and immigration disputes by demonstrating the genetic links between individuals. Jeffreys used Restriction Fragment Length Polymorphism (RFLP) to analyze Deoxyribonucleic Acid (DNA).

Paternity Testing with STR Data In this activity, you will assume the role of a Human Geneticist in a DNA Paternity Testing Laboratory.
You have just obtained the DNA Profiles for Bob, Anne, David and Katie. You also have information about Bob's parents, Fred and Norma. Bloodstain pattern analysis. Bloodstain pattern analysis (BPA), one of several specialties in the field of forensic science, inolves the study and analysis of bloodstains at a known or suspected violent crime scene with the goal of to helping investigators draw conclusions about the nature, timing and other details of the crime.
The use of bloodstains as evidence is not new; however, the application of modern science has brought it to a higher level since the 1970s and '80s. New technologies, especially advances in DNA analysis, are available for detectives and criminologists to use in solving crimes and apprehending offenders. The science of bloodstain pattern analysis applies scientific knowledge from other fields to solve practical problems. Bloodstain pattern analysis draws on the scientific disciplines of biology, chemistry, mathematics and physics. History Gary Dotson. Gary Dotson (born circa 1957) is an American man who was the first person to be exonerated of a criminal conviction by DNA evidence. In May 1979, he was found guilty and sentenced to 25 to 50 years' imprisonment for rape, and another 25 to 50 years for aggravated kidnapping, the terms to be served concurrently.
This conviction was upheld by the appellate court in 1981. In 1985, the accusing witness recanted her testimony, which had been the main evidence against Dotson. He was not exonerated or pardoned at that time, but due to popular belief that he was a victim of a false rape accusation, Dotson went through a series of paroles and re-incarcerations until DNA evidence proved his innocence in 1988. Dotson was subsequently cleared of his conviction. Personal background Gary E. After his first release from prison in 1985, Dotson married Camille Dardanes, a woman who had come to know him during the hearings following his conviction.

Forensic Tools: What’s Reliable and What’s Not-So-Scientific. For years, American TV shows have featured crime scene investigators using forensic evidence to solve grim murders.
Firearms/Tool Mark Examination. Firearms Identification Firearm identification deals with the comparison analysis of projectiles and cartridge cases found at crime scenes to submitted suspect firearms. The basis of firearm identification is in the microscopic individual characteristics caused during the manufacturing process. Additional imperfections may arise from use, abuse, wear, and corrosion. These imperfections caused by manufacture or over time are what make the tool surfaces in firearms unique. Firearm examiners can also analyze for distance determinations, operability of firearms, and serial number restorations. Firearm Image Database. The Science Behind Firearm and Tool Mark Examination. By Nancy Ritter Study finds less than 1.2 percent error rate in matching bullets fired from Glock semiautomatic pistol barrels to the actual firearm.

89 90. The Labyrinth of Human Remains: The Dead Body in Public Display As a ‘museumoholic’, I find museums one of the best places to visit. Having visited many museums and exhibits around the world, I’ve always being fascinated by the history behind each exhibit – a tool of an ancient farmer or an old medical device. A few weeks ago I visited ‘Body Worlds’, the exhibition of real human bodies, which took place in Newcastle, UK, at the Life Science Centre.
On the way back to my hotel I was thinking that this was indeed an intriguing way to explore the history, philosophy and science of human anatomy; but should we exhibit the human body or human body remains? We all agree that museum exhibits are vital components in the construction of knowledge. Exhibits not only reflect beliefs and values but also generate display styles influencing the public’s perception in several ways. Forensic entomological decomposition. Medicolegal entomology is a branch of forensic entomology that applies the study of insects to criminal investigations, and is commonly used in death investigations for estimating the post-mortem interval (PMI). One method of obtaining this estimate uses the time and pattern of arthropod colonization. This method will provide an estimation of the period of insect activity, which may or may not correlate exactly with the time of death. While insect successional data may not provide as accurate an estimate during the early stages of decomposition as developmental data, it is applicable for later decompositional stages and can be accurate for periods up to a few years. Decomposition A decaying carcass provides "a temporarily, rapidly changing resource which supports a large, dynamic arthropod community.
