Criminalistics case review

Forensics in antiquity The ancient world lacked standardized forensic practices, which aided criminals in escaping punishment. Criminal investigations and trials heavily relied on forced confessions and witness testimony.

However, ancient sources do contain several accounts of techniques that foreshadow concepts in forensic science that were developed centuries later. Song Ci ruled regulation about autopsy report for court, [8] how to protect the evidence in the examining process, the reason why workers must show examination to public impartiality.

He realized it was a sickle by testing various blades on an animal carcass and comparing the wound. Flies, attracted by the smell of blood, eventually gathered on a single sickle. In light of this, the murderer confessed.

For example, the book also described how to distinguish between a drowning water in the lungs and strangulation broken neck cartilagealong with other evidence from examining corpses on determining if a death was caused by murder, suicide or an accident.

In ancient India[14] some suspects were made to fill their mouths with dried rice and spit it back out. Similarly, in ancient Chinathose accused of a crime would have rice powder placed in their mouths.

It is thought that these tests had some validity[ citation needed ] since a guilty person would produce less saliva and thus have a drier mouth; the accused would be considered Criminalistics case review if rice was sticking to their mouths in abundance or if their tongues were severely burned due to lack of shielding from saliva.

In 16th-century Europe, medical practitioners in army and university settings began to gather information on the cause and manner of death. Two examples of English forensic science in individual legal proceedings demonstrate the increasing Criminalistics case review of logic and procedure in criminal investigations at the time.

Inin LancasterJohn Toms was tried and convicted for murdering Edward Culshaw with a pistol. When the dead body of Culshaw was examined, a pistol wad crushed paper used to secure powder and balls in the muzzle found in his head wound matched perfectly with a torn newspaper found in Toms's pocket, leading to the conviction.

She had been drowned in a shallow pool and bore the marks of violent assault. The police found footprints and an impression from corduroy cloth with a sewn patch in the damp earth near the pool. There were also scattered grains of wheat and chaff. The breeches of a farm labourer who had been threshing wheat nearby were examined and corresponded exactly to the impression in the earth near the pool.

James Marsh was the first to apply this new science to the art of forensics. He was called by the prosecution in a murder trial to give evidence as a chemist in The defendant, John Bodle, was accused of poisoning his grandfather with arsenic-laced coffee.

Marsh performed the standard test by mixing a suspected sample with hydrogen sulfide and hydrochloric acid. While he was able to detect arsenic as yellow arsenic trisulfidewhen it was shown to the jury it had deteriorated, allowing the suspect to be acquitted due to reasonable doubt.

He combined a sample containing arsenic with sulfuric acid and arsenic-free zincresulting in arsine gas.

The gas was ignited, and it decomposed to pure metallic arsenic, which, when passed to a cold surface, would appear as a silvery-black deposit. He first described this test in The Edinburgh Philosophical Journal in He noticed a flaw in the bullet that killed the victim and was able to trace this back to the mold that was used in the manufacturing process.

The French police officer Alphonse Bertillon was the first to apply the anthropological technique of anthropometry to law enforcement, thereby creating an identification system based on physical measurements.

Before that time, criminals could only be identified by name or photograph. Although his central methods were soon to be supplanted by fingerprinting"his other contributions like the mug shot and the systematization of crime-scene photography remain in place to this day.

While working for the Indian Civil Servicehe began to use thumbprints on documents as a security measure to prevent the then-rampant repudiation of signatures in In at Hooghly near KolkataHerschel instituted the use of fingerprints on contracts and deeds, and he registered government pensioners' fingerprints to prevent the collection of money by relatives after a pensioner's death.

Henry Fauldsa Scottish surgeon in a Tokyo hospital, published his first paper on the subject in the scientific journal Naturediscussing the usefulness of fingerprints for identification and proposing a method to record them with printing ink.

He established their first classification and was also the first to identify fingerprints left on a vial. Having been thus inspired to study fingerprints for ten years, Galton published a detailed statistical model of fingerprint analysis and identification and encouraged its use in forensic science in his book Finger Prints.

He had calculated that the chance of a "false positive" two different individuals having the same fingerprints was about 1 in 64 billion. Juan Vucetichan Argentine chief police officer, created the first method of recording the fingerprints of individuals on file.

Inafter studying Galton's pattern types, Vucetich set up the world's first fingerprint bureau. In that same year, Francisca Rojas of Necochea was found in a house with neck injuries whilst her two sons were found dead with their throats cut.

Rojas accused a neighbour, but despite brutal interrogation, this neighbour would not confess to the crimes.Criminalistics: An Introduction to Forensic Science (12th Edition) [Richard Saferstein] on rutadeltambor.com *FREE* shipping on qualifying offers.

Forensic science is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure. The case would be decided in favor of the individual with the best argument and delivery.
