This event was the beginning of a process that is now widely used throughout forensic science. When a person dies an autopsy is normally carried out.]]> 2020-01-18 04:26:56 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433220440 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433220856 Dr. Schreyer devised the first standardized procedure in forensic medicine.

This was one of the first documented uses of physical matching. A technique that is still used today. ]]> 2020-01-18 04:34:54 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433221109 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433221673 Italian Giovanni Morgagni founded the science of pathology. 

Pathology is known as branch of medicine that deals with the laboratory examination of samples of body tissue for diagnostic or forensic purposes. ]]> 2020-01-18 04:41:56 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433221673 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222178 A Belgian physician made 
studies of rigor mortis. 

Rigor mortis is the stiffness of the body that sets in after a person dies. A person's time of death can be determined by the time that rigor mortis sets in. ]]> 2020-01-18 04:49:08 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222178 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222293 William Nichol invented the polorizing light microscope. ]]> 2020-01-18 04:50:56 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222293 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222391 First successful photograph taken. 

Photographs are an important aspect of forensic science evidence. ]]> 2020-01-18 04:52:15 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222391 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222467 In England fingerprints were first classified by J.E. Purkinje. 

Fingerprinting is now more developed but there are different patterns in fingerprints that can determine a person's identity. ]]> 2020-01-18 04:53:15 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222467 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222622 Traces of arsenic become traceable. 

Arsenic is a chemical that some people use to poison others. ]]> 2020-01-18 04:55:20 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222622 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222731 James Marsh, an Scottish chemist, was the first to use toxicology in a jury trial, specifically arsenic detection. 

Toxicology reports can determine different chemicals, drugs, alcohol levels and substances that are in a person's body at the time of their death. ]]> 2020-01-18 04:57:05 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433222731 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433223101 The first bullet comparison was used to catch a murderer, based on a flaw in the mold of the bullet. ]]> 2020-01-18 05:01:32 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433223101 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433223203 The first reliable procedures for the microscopic detection of sperm were published as well as substrate fabric characteristics.

Sperm and fabric fibers can help place people at the scene of a sexual crime or murder. ]]> 2020-01-18 05:02:49 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433223203 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433223584 German scientist Schonbein found a way to generally ID blood stains. Another scientist also invented the first testing of blood.

Blood stains on fabric can determine a person's role in a murder, as blood spatter can determine the object used to kill a person. ]]> 2020-01-18 05:08:17 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433223584 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433224437 President Theodore Roosevelt established the Federal Bureau of Investigations (FBI). 

The FBI is in charge of different aspects of forensic science from testing, to profiling, to solving high profile crimes. ]]> 2020-01-18 05:20:20 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433224437 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433224730 Fire victims in a Vienna Opera House were identified by their teeth. 

The use of dental records is widely used to identify people who are deceased and otherwise unidentifiable. ]]> 2020-01-18 05:24:06 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433224730 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433225047 American Robert Wood demonstrated the criminalistic use of the ultraviolet light. 

Ultraviolet lights are used in forensic science to show blood stains and human fluids that have been cleaned from a crime science. ]]> 2020-01-18 05:27:44 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433225047 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433225162 First time the results of a spectrographic paint analysis are admitted into evidence at a trial.

Paint analysis can place a person at the scene of a crime involving a vehicle. ]]> 2020-01-18 05:29:05 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433225162 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433225364 The first use of DNA was used to solve a crime, ultimately exonerating an innocent suspect. 

DNA is one of the highly used techniques to solve murders today. ]]> 2020-01-18 05:31:38 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433225364 dgonzales14 https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433225560 John Larson and Leonard Keeler designed the portable polygraph. 

Polygraphs have been used to determine if a person is lying about their involvement in a crime. ]]> 2020-01-18 05:34:06 UTC https://padlet.com/dgonzales14/3gca4vtr8p98/wish/433225560
