Often said to be speaking for the dead, forensic pathologists can establish a cause and a rough time of death and can often provide clues regarding the physical characteristics of the person or persons responsible for the crime. Argon lasers, the most common laser used at crime scenes, emit a stream of amplified light waves that cause physiological fluids and trace evidence--such as semen, fibers from clothing, car upholstery and rugs, and the chemicals left behind by fingerprints--to fluoresce in various colors, forensic scientists said.

RCTs provide the highest degree of confidence that observed effects are the result of the program and not of other factors. Fingerprint analysis resulted from the groundbreaking theory established by Henry Faulds and William James Herschel from the uniqueness of fingerprints. Chemical tests of various kinds are used for ink comparisons. Procedure. However, until now police scientists have been able to discover the traces of blood thanks to reagents such as luminol, phenophthalene or the human haemoglobin Despite all developments, any investigation still requires a human brain to decipher and rationalize the events of an incident scene.

Eventually, the murderer confessed when the smell of blood caused flies to gather on his sickle. Even so, the researcher concludes that washing the materials with products containing active oxygen does not eliminate the blood completely because brown traces remain, but it certainly does prevent detection by means of current tests, "and it is advisable to take account of this when using these methods in criminalistic research". Forensic scientists spray luminol onto surfaces at crime scenes to detect invisible blood stains.
