A forensic science technician is an occupation that many people have not heard of. Most people think of it as what is seen on the television show CSI‚ but there is a lot more to the job than what it pictures. A forensic scientist collects data from a crime scene and takes it back to the lab to fit the missing pieces together. This is a very important job as a forensic scientist also helps with deciding if someone is guilty or not in an investigation. Throughout this paper I will be discussing what

The alcohol drew heat from the body as it’s evaporating thus creating a greater heat loss and temperature change. 3 Skin Prints Different areas of the skin have different skin prints. A fingerprint has a loop design‚ whereas the skin print of a palm is straight and linear. The lines of a wrist print are interconnected and narrow. The skin print of an elbow is unorganized‚ in which the lines go in many different directions forming irregular

Individual Work 1 What was Francis Henry Galton ’s major contribution to forensic science? Francis Henry Galton’s major contribution to forensic science was conducting the first official study of fingerprints and to this day we still use his taxonomy of prints! He published a book in 1892 that had the first statistical proof that supported his message of personal identification. He also invented the scientific meteorology. Who is known as "the father of forensic toxicology" and why? A Spaniard

career path that I should follow. A forensic scientist has many different responsibilities. Forensic scientists must collect data from a crime scene and take it back to the lab. Then they will observe their collected data and run tests on it to find fingerprints or other evidence. After finding out as much as possible‚ they will then send the samples back to the investigators‚ along with the evidence and what they have found. Forensic

evidence that are found at a crime scene and can be used in cases. However‚ the weight of a given piece of evidence is ultimately decided by a jury. The types of physical evidence include but are not limited to; blood‚ semen‚ saliva‚ documents‚ hair‚ fingerprints‚ paint‚ fibers‚ and drugs. The collection of evidence must be thorough enough to include as many pertinent clues as possible‚ but selective enough not to delay the laboratory.

Clues‚ and Investigation” by Andrea Campbell‚ forensic evidence is the most important evidence that is presented during a trial. In addition‚ forensic evidence is the method in which crime investigators collect evidence such as blood samples‚ fingerprints‚ and other forms of DNA. Forensic evidence uses science and hard evidence to determine the innocent and the guilty within a trial. This kind of evidence can exclude suspects and identify other suspects. Forensic evidence is the most accurate

cases are being tried in court. Studies show that juries are calling for more forensic evidence and may be finding individuals not guilty when there is not a great deal of forensic evidence. Juries are also increasingly using terms (such as latent fingerprints or mitochondrial DNA) found on these programs‚ even when they are not used in the trial. Finally‚ juries are increasingly expecting to see the complex tests and techniques seen on TV‚ even when they are not available or reasonable given the court

scattered off a material most of it is scattered in its original wavelength but a small amount is scattered in a different wavelength (2013). A microscope is used to collect the light giving a Raman spectrum‚ which gives a characteristic vibrational fingerprint (2013). This can then be compared to various types of lipsticks (2013). Currently more research is being conducted into applying the same method on other types of cosmetic evidence‚ such as eyeliners‚ and skin creams (2013). This recent advancement
