Leaves, seeds and pollen found either on a body or at the scene of a crime can offer valuable information regarding the timescales of a crime and also if the body has been moved between two or more different locations. The DNA evidence was used for the first time to help the criminal investigation in 1988. Forensic investigators can calculate time of death by measuring the amount and size of discoloration and comparing it with the physics behind the flow of blood. Forensic Science Fun Facts Bugs that are present in a dead body can help determine the time of death. DNA Testing Makes Mistakes [6] A “reporter” (R) dye is attached at the 5’ end of the fluorescent probe while a “quencher” (Q) dye is attached at the 3’ end. Using technology in the lab and in the field, forensic biologists collect and analyze biological evidence found on clothing, weapons and other surfaces to determine the time and cause of death. Forensic science is the application of natural sciences to matters of the law. The practicality of investigators in the past is responsible for modern scientific forensic methods. Biology Facts . 9. [10] A haplotype "is a group of alleles in an organism that are inherited together from a single parent". A forensic biologist pieces together a picture of biological evidence. 7. You Can’t Lie Through Your Teeth Computer technology has made this process a lot easier, but seasoned forensic scientists note that there is no completely foolproof statistical formula for matching fingerprints. Forensic ballistics experts can identify what type of bullet was used, its caliber, and even where it was manufactured. Besides having a useful relation with forensic, it also has something to do with biological sciences. The biggest concern about all of these SAKs, is how to go about processing all of them, especially as more and more are being found each year.[22].

Rather than taking the time and effort to teach that person how to write his name, authorities decided that thumbprints were a viable alternative to signify identity. [2] If positive, samples are collected and submitted for analysis in the laboratory, where confirmatory tests and further tests are performed. Postmortem microbiology in sudden death: sampling protocols proposed in different clinical settings. We can get DNA … They can analyze whether a gun was recently fired and whether a particular bullet was fired by a specific gun. Long before fingerprints became the norm for identification, authorities used bertillionage, an arduous process that entailed taking 11 different bodily measurements, including: height, length of the body from the left shoulder to the tip of the middle finger in a raised right arm, length of the torso from head to seat when in a seated position, length from the crown to the forehead, length between temples, length of the right ear, length of the left foot, length of the left middle finger, length from the left elbow to the tip of the left middle finger, the width of the cheeks, and the length of the left pinky.
