Pg+1-28+Notes

- "A crime scene is a location where an illegal act took place, from asualt to burglary to murder.." (pg 1) - Criminalistics: "application of science to the phyiscal evidence [of a crime scene]" - Criminology: The study of crime - Evidence can be found anywhere so when police force first examine the place, they make sure they don't touch anything. - You have to note specific details. Has to be left exactly like it was found. - If there is an injured person on site, the first thing you do is take care of them. Mark the perimeter. If someone if found dead, you must leave them there until the crime squad comes and investigates. - a difficult aspect of figuring out a crime, is defining it's "boundaries". - Having warrant for the crime scene is very important. Any evidence without warrant can be thrown out to help solve mystery. - Two kinds of evidence: testimonial and physical. Testimonial: comes from a person being near or at the crime scene during the crime. Physical evidence has 5 categories of it's own ( temporary, conditional, associative, pattern, trace/transfer). It's "reserved for the crime scene technicians" to identify the evidence. - Things to look for: Fingerprints, Impressions of objects, body fluids, other body items (hair, nails..ect), pieces of material like glass or plastic, weapons, and any documents. Any evidence found helps the case. - Things like bags, bottles, jars, flashlights, swabs, disposable gloves, and masks are just some items that CSI members could have in their crime kits. But all kits are different, depending on what they are going to be used for. - Anthropologists: examine bones and identify forensic details. - Ballistics expert: has knowledge about firearms - Botanist: studies plant growth - Dactyloscopist: analyzes fingerprints - Entomologist: developmental stages of insects - Geographical profiler: uses computers to figure out where a serial offender is. - Linguist: analyzes messages to get deeper details from it. - Odontologist: studies teeth - Serologist: analyzes body fluids. - Coroner's direct things like autopies, identifications of victims, violent death statistics. - Photographers use different things to take multiple pictures of one thing. - photographs need to link ideas of the scene to each other, and give good overviews. Also close up pictures are important to know about the crime after it is no longer there. - Evidence must be labeled, and kept to last throughout the investigation
