SCIENTIFIC CRIME INVESTIGATION VS. SPECIAL CRIME INVESTIGATION Scientific crime investigation is an investigation with the application of sciences or scientific method for systematic crime solution‚ acquiring new knowledge‚ or correcting and integrating previous knowledge for investigating crimes. A scientific method consists of the collection of data through observation and experimentation‚ and the formulation and testing hypotheses. Scientific method follows laws of logic. While special crime

Some reasons that a homicide investigation starts at the primary crime scene is mainly because the police are usually called to this location by the person who discovers the body‚ or‚ a witness to the crime‚ but it could also in some cases even be the victim. In homicide cases‚ the location where the body is discovered hold a great deal of physical evidence and serves as a starting point for the beginning of an official investigation. At this point it is safe to say that it is important to assume

upon whatever it touches‚ even if it is the minutest amount‚ simply put as “Every Contact leaves a trace‚” Locard (1923). This is commonly known as Locard’s Exchange Principle. He believed that in circumstances such as a crime‚ his principle could be used to find evidence of who and perhaps even how that crime was committed by finding small materials‚ either physical or chemical at the scene of the crime that would directly link back to the offender. Fingerprints are a classic example of what could

Another ethical issue surrounding a digital forensic investigation is how personal information about a suspect can create a bias for the investigator. Bias is a very large issue during a forensic investigation‚ it can change how well an investigator performs and how they will use the evidence to influence a case. During every investigation an investigator will come across information about a suspect that does not involve the crime‚ but may influence the investigator’s actions. These factors can be

CHM 116 Lab Investigations of Buffers I. Purpose The purpose of this experiment was to get an understanding as to how to properly prepare chemical buffers. Also part of this experiment was to gauge the effectiveness of the buffers by measuring their pH levels in various titration solutions‚ using a pH meter. II. Procedure To start our experiment we had to prepare Buffer B‚ which was the .060 M Ammonia/Ammonium solution. Using 3.0 M ammonia‚ we had to calculate

Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool‚ dark‚ damp microhabitats such as in rotting wood‚ under rocks‚ in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes‚ crickets‚ weta and spiders living. Woodlice

to the force that is used to move the molecules through the gel. There are 2 stages to gel electrophoresis‚ separation and visualization. During separation the gel matrix is placed in an electrophoresis machine. An electric current is run through the machine and the different sized molecules form bands on the gel matrix. In visualization‚ the gel is dyed so the results become present. This is used in modern crime labs‚ figuring out DNA‚ which plays a key role in many criminal trials. The researcher

Homicide Investigation More work goes into a homicide investigation than what the media alludes to. Television shows like Law and Order‚ and CSI show an over glorified series of basic investigations as well as highly dramatic interrogation in which each homicide case is solved within a one-hour episode. In reality‚ a homicide investigation is 20 times more complex than what is aired on prime time television. Cases can take years to solve‚ and a large number remain open indefinitely. From start
