Crime scene investigation requires the handling all types of potentially hazardous material‚ from blood and other physical evidence collected at the scene to the chemicals and other materials used by technicians as they perform their jobs. Failure to follow established safety and health procedures regarding the handling and disposal of hazardous material exposes crime scene technicians and others to a variety of risks. Technicians collecting evidence at crime scene must handle a range of biological

cellular respiration is taking place at the same time‚ consuming oxygen‚ the rate of which the discs rise is an indirect measurement of the net rate of photosynthesis. Aim: To find out if light affects the rate of photosynthesis through an investigation with leaf discs of a spinach leaf. Hypothesis: If the light source is removed or becomes limited‚ then it will take much longer for the leaf disc to rise as cellular respiration will no longer be taking place as part of the equation for photosynthesis

Serial Arsonist Conducting an arson investigation is a straightforward affair. The first thing to do is determine if the crime committed was actually arson‚ as arson has a strict definition. This can be especially difficult if the arsonist is skilled at his craft‚ and assume it’s a he because 94% of arsonists are young males (Baker‚ 2005). After investigating the scene and determining it was an arson‚ the next step is to determine what kind of arson it was‚ mass arson‚ serial arson‚ or spree arson

these results as I believe the more Magnesium there is the more Oxygen it will take on to form the Magnesium Oxide and so believe the results should gradually get heavier and heavier as the Magnesium gets heavier and heavier. The equation for this investigation would be Mg + O2 MgO which would balance as 2Mg + O2 2MgO. This is done as the Oxygen has two molecules which would need two Magnesium molecules to balance it out.

Autopsies are vital to homicide investigations as they are the examination of a corpse by dissection and evaluation to determine the cause‚ mechanism‚ and manner of death. Geberth’s Practical Homicide Investigation does an excellent job in explaining these concepts. Cause of death is anything that is resulted in an individual to have died‚ which can be caused by an injury‚ illness‚ or anything that could cause harm to the body (Geberth‚ 2015‚ pg 815). Examples of causes of death are people dying
