One of the most powerful parts of a case against a criminal can be the forensic evidence that is collected and presented. Dramatic breakthroughs in both the scientific and technological fields have greatly impacted the criminal justice system.

Imagine that a recent crime wave has swept your city. You came home last night to find that your home had been burglarized. Understandably, the police and crime lab are overworked and in need of help. Physical evidence (meaning any materials at the scene of the crime that could be valuable to a criminal case) was collected by crime scene technicians at your residence and from a possible getaway car. Review theevidence that was collected from the crime scene. You will need to complete the Assignment template provided after considering the following information:

• Choose three pieces of evidence that were collected from the crime scene to examine in detail.
• Define the physical properties of the evidence collected. Also include any biological, chemical, or other characteristics of the data that would be important to the investigation.
• Explain what specific tests would be performed on the evidence and what information can be extrapolated from this evidence
• Hypothesize how the evidence could be used in the investigation and at a trial.

Note that although this is largely a hypothetical investigation, the description of a material and how it is tested will be factual and you will need to conduct research using the PG Library to identify reliable sources. The final results and importance of the evidence in an investigation will be up to your interpretation and will be largely hypothetical.

Choose three pieces of evidence from the list presented above and complete the questions in the

Name: ______________________________

Course and Section: ___________________ Instructor: ___________________________

Choose three pieces of evidence from the list presented and complete the questions in the table below.

	Sample 1 Evidence:	Sample 2 Evidence:	Sample 3 Evidence:
Analyze the evidence and the physical properties of the material. Key properties such as color, density, chemical or biological composition should be discussed.
Describe how this evidence was correctly collected from the scene.
Necessary tests to be performed on this type of sample.
Hypothetical results recorded. Imagine that the results came back from the lab. Describe what type of results you would expect for each piece of evidence. You may have to be creative and decide if the lab testing reveals more about the crime or the criminal or not.
Apply the hypothetical results from the evidence collected to the investigation and include discussion about how the results could influence a decision in a trial setting.
