  2. Careers in Criminal Justice • Chapter 5: Forensic Science • Having a witness to a crime is valuable for the successful prosecution of a case. • Gaining a confession from the suspect is another key component. HOWEVER • Neither of these is good enough to convict the defendant of the crime all by itself. • The days of routinely convicting innocent people have been over for quite some time. Sage Publications Inc. 2

  3. Careers in Criminal Justice • Chapter 5: Forensic Science • As we develop more technology and discover better methods of manipulating evidence, more is expected. • Today, successful prosecution of a case depends largely on physical evidence that is properly collected, tested, and presented. • DNA technology has become one of the most effective forensic tools law enforcement uses to convict suspects of certain crimes. Sage Publications Inc. 3

  4. Careers in Criminal Justice • Chapter 5: Forensic Science DNA • DNA can be found in blood, semen, hair, saliva, sweat, skin cells, vomit, tears, earwax, and feces. • A drop of blood the size of a pin head is enough to identify a suspect. • Because such small samples can be used, crime scenes must be cautiously searched and the evidence properly collected in order to preserve any evidence available. • The materials must be properly tested. Sage Publications Inc. 4

  5. Careers in Criminal Justice • Chapter 5: Forensic Science DNA • A record of all those who have handled the evidence must be documented. • If comparisons are successful, the evidence must then be presented at court along with testimony from those who took part in each step of the process. • The jury would need to be educated by the expert witnesses so they would understand what the evidence corroborates, proves, or disproves. Sage Publications Inc. 5

  6. Careers in Criminal Justice • Chapter 5: Forensic Science Fingerprinting • Fingerprints remain one of the most common and consistent means for identifying suspects. • They are infallible because the crucial features never change, barring any surgeries, injuries, or diseases. • A lot of fingerprinting technology has been computerized, including a national computerized system that allows identity matches to be completed in minutes. Sage Publications Inc. 6

  7. Careers in Criminal Justice • Chapter 5: Forensic Science • Until scientists work miracles in the area of robotics, there will always be a need for humans to operate the equipment, perform necessary tasks, and testify in court. • The television show CSI may mislead viewers somewhat on the realities of forensics and crime scene work. • Nevertheless, the actual present day capabilities of what can be accomplished at a crime scene and in the lab are astounding. Sage Publications Inc. 7

  8.
