  16. Statute of Limitations • Laws that set time limits on how long you have to file a "civil" lawsuit, like a personal injury lawsuit, or how long the state has to prosecute someone for committing a crime. • Time limits usually depend on the legal claim or crime involved in the case. • Vary from state to state

  19. Identifying Evidence • Every crime scene needs to be treated on an individual basis. • Certain types of evidence are likely to yield significant results in ascertaining the nature and circumstances of a crime. • Responsibility of the investigator to be familiar with • Recognition, collection, and analysis of items • Laboratory procedures and capabilities

  26. DO NOW DEC 16 • Evidence has been found at a crime scene being worked by two different police departments. The first department on scene collects a number of pieces of evidence.

  31. DO NOW ANSWERED DEC 17 • The evidence will be removed from the trial as per a judge’s ruling. • The jury will be instructed to disregard this evidence. • This also opens the door for the defense to question other pieces of evidence in the trial and may place doubt in the minds of the jurors as to the scientific credibility of the prosecution’s case. • There is a strong possibility that the suspect would be found not guilty of the most serious charges.
