CRJS365-IP3NameClassDateProfessorEvidence Collection As a crime scene investigator for a homicide there are several types of evidence that must be photographed, logged, and recovered from that scene. In order to ensure this happens and evidence is not damaged or lost the crime scene must first be secured so evidence can be preserved. Once the crime scene investigator arrives on the scene they will conduct a walk through in order to locate any forensic evidence. The types of evidence that has been located during the walk through of the crime scene includes blood evidence that has dried on the floor, handgun and shells by the body of the deceased, and several hairs in the hands of the murder victim. It is essential to have the necessary knowledge to ensure that evidence is properly collected to ensure its validity in a court of law. If the evidence collection process becomes called into question the result could be the exclusion of the evidence from the court process. If evidence is excluded the guilty offenders could go free. Evidence collection at the crime scene is essential to developing evidence of what has happened and who is responsible for the crime. Many criminal cases have been proven without forensic evidence, in the 21st Century the jury has a high expectation that there will be physical evidence proving the guilt of the offender left at the crime scene. Blood stains can be essential to solving a criminal case. Blood stain
