The first step I would take as an investigator is to assure that the crime scene is secured and limit access to crime scene technicians and investigators on the case. (Chval, 2006) For each piece of evidence, I would have it flagged with a number, photographed, and a written description of the evidence logged to correspond to the number. (Chval, 2006)I would then have the evidence collected in the appropriate manner by a technician, places in a tape-sealed container, and signed by the technician who took the evidence across the seal.
(Chval, 2006) I would then make sure that all evidence from the scene is transported in a vehicle manned by officers to evidence storage. (Chval, 2006) The time of transport and the transporting officers’ names and ID numbers should also be logged. The same officers should move the evidence into department storage and log its entry time and date. (Chval, 2006)The clerk in the evidence storage facility should log time and date and identity of anyone who wishes access to the evidence, and should only give access to legally eligible parties.
(Chval, 2006) At trial, I would have whichever attorney is planning to introduce the evidence sign it out, and have it escorted with an officer to the courtroom. (Chval, 2006) The technician who collected the evidence should take the stand, verify the seal on the container and his/her signature under oath, break the seal, and verify that the contents match the log. (Chval, 2006) All logs should be available to verify chain of custody. (Chval, 2006)
