Tips for Law Enforcement

  • When Submitting a Service Request Form or an Evidence Custody Form — The case agent or officer should be as concise and thorough as possible. These forms are used to make decisions about the request, therefore, any vague or ambiguous terminology may make it more difficult to interpret or understand what services are needed. As a result, delays in processing the request may occur.
  • Turning On or Accessing a Computer — Indicate on the Service Request Form if you or anyone else in the chain of custody attempted to turn on or access the computer prior to submittal. This is very important information for the Examiners to have.
  • Search Warrants — If a field service request is pursuant to a search warrant, include a copy of the warrant with the Field Service Request form. Likewise, if the service request is a result of a consensual search, a copy of the agency's "consent for search" form must be included. Failure to include this documentation may cause a delay in processing the request.
  • Handling Sensitive Equipment — Always use extreme caution or take precautionary measures such as grounding the static electricity before touching any of the internal components of the computer or handling sensitive electronic equipment. For example, if the internal workings of a computer are exposed, the equipment could be damaged by a buildup of static electricity that is held by the human body. (Walking across a rug can produce a static electricity voltage of up to 12,000 volts.) The hard drive is especially susceptible to static electricity, even if it is exposed to a small amount of voltage, while a microchip can be damaged with as little as 500 volts of static electricity. If you're unsure about how to handle the equipment--defer to a professional.
