Which passenger safety devices were used prior to the collision; <br />ii. Which passenger protection devices were deployed during the <br />collision; <br />iii. The change in velocity of the vehicle prior to and shortly after <br />impact; and <br />iv. The use of brakes. <br />v. Note: A search warrant may be necessary to search the Airbag <br /> Control Module. See also Department policy 41M – <br /> Search and Seizure. <br /> <br />c. Experts: From time to time, follow-up crash investigations may require <br />special skills and technical assistance beyond that available from <br />department personnel. When necessary, the department shall utilize <br />outside expert and technical assistance (i.e., photographers, surveyors, <br />mechanics, physicians, and collision section specialists). A supervisor <br />shall make the decision of when to call in an outside crime scene <br />specialist. <br /> <br />E. Investigations of Hit and Run Crashes <br /> <br />1. The elements of hit and run: the defendant goes away having operated a <br />motor vehicle upon any way or in any place to which the public has a right of <br />access, or any place to which members of the public have access as invitees <br />or licensees, after knowingly colliding with or otherwise causing injury to any <br />person, or injury to any other vehicle or property without stopping and making <br />known his/her name and residence and the registration number of his/her <br />motor vehicle. <br /> <br />2. On-Scene Duties <br /> <br />a. Officers shall first make provisions for the medical treatment of the victim, <br />if necessary. Investigating officers should follow-up on the condition of <br />victims after they are transported to a hospital if there is any possibility <br />that the victim could die of his/her injuries, thus making a charge of motor <br />vehicle homicide possible. <br />b. Officers shall obtain the best possible description of the operator and <br />his/her vehicle from the victim and available witnesses. The following <br />information about the vehicle is important: <br /> <br />i. Make; <br />ii. Model; <br />iii. Year; <br />iv. Color; <br />v. Extent and location of damage; <br />vi. License plates (including partial numbers or letters); <br />vii. Unusual markings or equipment (including school, fraternal or <br />organizational signs or stickers, roof racks);
