The Alaska Special Investigations Brochure is a type of informational document produced by the Alaska State Troopers that provides information on special investigations conducted by the agency. It contains details on the different types of investigations handled by the Alaska State Troopers, such as criminal investigations, missing persons cases, cold cases, and more. It outlines the steps taken in an investigation, as well as the tools used to assist in an investigation. Furthermore, it also provides information on the types of evidence needed to successfully complete an investigation. There are two types of Alaska Special Investigations Brochures: the standard brochure and the online brochure. The standard brochure is a printed document that can be requested from the Alaska State Troopers and is available in both English and Spanish. The online brochure is an interactive document that can be found on the Alaska State Troopers website and contains the same information as the printed brochure.
