Cold Case Investigation Unit

The Cold Case Investigation Unit (CCIU) was formed in 2002. This unit’s primary function is to investigate unresolved homicide cases previously investigated by the Alaska State Troopers (AST). The cases being reviewed and investigated by the CCIU date as far back as 1961.  Recognizing the time-consuming nature and complexity of many of these cases, the department initiated a program of hiring experienced investigators to work on these cold cases. These investigators have been either retired troopers or former police officers. Since its founding, the highly experienced and capable investigators who have been assigned to this unit have also acted as a ready resource for mentoring less experienced investigators within AST.

The CCIU is housed within AST’s Alaska Bureau of Investigation and works closely with state prosecutors and police agencies across Alaska. The CCIU investigates any homicide or long-term suspicious missing person case that was originally investigated by the Alaska State Troopers and remains unsolved for three years or more after being reported, and has no viable unexplored investigatory leads. Cases may be designated as cold cases earlier if all leads are exhausted and approved by the ABI Commander. In addition to the cold cases within AST jurisdiction, the CCIU can assist and conduct investigations, upon request, from local police agencies with approval from the Colonel of the Alaska State Troopers. Cases may be removed from cold case status if the statute of limitations of the alleged crime(s) has expired, or if all suspects and witnesses are deceased and there is limited physical evidence.

DPS proactively publishes a quarterly list of all missing Alaska Natives, American Indians, and individuals whose race law enforcement does not know. This list includes the circumstances of each missing person's case, including identifying any as suspicious. This report is available online here. 

If anyone has information regarding any of the unresolved homicide cases, please contact the Alaska Bureau of Investigation (ABI) at 907-269-5611.
