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) (and ultimately provide justice for those who have been murdered). 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 these cold cases. These investigators have been either retired troopers or former police officers. Since inception, the highly experienced and capable investigators who have been assigned to in this unit have also acted as a ready resource for mentoring less experienced personnel within AST.

The CCIU is housed within AST’s Alaska Bureau of Investigation and works closely with state prosecutors and police agencies across Alaska. Furthermore, these investigations, frequently lead to travel to the Lower 48 in order to gather evidence and conduct interviews. Coordination across jurisdictions is a key factor in successfully investigating these cases.

In addition to the cold cases from AST jurisdiction, the CCIU can assist and conduct investigations, upon request, from local police agencies. Over the years, this unit has gained increased respect within the Alaska law enforcement community and as a result, requests for assistance began to come in from various local police departments who do not have the resources necessary to carry out intense or complex investigations.

Recently, the CCIU has had several major successes. The two most recent being the arrest of Steven H. Downs for the 1993 murder and sexual assault of Sophie Sergie; and the arrest in connection to the 1978 murder and sexual assault of 16-year-old Shelley Connolly.

These cases demonstrate AST’s ongoing commitment to successfully resolving cold cases. Often advancements in forensic science provide for new and additional avenues for investigators to pursue which were previously unavailable to law enforcement. As forensic science continues to evolve and expand, we will utilize these advancements to provide justice for victims and their families---no matter how cold the case.
