Alaska Bureau of Investigation

The Alaska Bureau of Investigation (ABI) is responsible for coordinating and conducting major criminal investigations within Alaska State Troopers jurisdiction.  This includes homicides, sexual assaults, sexual abuse of minors, human and sex trafficking, fraud, forgery, and computer and internet crimes. The mission of ABI focuses also on developing the investigative skills of personnel within the Department of Public Safety and building collaborative relationships with other law enforcement agencies.  ABI members also receive training and serve as polygraph examiners.  ABI also staffs and manages the missing persons clearinghouse responsible for tracking all reported missing persons cases within Alaska.

  • Provide certified instructors for crime scene investigations, motor vehicle crash investigations, interviews and interrogations, computer forensics and electronic evidence training and a variety of other training subjects such as SART and domestic violence
  • Represent the department on a variety of working groups and task forces to include human trafficking, Internet Crimes Against Children, Child Justice Act Task Force, Sexual Assault Response Team and the U.S. Attorney's Office Financial Crimes Task Force
