A man was shot and killed in a secure facility by a watch guard Saturday night, according to Alaska State Troopers. 

At 10:21 p.m. the troopers received a call reporting that  Jayson Vinberg, 30, was shot at a secure facility in Kodiak. 

A guard inside the facility saw Vinberg trespassing and tapping on the windows of a building with a knife, according to a trooper report of the incident.   

The duty officer reportedly told Vinberg that he needed to leave the premises, and exited the building to confirm that Vinberg was leaving.

Instead of leaving, Vinberg started to walk toward the officer brandishing a knife. 

According to the report, Vinberg failed to obey the duty officer's repeated commands to stop walking toward him. 

According to the press release, the officer shot Vinberg with a handgun. 

Responding medics declared Vinberg dead. Kodiak troopers initially responded to secure the scene. On Sunday, Alaska Bureau of Investigation officials  responded from Anchorage and assumed case responsibility. 

This investigation is being conducted as a joint investigation between the Alaska Bureau of Investigation and the Naval Criminal Investigative Unit. 

The press release did not state where the facility was located. 

The duty officer's name won't be released until after consultation with the Alaska US Attorney's Office and Naval Criminal Investigative Unit is complete.
