 Alaska State Trooper Aid Detachment Commander Mike Zweifel said that just before 8 a.m., 37-year-old Kristen Kenneth Requena of Kenai, who was experiencing a mental health crisis, had committed a crime and subsequently barricaded himself in an Akiski home. Requena refused repeated requests from the homeowner to leave. According to Zweifel, a newly formed special crisis unit was activated to negotiate with Requena.
