Alaska State Troopers and Fairbanks police responded to a reported sighting at midday Thursday of a man wanted on murder charges in a weekend stabbing, prompting security measures at area schools, but said he was not found.

Megan Peters, a troopers spokeswoman, said in an online dispatch that a sighting of Greg Beasley was reported Thursday in the Chena Pump Road area. Beasley, 27, is being sought in the death of 47-year-old Guy Mitchell Yazzie, who was found suffering from stab wounds to his heart, torso, legs and left arm at a 17th Avenue home late Sunday.

“As a precaution schools in the area were notified,” Peters wrote. “Troopers responded to conduct both a ground and an aerial search. No signs of Beasley were located and troopers have pulled out of the area.”

Police spokeswoman Yumi McCulloch said in a Thursday message that the sighting of Beasley was ultimately “not confirmed.”

Sharice Walker, a spokeswoman for the Fairbanks North Star Borough School District, said troopers briefly asked that the Wood River Elementary School be placed in lockdown at 11:10 a.m. At their own discretion, district officials secured outer doors at three other schools – University Park Elementary School, as well as West Valley and Hutchinson high schools – until about noon, when troopers lifted their alert regarding Beasley.

Fairbanks police consider Beasley armed and dangerous, and ask that anyone with information on his whereabouts contact Detective Peyton Merideth at 907-450-6553 or the Investigations Unit at 907-450-6550.
