Frank Sambrano, 25, was found guilty on Thursday for attempting to kill an Anchorage police officer. Prosecutors say he tried to cut the officer's neck.
Sambrano's trial lasted six days, according to deputy district attorney Clint Campion.
Campion said the attempted murder charge stemmed from an altercation in June 2014, when Sambrano swung a steak knife at the officer. Police had been responding to a disturbance.
Trial evidence indicated Sambrano was living in Anchorage with family members. One of the family members called police about an incident involving Sambrano and another man, Campion said.
Police responded and told Sambrano "he needed to leave the residence to cool off" or he would be arrested for disorderly conduct, the prosecutor said. But Sambrano refused to leave.
"A police officer then informed Sambrano that he needed to put his hands behind his back," Campion said. "Sambrano responded by pulling out a steak knife and then swung the knife at the officer's head and neck."
The officer avoided injury, but Sambrano slashed the officer's uniform. Other officers who saw the attack subdued Sambrano.
Jurors heard three days of testimony and deliberated for two days. They convicted Sambrano of first-degree attempted murder and first-degree attempted assault.
Assistant district attorney Andrew Grannik tried the case.
Sambrano's sentencing was set for May 8. He faces a 99-year sentence. His court record incudes 17 misdemeanor convictions in Alaska, including seven for assault.
