Alaska State Troopers are investigating an assault with a fillet knife in Nenana.
The Fairbanks Daily News-Miner reports 39-year-old Ralph Trinidad is charged with stabbing a man in the chest and face.
Troopers say a woman reported picking up Trinidad and the other man in Anchorage and driving them north to Nenana to find work. She says Trinidad at some point began accusing the other two of conspiring against him.
She says after reaching Nenana, Trinidad on Monday night refused to leave her van, and when the other man approached him, Trinidad stabbed him.
The injured man told troopers he punched Trinidad until he dropped the knife.
Troopers recovered a fillet knife outside the van.
Nenana is 60 miles south of Fairbanks.
