Bear River Tribal Police officers were first to arrive and found a male and a female dead at the scene, the sheriff’s office said. A third victim, a female, was hospitalized, where she later died from unspecified injuries. Two uninjured juveniles were also found inside the residence and placed into safe custody.
The causes of the victims’ deaths were not released, pending autopsy results. The victims were identified as Nikki Dion Metcalf, 40; Margarett Lee Moon, 40; and Shelly Autumn Mae Moon, 16.
Mauricio Johnson and Von Eric Keener, 46, were in the car. Johnson was arrested on a warrant for murder, and Keener was taken into custody on a parole warrant, according to the Humboldt County Sheriff’s Office. The female subject in the other car was also expected to be charged.
Johnson, the only individual identified as a suspect in the triple homicide, was held without bail. The investigation was ongoing.
