PHOENIX — The Latest on two killings and two missing boys in Arizona (all times local):

2:50 p.m.

Phoenix police say a pickup truck belonging to a man sought for questioning in the disappearance of his two young sons and the killing of the boys' mother and another person has been found about six blocks from the home of the victims and the boys.

Sgt. Armanda Carbajal says a person reported the location of the truck but there was no sign of the 5- and 8-year-old boys and their father, 47-year-old Dimas Coronado.

The boys are the subject of an Amber Alert issued Saturday after the mother and an adult male housemate were found fatally shot earlier in the day.

The alert said Coronado might be taking the boys to Mexico, but Carbajal says police don't know where he and the boys are or whether Coronado now has a different vehicle.

Police have said Coronado isn't charged in the case.

10:50 a.m.

Authorities have issued an Amber Alert for two young brothers and their biological father missing since the boys' mother and a male housemate were found fatally shot in the Phoenix home where the victims lived.

The alert issued Saturday said 47-year-old Dimas Coronado may have fled to Mexico with the boys. Police want to talk to him about the case but he hasn't been charged.

Police said Coronado has a 2009 white Chevrolet Silverado four-door truck with custom rims and Arizona temporary license 43644T.

Police initially identified the boys as 8-year-old Victor Coronado Nunez and 5-year-old Jonathan Coronado Nunez but the alert later identified them as Victor Nunez-Coronado and Jonathan Nunez-Coronado.

Police spokesman Sgt. Armando Carbajal said the revised names likely reflected information newly learned by detectives.
