Police say a woman shot dead along with a male renter in her Phoenix home was pregnant, and the woman's estranged husband is sought on three murder charges.
Phoenix police Sgt. Armando Carbajal said Sunday that authorities in the U.S. and Mexico are seeking 47-year-old Dimas Coronado and two young brothers.
He says Amber Alerts are posted in both countries in an effort to find the two boys the couple had together.
Carbajal says police aren't sure if Coronado has 8-year-old Victor Coronado Nunez and 5-year-old Jonathan Coronado Nunez with him.
Carbajal says 24-year-old Oralia Nunez was seven months pregnant.
Renter Omar Gonzalez was also found dead at Nunez's home early Saturday.
Coronado was believed to be driving an older model light green Ford pickup truck with a white camper shell and a Chihuahua, Mexico, license plate of ZUD-71-64.
