Casa Grande police have identified the suspects and victims in a quadruple killing attributed to domestic violence, saying that one of the victims was the estranged wife of one of the suspects.

Police say 31-year-old Alec Javier Perez and 22-year-old Rodney Ortiz Jr. remain jailed after being arrested Thursday on suspicion of four counts of first-degree murder.

The victims are identified as 32-year-old Justin Allen Yates, 27-year-old Jose Martin Aguilera, 31-year-old Connie Carrera and 29-year-old Crysta Proctor.

Police said Proctor was the estranged wife of Perez. Their public social media posts show the couple had a tumultuous relationship, had married earlier this year and recently separated.

Mary Lou Rodriguez, the mother of Perez, said in a written statement that she loves her son but does not condone or accept violent behavior. Rodriguez expressed condolences to the victims' loved ones, saying she feels shock, horror and dismay. Rodriguez declined to be interviewed.

Police say the case has been submitted to the Pinal County Attorney's Office for review.

A police department spokesman, Officer Thomas Anderson, says he doesn't know whether the suspects have attorneys who could comment on the allegations.
