On October 5, 2017, a shooting at a home near Pinal Avenue and McMurray Boulevard in Casa Grande, Arizona, killed four people, including 32-year-old Justin Allen Yates. Police were sent after a 911 call about gunfire and found Yates, Connie Carrera, 31, Crysta Proctor, 29, and Jose Martin Aguilera, 27, deceased inside the residence.

Investigators treated the attack as a targeted act rooted in domestic strife; public social media posts show Crysta Proctor had been married to, and separated from, one of the men later identified as a primary suspect. Neighbors reported seeing two men fleeing the duplex. Alec Javier Perez, 31, and Rodney Ortiz Jr., 22, were arrested and charged with four counts of first-degree murder, and the case was submitted to the Pinal County Attorney’s Office. A woman identified as Perez’s mother issued a written statement condemning violence and offering condolences.

If anyone knew Justin Yates, the other victims, or saw activity around that duplex on October 5, 2017, please come forward with information.
