In the early morning hours of May 30, 2009, three people forced their way into the Flores home in Arivaca, Arizona, while posing as law enforcement officers looking for fugitives. The intruders—identified as Shawna Forde, Jason Eugene Bush, and Albert Gaxiola—were reportedly seeking money and drugs to finance an anti-immigrant vigilante group led by Forde.

When the attackers did not find what they expected, they opened fire. Raul Junior Flores, 29, was shot and killed inside the house. His nine-year-old daughter, Brisenia Ylianna Flores, was also killed. Raul’s wife, Gina Gonzalez, was shot multiple times but survived by pretending to be dead; after the first exit of the intruders she called 911, retrieved her husband’s handgun, and later exchanged fire with the assailants, wounding Bush in the leg.

Investigators tied the three to the crime using Gonzalez’s eyewitness identification, the recovery of Gonzalez’s jewelry, and text messages and recorded conversations about planning the invasion. By 2011 all three perpetrators had been convicted; Forde and Bush received death sentences and Gaxiola was sentenced to life without parole. Who in Arivaca that night might still have information about the group’s activities or planning?
