On the afternoon of February 21, 2018, violence erupted in west Phoenix near 35th Avenue and Thomas Road when a woman called police saying her husband, 39-year-old Edward Hallinan, was firing a rifle at their home. Officers later spotted Hallinan driving a truck; after he parked, a gunshot was heard from inside the cab and he fired again as police ordered him to drop the weapon. A 17-year veteran officer returned fire and Hallinan was taken to a hospital, where the Maricopa County Medical Examiner later determined his fatal wound was self-inflicted.

A police helicopter then discovered three men with gunshot wounds in the yard of the residence next door: 26-year-old Vidal Hernandez-Gutierrez, 21-year-old Francisco Javier Galindo, and 50-year-old Manuel Francisco Rodriguez Jimenez. All three were pronounced dead at the scene. Reports indicate Hallinan shot his three neighbors before the confrontation with officers, but the motive was not immediately clear.

If anyone knew Vidal, his routines, or saw activity in that neighborhood on February 21, 2018, please share what might help explain what happened that day?
