Casa Grande Police are searching for an unidentified suspect following a fatal shooting that occurred outside a house party in the early hours of September 20. The incident took place near the intersection of Trekell and Rodeo roads around 1:20 a.m. Security video obtained by investigators captured the sounds of 19 gunshots being fired in the area. Joseph Castro, an 18-year-old resident, was discovered in the driveway of a nearby home with multiple gunshot wounds. He was pronounced dead at the scene. Castro’s father, who had briefly left the residence to visit a gas station, returned to find his son lying in the driveway and neighbors gathering. Neighbors reported hearing the shots and seeing people fleeing the area in vehicles. Castro, who had turned 18 just two weeks prior, is described by his family as a responsible young man who held a full-time job and leaves behind a large grieving family. Authorities have not yet identified any suspects or determined the motive behind the shooting. The investigation remains active, and police are urging the public to come forward with any information that could assist in identifying the shooter. Residents with knowledge of the incident or the identity of the suspect are asked to contact Detective Brandon Garcia directly. Tips can be submitted by calling 520-840-3175 or by emailing Brandon_Garcia@casagrandeaz.gov. The Casa Grande Police Department continues to review evidence from the scene, including the security footage, as they work to bring the perpetrator to justice.
