Phoenix resident Mariano Villegas was shot by a Glendale police officer on May 3 and later died after police said he broke into a home at 59th and Northern avenues and barricaded himself in the garage, said Officer Tiffany Ngalula with the Glendale Police Department. The officer who discharged his weapon has been placed on administrative leave, which is standard practice in this situation. The investigation is ongoing. The incident began when patrol officers responded to a burglary alarm call. The alarm company also notified the homeowner, who contacted a family member to respond to check on the home. The family member arrived prior to police and located an unknown adult male inside of the property. Officers arrived on scene and could hear a car horn going off inside the garage. They located the suspect barricading himself inside a vehicle parked in the garage. The suspect shouted to officers they were going to have to shoot him.Â
