On May 19, 2023, 34-year-old security guard Adalberto Santiago was fatally shot while on duty at Preston Center Plaza in Dallas, Texas. The shooting happened at about 3:30 p.m. after Santiago confronted an individual who was attempting to break into vehicles on the second floor of the parking garage. A struggle ensued and Santiago was shot; he was taken to a hospital and later died of his injuries.

The suspect fled in a gold Toyota Camry; the vehicle was later found in a closed business parking lot in the 2200 block of North Cockrell Hill Road. Dallas police identified and arrested 17-year-old Antwon Osborne on May 23 in Nevada. Osborne was extradited to Texas and has been indicted by a grand jury on a murder charge. At the time of the shooting, Osborne was out on bond on prior charges including theft, evading detention, and unlawful carrying of a weapon.

Santiago’s colleagues and patrons remember him as a proud Puerto Rican who took his security duties seriously and often greeted people warmly. If anyone knew Santiago or has information about the case, please come forward to share what you know.
