Jacksonville Police are actively searching for 20-year-old Roy Patrick Hamilton Jr., who remains at large and is considered armed and dangerous. The search began around 4:42 p.m. on Saturday, May 23, 2026, after officers responded to a disturbance at the Sweet Union Apartments located on Highway 69 North in Jacksonville, Texas. According to law enforcement, Hamilton allegedly assaulted a woman while armed during the initial incident. Upon arrival, officers established a perimeter after multiple witnesses indicated the suspect had barricaded himself inside an upstairs apartment unit. The standoff continued for several hours, prompting the evacuation of nearby residents and a thorough search of adjacent units. By 9:45 p.m., Jacksonville Police Chief Steven Markasky confirmed that the immediate standoff had been terminated, but Hamilton had successfully evaded capture and his exact whereabouts remained unknown. Investigators are currently following up on multiple leads and conducting additional searches in the surrounding area to locate the suspect. Authorities emphasize that Hamilton should not be approached under any circumstances due to the ongoing threat he poses to public safety. Residents who were temporarily displaced have since been permitted to return to their homes. The Jacksonville Police Department is urging anyone with information regarding Hamilton’s location to come forward immediately. The public is advised to avoid contact with the suspect and to direct all tips to the department’s dedicated tip line at 903-586-2546. Law enforcement continues to treat this as an active manhunt and has not released further details regarding potential charges beyond the initial assault allegation.
