On Friday, May 8, 2026, just after 4:30 a.m., Sacramento Police officers responded to reports of a burglary in progress at a business in the 8500 block of Thys Court. Additional calls received also reported a shooting. Responding officers located an adult male burglary suspect with at least one gunshot wound. Despite lifesaving measures, the suspect was pronounced deceased on scene by Fire personnel. During the investigation, an additional adult male burglary suspect arrived at an area hospital with at least one gunshot wound and was reported to be in stable condition. A security guard for the business that was believed to have shot the burglary suspects, remained on scene and was detained by officers.
