The Kansas Bureau of Investigation (KBI) is investigating an officer-involved shooting that occurred Saturday night in Sumner County. Preliminary information indicates that at approximately 10:26 p.m. on Saturday, two officers with the Wellington Police Department arrived at the residence of 1111 E 7th St in Wellington regarding a disturbance. Officers made contact with the reporting party who indicated her boyfriend, Harley Bagby, 30 of Wellington, was inside the residence, tearing the house up. Officers were given access and made entry into the residence. As officers entered the residence, they were met by Bagby, who exited a bedroom into the hallway with a large knife. Officers gave commands to Bagby to drop the knife. Bagby did not comply. Bagby advanced toward the officers. One officer fired multiple times and struck Bagby. Wellington EMS pronounced him deceased at approximately 11:05 p.m. The officer has been placed on paid administrative leave. The KBI will conduct a thorough and independent investigation into this shooting. Once the investigation has concluded, the findings will be turned over to the Sumner County Attorney for review.
