In the pre-dawn hours of May 4, 2017, gunfire rang out in the Rivera Motel parking lot on Colfax Avenue in Aurora, Colorado. Officers arriving about 1 a.m. found 32-year-old Marquette D. Killingsworth with a gunshot wound to the chest; he was taken to a nearby hospital and pronounced dead. Investigators said it was unclear whether Killingsworth had been a motel guest or what led to the shooting, and an unrelated arrest for a nearby robbery prompted a school lockout during the early response.

Five days later, on May 9, 2017, a SWAT team arrested a suspect at an apartment in Colorado Springs in connection with Killingsworth’s killing. Authorities did not release the suspect’s name, and officials did not disclose a motive or whether the suspect and Killingsworth knew each other. If anyone has information about Killingsworth’s movements that morning or about the motel parking lot on May 4, please come forward.
