On the afternoon of Sunday, October 12, 2014, 37-year-old Christopher Mansaw was shot and killed while standing outside a residence in the 3000 block of College Avenue in Kansas City, Missouri. Around 1:30 p.m., several males approached; one produced a firearm and fired, and the group fled. Mansaw’s children, who were present, flagged down police and said their father had been shot. Mansaw was taken to a hospital and later pronounced dead.

Investigators tied the shooting to an earlier confrontation at a nearby convenience store, where Mansaw’s children reported being accosted by four males; one acted aggressively and tried to push a witness out of the store before the group left and then returned to the College Avenue address. Police identified 32-year-old Dewayne D. Toombs as the primary suspect and prosecutors charged him in November 2014 with second-degree murder and armed criminal action; the murder count was later upgraded to first-degree murder. Toombs pleaded not guilty and went to trial in early 2016; on February 19, 2016, a Jackson County jury found him not guilty of first-degree murder and the armed criminal action charge. No one else has been convicted in Mansaw’s killing.

Are there witnesses or information about the group that approached the store and the house who haven’t come forward?
