Modibo Diallo, 33, was killed on the night of February 22, 2015, at a gathering in Millcreek near 1500 East and 3350 South. An argument between Diallo and another man, identified as Ahmed Sharif-Mohamed Ali, escalated when Ali produced a handgun and shot the unarmed Diallo. As Diallo fell, Ali fired a second shot. Witnesses tried to stop Ali as he left, and a short time later someone reported a man matching his description knocking on doors nearby. Police located Ali hiding in a garage, and after a SWAT standoff he surrendered and was taken into custody.

Ali was charged with first-degree felony murder and felony discharge of a firearm. The case experienced delays over questions of Ali’s competency to stand trial; following proceedings on that issue, a jury trial went forward. In January 2025 a jury found Ahmed Sharif-Mohamed Ali guilty, and he received consecutive prison terms of 15 years to life for murder and five years to life for the firearm offense.

If anyone at that gathering or in the surrounding neighborhood remembers details about the argument, the sequence of events inside the house, or movements after the shooting, please come forward with information.
