Daryl D. Keller, 36, was fatally shot on November 19, 2018, in the 200 block of Sand Street in South Peoria, Illinois. He was pronounced dead at the scene.

Peoria police conducted an extensive investigation and identified 28-year-old Lionell L. Harris as a suspect; Harris was already incarcerated in the Illinois Department of Corrections on unrelated charges when investigators named him. Authorities say they used advanced techniques, including geofencing to analyze mobile device data from the area, which contributed to identifying Harris.

In 2020 Harris was arrested and charged with first-degree murder in connection with Keller’s death. If anyone was in the South Peoria area on November 19, 2018, or has information about Keller’s movements that evening, please come forward.
