Kcoree Warren, 44, was shot and killed at his Ferguson, Missouri, home on July 8, 2025. Warren served as a key witness in that case.

On May 29, Lavonda Harmon allegedly visited Warren’s home and offered him $12,000 to drop the charges; Warren refused. Around 2 months later, an associate of the Harmon family identified as Andrew Klaus came to Warren’s Bayview Drive residence and fatally shot him through the front door. Neighbors heard the shots and saw Warren’s children crying outside.

Hours after Warren’s death, Klaus was found murdered in St. Louis and a white Kia seen leaving Warren’s scene was found burned nearby. A multi-agency probe, including the FBI, is investigating possible links between the crimes.

If anyone has information about Warren, the visit by Lavonda Harmon on May 29, or the white Kia seen near Bayview Drive, please come forward.
