Incident
Deputy William Dillemuth was shot and killed by ambush while attempting to serve a warrant at 5011 Kraus Road in Clarence. The suspect had failed to appear in court for narcotics possession.

The deputy was able to flee back to his patrol vehicle and call for assistance. When responding officers arrived, they were unable to get to Deputy Dillemuth due to the barrage of gunfire from the suspect for over 30 minutes. Deputy Dillemuth was transported to Millard Fillmore Suburban Hospital, where he died at 3:15 p.m. The other deputy was shot in the abdomen but survived his wounds. The suspect barricaded himself in the house for over nine hours. He was convicted of Deputy Dillemuth's murder and sentenced to life in prison. He will be eligible for parole in 2039.
