Brian Wilson killed Morrow County deputy Daniel Sherrer. Prosecutors had been seeking the death penalty in the case. However, as part of a plea agreement, they agreed to drop that possibility in exchange for Brian Wilson pleading guilty to two counts of aggravated murder and one count of murder. The charges stem from Memorial Day 2025 at Wilson’s home near Marengo, where investigators say he shot and killed Deputy Sherrer while the deputy was responding to a domestic disturbance call.
