What we know:

Nathan Douglas Davin, 47, was sentenced Thursday to 261 months in prison for second-degree murder with intent but not premeditation in St. Louis County Court. Davin’s sentence falls within the guideline range set by Minnesota law.

Davin pleaded guilty on June 8, 2026, admitting that he shot and killed his elderly mother in their Ninth Avenue East residence on Aug. 16, 2025. Officers found Davin at the scene with blood on his hands, and his mother deceased in a recliner from a gunshot wound to her face. The firearm was found in Davin’s bedroom.

After initially denying responsibility, Davin later admitted to the killing while alone in an interview room at police headquarters. He began serving his anticipated sentence following his guilty plea, pending the sentencing hearing.
