Adam C. Gaubert, a 47-year-old master trooper with the Louisiana State Police, was killed on October 9, 2021 while on duty. Investigators pieced together a violent, multi-parish shooting spree that began in Livingston Parish, where the suspect shot two people and stole a vehicle, then moved through the Baton Rouge area. In Ascension Parish, Gaubert was ambushed while seated in his marked patrol unit; he was discovered more than 12 hours after being killed, a delay tied to emergency radio protocols used during the manhunt.

Authorities said the suspect, Matthew Mire, later killed Pamela Adair, wounded another person, and exchanged gunfire with a pursuing trooper before fleeing into woods. Warrants were obtained in multiple parishes, including first-degree murder of a police officer in Ascension Parish and related charges in East Baton Rouge Parish. The case left two people dead and others critically injured, with Gaubert’s killing central to the prosecution’s case.
