Louis Henry Wagner II was a 25-year-old sergeant with the St. Tammany Parish Sheriff’s Office who was shot and killed on June 3, 1978, in St. Tammany Parish, Louisiana. Investigators described the killing as an ambush: Wagner had been driving home from the sheriff’s office when he was shot, his body later found in front of a business on Louisiana Highway 21 south of Covington, while his pickup was discovered hours later at a different location. The shooting appeared targeted, and later accounts tied the motive to retaliation for an arrest Wagner had made.

The case became associated with Robert Lee Willie, who confessed to participating in the killing while on death row for a separate murder. He implicated three other men — Richard A. Lott, Perry O. Phillips Jr., and Bobby K. Raney — but later recanted that part of his statement and the charges against those three were dropped. Willie pleaded guilty to second-degree murder in Wagner’s death and received a life sentence. Confessions by Henry Lee Lucas and Ottis Toole were later considered and then rejected as unreliable, and a grand jury declined to indict them.

Does anyone have information about Wagner’s final movements that night or the pickup truck’s last known locations?
