JURY CONVICTS COVINGTON MAN: Today, a St. Tammany Parish jury found John Silas Joiner, Jr., 46, guilty on 15 counts of narcotics, weapons, flight, and resisting arrest charges. Following a four-day trial, the unanimous verdict means Joiner - a convicted felon who was on state parole at the time of these offenses - now faces a mandatory life sentence.
The conviction stems from two separate law enforcement operations in 2023 led by the St. Tammany Parish Sheriff’s Office (STPSO):
🔹 In January 2023, Joiner actively resisted arrest and fled on foot during a traffic stop. A search of his vehicle uncovered an AR-style 9mm pistol equipped with a 50-round drum magazine, brass knuckles, fentanyl, and co***ne.
🔹 In September 2023, detectives executed a search warrant at a Mandeville residence after intercepting a jail video call. The search uncovered 2,746 counterfeit blue "M30" fentanyl tablets, crystal methamphetamine, and an active clandestine laboratory pill press setup in the garage - all operating in a home where minor children lived.
Joiner's co-defendant, Amanda Flocke, testified for the state during the trial. Flocke previously pleaded guilty on May 8, 2026, and was sentenced to 30 years in the Department of Corrections.
"Today's verdict ensures that a dangerous, repeat offender will no longer be able to flood our streets with lethal poison," said District Attorney Collin Sims. "This defendant not only armed himself while trafficking high volumes of fentanyl and co***ne, but he also operated a clandestine pill press in a home where young children lived. I want to commend the St. Tammany Parish Sheriff's Office for their thorough investigations and ADAs Iain Dover and Christina Fisher for their exceptional work in securing this conviction."
The Honorable Judge Richard Swartz has scheduled Joiner's sentencing for July 8, 2026.
