Tammy Duplechin Smith

Tammy Duplechin Smith, a 38-year-old Black woman from Lafayette, Louisiana, was a loving family member whose life was brutally cut short in the fall of 1997. Her final hours were spent in the company of a man who would later be identified as one of the area's most notorious serial killers, leaving her loved ones and community to grapple with a senseless loss.

On the evening of October 29, 1997, Tammy met John Peter Malveaux at the Charcoal Lounge, a local establishment in Opelousas. From the lounge, Malveaux lured her into his car and drove to a secluded, rural area in neighboring Evangeline Parish. There, he subjected her to a horrific assault, raping and strangling her to death. After killing her, Malveaux left her body in a ditch and stole her Dodge Dynasty, a vehicle that would prove to be a crucial piece of evidence leading to his capture.

The investigation into Tammy’s disappearance began after she was reported missing. A key focus for law enforcement was locating her missing car. The search came to an end on November 4, 1997, when police in Breaux Bridge discovered the stolen Dodge Dynasty in a Walmart parking lot. Inside the vehicle, they found John Peter Malveaux asleep. He was immediately arrested, and the investigation quickly connected him to a string of violent crimes that had terrorized the region.

During interrogations with investigators from both Evangeline and St. Landry parishes, Malveaux confessed to killing Tammy. He also admitted to the murders of three other women: Diane Sam, Carolyn Breaux Nichols, and Tamika Blake Wilson, all of whom had been killed earlier that year. Furthermore, he confessed to the attempted murder of a fifth woman who had survived his attack on October 19 and whose report to the police was instrumental in the investigation. His detailed confessions contained information that only the killer would know.

The legal proceedings against Malveaux moved swiftly. In November 1997, he appeared before a grand jury in St. Landry Parish and pleaded guilty to the murders of Sam, Nichols, and Wilson. In a deal to avoid the death penalty for those crimes, he accepted three life sentences without the possibility of parole. The case for Tammy’s murder was handled separately in Evangeline Parish, where the crime occurred.

Initially, Malveaux attempted to recant his confession regarding the location of Tammy's murder, claiming it happened in St. Landry Parish. However, the coroner's report confirmed that she had died in Evangeline Parish, allowing the prosecution to proceed. Because her car was stolen during the commission of the murder, Malveaux was eligible for the death penalty. After consulting with Tammy's family, who did not wish to pursue a death sentence, prosecutor Earl Taylor agreed to a plea bargain. In April 1998, John Peter Malveaux pleaded guilty to the first-degree murder of Tammy Duplechin Smith and was sentenced to a fourth consecutive life term in prison without the possibility of parole.

At his final sentencing, Malveaux expressed some remorse, stating he believed God wanted him to plead guilty but that he could not explain why he had committed the murders. His arrest and conviction brought an end to a period of fear in the community, though it could not erase the pain of the families who had lost their loved ones.

The case is considered solved. John Peter Malveaux is currently incarcerated at the Louisiana State Penitentiary in West Feliciana Parish, where he is serving his multiple life sentences. The community continues to remember Tammy Duplechin Smith and the other victims whose lives were tragically taken.
