MEMPHIS – Mervin Anderson, a 40-year-old man from Memphis, was convicted on September 30, 2025, for possessing homemade knives while in a federal prison. The illegal items, known as “shanks,” were two homemade metal knives found in Anderson’s possession. He was found guilty of one count of possession of contraband in prison.
Video surveillance played a crucial role in the prosecution, showing Anderson confronting another inmate and swinging the shanks at him. A corrections officer intervened during this incident, which led to the discovery of the weapons. When the knives were extracted from Anderson, he made a statement claiming he was ready to harm the other inmate, indicating a serious threat to the prison environment.
Following this conviction, Anderson is facing a maximum sentence of five years in prison. The specific sentencing date will be determined later. At the time of this incident, he was already in custody awaiting trial for another serious offense: conspiracy to distribute fentanyl, with this trial slated for November 3, 2024.
The investigation into Anderson’s possession of contraband is being conducted by the U.S. Marshals Service and the Shelby County Division of Corrections. This incident raises concerns over security within federal detention centers and the challenges of preventing contraband from entering correctional facilities.
This conviction and the accompanying possession of homemade weapons situate the case in a broader context of issues regarding inmate safety and the rules governing prison conduct as authorities continually strive to maintain order within jail facilities.

The issue of inmate violence and contraband is primarily addressed through surveillance and strict regulations, with ongoing efforts by correctional facilities and law enforcement to prevent dangerous situations from occurring. Cases like Andersonโs underscore the vigilance needed to ensure the safety of inmates and correctional officers alike.

Possession
Individuals found guilty of possessing contraband, especially weapons in a prison setting, face severe penalties that may include substantial prison time.
