Following the death of 49-year-old Wilbert Lucero at California State Prison in Lancaster, three inmates have been placed in restrictive housing. The incident occurred during a security check on February 3rd. Lucero, serving a life sentence for attempted first-degree murder, was found unresponsive in his cell and pronounced dead shortly after.

Jeremy Rakisits, Lucero's cellmate, along with Ismael Marquez and Raymond Moreno, are under investigation by the prison's Investigative Services Unit and the L.A. County District Attorney’s Office. Rakisits is serving a life sentence for second-degree murder. Marquez and Moreno are also serving life sentences for first-degree murder charges.

Authorities have not released details on the cause of death or if any weapons were found. The prison, which opened in 1993, houses approximately 3,000 inmates. The investigation is ongoing, and further details will likely emerge. These circumstances may lead to heightened scrutiny of prison safety protocols.

This incident underscores the inherent risks within correctional facilities and the critical need for rigorous safety measures. The potential for violence and the complexities of investigations within these settings often present unique challenges. Updates on the investigation's progress will be closely watched.
