(FOX40.COM) -- A lawsuit has been filed against the California Department of Corrections and Rehabilitation after a hyper-violent prisoner allegedly captured a female officer in a prison facility for several hours and subjected her to severe physical and emotional trauma, including sexual assault. The incident happened at the CDCR Sierra Conservation Center in Jamestown after a long series of "inexcusable and negligent decisions by the CDCR," according to the lawsuit. The inmate, Robert Lawrence Ransom Jr., was considered a dangerous individual who had been incarcerated for multiple hyper-violent murders. Attempted murder suspect tries breaking into Sutter County home, residents inside CDCR reportedly transferred Ransom to a lower-security facility which was designated as a training center for firefighting techniques in a rural part of California. The lawsuit alleges that the CDCR failed to provide any training, information, or intelligence regarding the status of this violent inmate. The plaintiff, Katie Jackson, said she was unaware of his violent status. “The CDCR placed this woman in a situation where she was repeatedly and brutally violated, and her life was put in jeopardy,” said attorney Paul Goyette of Goyette, Ruano & Thompson. “The extent of injuries, horrific, physical and mental torture she endured, and continues to relive on a daily basis is sickening." Man sentenced to at least 50 years in prison in string of Sacramento-area bank robberies Goyette added, "As much as this incident was a grotesque and nightmarish display by an individual void of any humanity, CDCR created the conditions to make this incident possible and created the conditions that allowed the incident to last over a protracted period of time, causing maximal damage to the victim officer. This civil suit is the first step toward holding CDCR accountable.” The lawsuit claims that Ransom concealed clothing that resembled a custodial officer’s uniform, got inside a control booth, gained access to at least one loaded assault rifle, and used it to kidnap, corner, and brutally assault the female officer for about four hours. "Even more dreadful, other on-duty CDCR officers conducted multiple ongoing cell checks throughout these four hours, verifying the prisoner was within his cell, when he was in an entirely different location of the facility, carrying on his extensive and deplorable acts," Goyette said. "Adding to these horrific acts, a sergeant on duty later claimed he was 'too busy' as the reason for being unable to perform his duties of checking the location properly."
