ALEXANDRIA, LA—United States Attorney Stephanie A. Finley announced today that two prisoners at the U.S. Penitentiary in Pollock, La., pleaded guilty to beating a fellow inmate resulting in traumatic brain injury.

Jeffrey Lovell, 32, and Christopher Simpson, 36, pleaded guilty before U.S. District Judge Dee D. Drell to one count of assault resulting in serious bodily injury. According to evidence presented at the guilty plea, video cameras captured Lovell and Simpson assaulting a third inmate outside of his cell on June 11, 2013 at the U.S. Penitentiary in Pollock. The inmate was struck around his head and torso repeatedly. The prisoner was later brought to a hospital where he was treated for traumatic brain injury, which required a feeding tube.

The defendants face up to 10 years in prison, three years of supervised release, and a $250,000 fine. A sentencing date of February 13, 2015 was set.

The FBI and the U.S. Bureau of Prisons conducted the investigation. Assistant U.S. Attorney Seth D. Reeg prosecuted the case.
