Video footage that appears to have been recorded by an inmate unveils some horrific conditions inside of the Mississippi Prison System, where five inmates have been brutally killed and at least two have escaped following extreme rioting.

As of today(January 6), the video, which appeared on Twitter, has been retweeted over 6K times.

The footage was captured at Mississippi State Penitentiary at Parchman, where two inmates were stabbed to death and two others made a dynamic escape during the rioting. One of the escapees has since been captured.

As the orange and white-striped dressed inmates walk through the muddy hallways of the prison, they are making claims on video of widespread mildew and mold to living without electricity, working plumbing, heat and sleeping accommodations.

The Mississippi Department of Correction released a statement on Friday about the rioting, which began on Dec. 29.

“Four inmates have died and several have been injured at two state prisons and one regional during major disturbances since Sunday. One death occurred at the South Mississippi Correctional Institution, (SMCI) in Leakesville, two at the Mississippi State Penitentiary (MSP) at Parchman, and one at the Chickasaw County Regional Correctional Facility (CCRF) in Houston, Miss.. MDOC investigators have determined a fifth death and a minor fire, both at MSP, are unrelated to the major disturbances.”

This is far from the first time the MDOC has been under fire. A 2012 prison riot at the Adams County Correctional Facility left a guard dead and former MDOC Commissioner Chris Epps was arrested for bribery, money laundering and wire fraud charges involving potentially hundreds of millions of taxpayers’ dollars in 2014.
