MIAMI – Surveillance video obtained by The Miami Herald shows a security breach that opened jail cell doors in a maximum security wing of the Turner Guilford Knight Correctional Center in Miami on June 13.

The sliding cell doors open and two inmates walk down the hallway. One appears to hand something to an inmate in an adjacent cell.

Three inmates then confront a shirtless Kenneth Williams, who runs down the hallway of the maximum security wing. He climbs over a railing and jumps down to the floor below.

Williams lands on the floor, grabs the leg of another inmate, then hands him what appears to be a knife or blade. Corrections officers then force inmates back into their cells.

"We have some concerns for the safety of Kenneth Williams," said his attorney, J.C. Dugue.

Williams (pictured, right) fractured a vertebrae and broke his ankle, according to The Miami Herald. Dugue said he was attacked before.

"We were under the impression prior to looking at the video that it was really a malfunction. After watching the video and discussing with him (Williams) since, it seems that there may have been some error in the part of the corrections intentionally," said Dugue. "It had to have been planned. It was so coordinated and so quick. They didn't even give him a chance to react, but to jump off the second floor."

Two correctional employees said similar breaches happened at least three times in the last few months. One employee told Local 10 that correctional employees operate the computerized system.

Williams was arrested for possession of a contraband blade.

"Clearly, we will be taking that to trial also without any hesitation period. I think if you notice anything, anything he had to do was out of necessity," said Dugue.

The Miami-Dade County corrections department released a statement Tuesday, saying: "The incident which occurred in June 2013 at the Turner Guilford Knight ("TGK") facility is part of an ongoing criminal and MDCR internal investigation and pursuant to Florida State Statutes and departmental policy may not be commented on until the investigation(s) cease to be active. No information related to the incident has been officially and/or authorized to be released by MDCR and may not accurately relay the totality of events."
