(KMOV) -- Two teenage prisoners are back in custody after escaping from a medium security facility in St. Louis.
Police say Eric Gray and Kurt Wallace, both 17, were found around 5:45 p.m. hiding in a vacant house in the 5900 block of Wabada. They were taken into custody without incident.
Authorities say the two escaped sometime between 1:45 a.m. and 4:00 a.m. on Wednesday from the Medium Security Institution, also known as the Workhouse, in the 7600 block of Hall St.
Gray was in jail awaiting trial for a June 2009 murder. Wallace was awaiting trial for a first-degree assault charge from October 2008. Both suspects were certified to stand trial as adults.
The jail's commissioner said most murder suspects are transferred to the higher security justice center once they turn 17. In this case, Eric Gray's attorney requested and a judge ordered Grey to remain at the lower security jail until trial.
At a news conference Wednesday morning, Gene Stubblefield, the Director of the Division of Corrections, called the incident a "gross breach of security."
Stubblefield says that the two teens were being held in a separate cell because they had been acting up.
According to Stubblefield, the teens purposely flooded their cell, were ordered to clean it up and were reportedly never checked on again.
The teens then walked out through a door in a lobby, scaled a fence with barbed wire on top and then crawled under two fences to escape. Stubblefield says that there is evidence that the teens were injured while climbing the barbed wire fence.
Stubblefield says that security protocol was not properly followed in this case. He says that there was a delay in notifying police and he is looking into it.
