Four inmates escaped from the Harrison County jail early this morning, and two are back in custody. Harrison County sheriff Melvin Brisolera says they are considered dangerous, and the search is continuing. A perimeter has been set up around the jail and several police agencies, as well as helicopters are involved in the search for the two missing inmates. At this time, it's not know how the inmates escaped, or if there were any accomplices working on the outside. Details of the capture of the two inmates have not been released yet. WLOX News has a crew on the scene, and will have more on the story later tonight.
