Maryland's corrections director disclosed for the first time yesterday that the head of security at the embattled Baltimore City Detention Center failed a polygraph test aimed at weeding out corrupt members before she was fired, the Washington Post reports. Secretary of Corrections Gary Maynard made that revelation at a legislative hearing. An new audit detailed security breaches and unsanitary conditions in the Baltimore jail system, where the Black Guerilla Family gang allegedly colluded with 13 corrections officers to launder money and smuggle drugs and cellphones into the facility. Documents released yesterday through a public records request showed Gov. Martin O'Malley's office was informed two years ago that guards were probably smuggling half of all contraband into state correctional facilities and were rarely facing criminal prosecution.
