A legislative inquiry into Maryland’s prison system is broadening to include a coordinated effort between the Senate and House of Delegates.

Plans are in the works, State House aides confirmed Thursday, for a joint hearing in the aftermath of a federal indictment that accused 13 guards at a Baltimore jail of colluding with a prison gang that authorities said had essentially taken over the institution.

The House Judiciary Committee has announced a hearing for Wednesday on the “corruption” at the Baltimore City Detention Center. But that meeting could now be put off, given emerging plans for the House and Senate to work together.

Gov. Martin O’Malley (D), meanwhile, met Thursday with House Speaker Michael E. Busch (D-Anne Arundel) and Senate President Thomas V. Mike Miller Jr. (D-Calvert) to brief them on the scandal at the Baltimore City Detention Center, a state-run institution.

“It was an opportunity for the governor to bring them up to speed and make sure they have the information they need,” said O’Malley spokesman Raquel Guillory.

O’Malley this week voiced full confidence in the head of Maryland’s prison system and argued that the federal indictments of 25 inmates and guards at the Baltimore jail last week was “a very positive development” in rooting out corruption.

According to the indictment, officers smuggled in cellphones and drugs for members of the Black Guerilla Family gang and even had sex with them. Four officers became pregnant as a result of trysts with one detainee, prosecutors said.
