More than 250 Maryland corrections employees have been arrested since 2013 on charges including assault, looting, driving under the influence and having sexual relations with inmates, state officials said Thursday.

The employees worked in facilities across the state, “from Cumberland to the lower shore,” Robert Thomas, of the Department of Public Safety and Correctional Services, said in a letter.

Corrections Secretary Stephen T. Moyer told a state panel on Wednesday that 253 employees had been arrested, out of a total workforce of 11,000, and that about 200 of them remain on the job. The bureau provided some additional information on Thursday but would not elaborate further because many of the cases remain under investigation or in the disciplinary process.

Moyer said the statistics show the need for the corrections bureau — which he took over in February — to do a better job vetting the people it hires and firing those who get into trouble with the law.

“If people are assaulting people, or people are getting arrested for DWI, people are committing theft — I don’t want them working here,” Moyer said Thursday.

Until last year, state law gave the corrections bureau 90 days to complete disciplinary cases once officials became aware of criminal charges against uniformed employees. But officials say the process often took as long as six months.

Then-Gov. Martin O’Malley (D) signed legislation last year that eliminated the 90-day processing window for criminal cases and for incidents involving inmates or events at correctional facilities.

Moyer said he is streamlining the process to resolve delays and ensure that his office is quickly aware of offenses. He has hired a new investigations director, human resources director and other top officials to help lead the process.

“All are working with a specific mission in mind: To make certain that we hire good people faster and terminate law breakers and bad employees faster,” Thomas said, adding that the department has already reduced the time it takes to process termination cases to about 45 days.

The employees arrested over the past 32 months include two female corrections officers who were seen on surveillance video looting a 7-Eleven during April’s riots in Baltimore. Both were charged with felonies, and the department has placed them on emergency suspension. Their hearings and court cases are pending.

The employees Moyer cited Wednesday do not include two dozen who were indicted in a notorious 2013 case at the recently shuttered Baltimore men’s detention center where corrections officers helped a gang leader operate a violent drug enterprise.

AFSCME, the union that represents the state’s corrections officers, noted that only a tiny fraction of the 11,000 personnel who work for the department are facing charges. But the union agreed that the agency needs to root out bad actors.

“If these folks committed serious crimes and they’re convicted, we agree — they should lose their jobs,” said Jeff Pittman, a spokesman for AFSCME. “But the vast majority of the employees are doing their jobs with integrity.”

As part of his effort to improve hiring and firing, Moyer has proposed cutting 63 human-resources positions and consolidating separate staffs at each prison facility into one office.

Union officials say the proposal is making scapegoats of innocent workers. Pittman said “many state workers with sterling job records and no responsibility for hiring and firing are being unfairly targeted for firing themselves.”

The state Board of Public Works on Wednesday delayed a decision on cutting those positions until mid-September. The board is chaired by Gov. Larry Hogan (R).
