Maryland State Police superintendent Sheridan retiring

ANNAPOLIS — Maryland State Police Superintendent Terrence Sheridan is retiring.

Gov. Martin O’Malley made the announcement Friday. The governor says Marcus Brown, who is currently the chief of the Maryland Transportation Authority Police, will replace Sheridan on Aug. 1 to lead an agency with more than 2,500 employees.

Sheridan is retiring after 46 years of law enforcement experience. He was the chief of the Baltimore County Police Department for more than 11 years.

Brown has been the MDTA chief since 2007. He previously worked as the deputy commissioner of operations for the Baltimore Police Department, where he was responsible for more than 3,000 officers and all operational units.
