A member of the Bloods street gang who operated in Howard County was sentenced on Monday to 16 years in prison for racketeering and using a gun during a crime. Kenneth Ragan-Armstrong, 23, of Savage and Laurel, had pleaded guilty in U.S. District Court in Baltimore. According to his plea agreement, Ragan-Armstrong in 2010 founded “Cut Throat Committee,” a gang composed mostly of members who attended high school together. Ragan-Armstrong admitted that he committed at least two armed robberies and a burglary in which he pistol-whipped the victim on the head and also sold drugs. Ten other defendants have pleaded guilty to the racketeering conspiracy, which was investigated by the federal Bureau of Alcohol, Tobacco, Firearms and Explosives and the Howard County Police Department.
