Karl Granzow sentenced to 18 months

Former Prince George's County Executive Jack Johnson appears outside the Greenbelt courthouse in advance of his sentencing.

A former Prince George’s County fire official who pleaded guilty to extortion and tax evasion was sentenced to 18 months in prison Wednesday.

Prosecutors say 47-year-old Karl Granzow was part of the same corruption scheme that led to the arrest of former county executive Jack Johnson.

Granzow admitted to partnering with county developers to bribe public officials for development favors related to the Greenbelt Station development project.
