Former P.G. deputy fire chief sentenced to 18 months

A former high-ranking Prince George’s County fire official was sentenced Wednesday to 18 months in prison for his role in wide-ranging schemes involving local developers and elected officials.

Karl Granzow, 47, who retired from the Prince George’s County Fire and EMS Department as a deputy chief in 2009, pleaded guilty last year to conspiring to commit extortion and falsify Federal Elections Commission records, as well as income tax evasion.
