King, who has spent more than 30 years in law enforcement, was director of the police academy in Hagerstown, Md., and before that was police chief in Gaithersburg, Md. Gregory also cited family issues when he resigned after two years. He took over for former Police Chief Rick Gregory in November 2013. Gregory replaced Dave Bolda in 2011, who served as interim chief for six months. Before that, Craig Geslison retired just as an external investigation began into his department after accusations of misconduct involving three ex-officers.
