ANNAPOLIS, Md. — The attorney for the Maryland man accused of at least nine random shooting incidents said he is exploring a not criminally responsible plea.

William Davis, Anne Arundel County public defender, said Monday there were some “substantial mental health issues” at the time of the incidents.

Davis would not elaborate on the details of the mental health of 35-year-old Hong Young.

Young, a Prince George’s County resident, was arrested in early March and charged with attempted murder and assault in a Feb. 24 shooting that injured a man. Court documents show that Young told police that he heard voices telling him to shoot at a random driver.

Police have linked Young to eight other shootings in central Maryland, including one at the National Security Agency.
