A former Washington College student who called police Tuesday evening threatening to commit mass violence on campus was arrested hours later at his Cecil County home after a multi-agency response that placed the college on lockdown. Kent County News reports Grafton Steele Howard, 25, of Chesapeake City, called Chestertown Police around 7 p.m. Jan. 20 and asked what would happen if he went onto the Washington College campus and shot members of the school’s administration and public safety officers, according to Chestertown Police Chief Ron Dixon. “The caller provided detailed and specific information that led to the threat being deemed credible,” Dixon said.
