" (The suspect) goes by the name Kevin Dahlgren on social networks, lives in California and speaks only English," the police website said. The victims were a family but Vedrova declined to give any further details. The man, who police believe is 20-years-old, is the only suspect. Reporting by Jason Hovet; Editing by Angus MacSwan
