The gunman who killed a teacher and a 15-year-old girl in a deadly school shooting in the US city of St Louis, Missouri, was heavily armed and equipped with hundreds of rounds of ammunition, police say.
Police Commissioner Michael Sack said on Tuesday that the gunman, 19-year-old former student Orlando Harris, had an AR-15-style, semi-automatic rifle and more than 600 rounds of ammunition during Monday’s attack. Harris was killed in an exchange of fire with police.
