The AR-15-style rifle used to kill two victims in the mass shooting at a St Louis high school was the very same firearm that was taken away from gunman Orlando Harris just days earlier, it has been revealed.
St Louis police confirmed on Wednesday night that the 19-year-old mass shooter – who was known to have mental health issues and whose mother feared he should not have a firearm – somehow got the gun back and used it to go on a shooting rampage in his former high school.
