Police said the suspect used an "AK-47-type weapon", which was initially reported to be an SKS.[10] However, later reports indicated that the weapon was a WASR-10 semi-automatic rifle legally bought in Nevada on July 9.[2][11][12] Police at the scene, who reportedly engaged the shooter within a minute of the start of the shooting, quickly killed the gunman.[13] The police chief credited the fast response to a heavy police presence with "many, many officers in the park".[6]
