'Catastrophic scene' - At least four killed in Tulsa hospital campus shooting

At least four people were killed on Wednesday in a shooting at a Tulsa medical building in a scene which police called “catastrophic”. Tulsa Police Department deputy chief Eric Dalgleish confirmed the number of dead and said the gunman also was dead, apparently from a self-inflicted gunshot wound. It was unclear what prompted the deadly assault. However, the unidentified gunman fired both a handgun and a rifle during the attack, Mr Dalgleish said.
