They are three adult males," Christine Hill, the hospital's Media Relations Specialist, told ABC News Thursday. Police originally reported that at least two people were killed, but later would only say that "several" bodies had been found inside the business. Barbara Haynes was driving home from her teaching job when she got stuck in traffic near the scene. "I've never seen that many police vehicles on the scene and SWAT teams, uniforms, the guns...pretty heavy artillery," Haynes told ABC News. Marques Jones, 18, of Minneapolis, said he was outside a building down the street having his high school senior pictures taken when he and his photographer heard gunfire that sounded close. Minneapolis Mayor R.T. Rybak said employees who were working when the shootings occurred were together and being cared for Thursday evening.
