They said that he might've bought a ticket and entered the theater as a normal customer. Then he propped open the door, which was an exit door with no alarm, and left to change into his gear in his nearby car. Then he re-entered and started with the tear gas and shootings. Thanks for your concern, I'm just grateful it wasn't me or my husband there. They haven't released the names of all the 12 people killed, so I don't know if there's anyone I know, but there are also many injured and a few in critical condition. We had the Columbine school shooting nearby a few years back, people are going crazy. I wonder if this kid was on any anti-depressant drugs, that doesn't help.
