The Aurora Theater Shootings: Five Years Ago

On July 20, 2012, James Holmes opened fire during a screening of "The Dark Knight Rises," killing 12 people and injuring more than 70.

An ambulance is parked outside the Century 16 Theater in Aurora, Colorado, early on July 20, 2012, after a gunman opened fire at the premier of "The Dark Knight Rises."

About 10 minutes into the movie, James Holmes entered through an emergency exit, throwing a tear gas canister inside the packed theater and opening fire on the crowd with a rifle and then a shotgun after that weapon jammed.
