"Our hearts are broken" said Colorado governor John Hickenlooper Friday after a mass shooting at a theater in Aurora.
Twelve people died, another 59 people were injured when a gunman opened fire during the midnight showing of "The Dark Knight Rises."
A suspect was arrested outside the theater by a vehicle parked behind the theater.
"This is the act of an apparently very deranged man," said Hickenlooper.
The governor said Colorado is a state that has always come together and we will come back stronger than ever.
"This was an absolute horror for all of those people that were in those theaters and their families," said Aurora Mayor Steve Hogan.
Hogan said parents should talk to their children about the shooting.
"Its tragic, its horrible, but its isolated," said Hogan.
