Fourteen people are dead after a gunman opened fire during a midnight screening of "The Dark Knight Rises" early Friday morning.
At least 50 people are injured, according to the Los Angeles Times. The mass killing took place in a mall in Aurora, Colo., a suburb of Denver.
At a news conference, Aurora Police Chief Dan Oates told reporters that a suspect is in custody.
In a statement, President Barack Obama condemned the shooting, calling on Americans to keep the citizens of Aurora in their thoughts and prayers. He said federal and local law enforcement agents were still responding, and said his administration would work with authorities in the wake of the murders.
"Michelle and I are shocked and saddened by the horrific and tragic shooting in Colorado," President Obama said.
Adding, "We are committed to bringing whoever was responsible to justice, ensuring the safety of our people, and caring for those who have been wounded. As we do when confronted by moments of darkness and challenge, we must now come together as one American family. All of us must have the people of Aurora in our thoughts and prayers as they confront the loss of family, friends, and neighbors, and we must stand together with them in the challenging hours and days to come."
