During a press conference this afternoon broadcast live on both national and local media, Aurora police chief Daniel Oates asked journalists to please be careful in their reporting.

“A caution about social media: please, as responsible journalists, be very careful,” he said. “We are analyzing all social media that is out there about this event and I can tell you that we are already finding that there are a lot of pranks.”

Oates said shooting suspect James Holmes, 24, acted alone in the theater shooting. Holmes shot 71 people shortly after midnight at a showing of “The Dark Knight Rises.”
