We’re now getting our first look at James Holmes, the alleged shooter in that horrific massacre in a Colorado movie theater early Friday.

The photo of the 24-year-old was released by the University of Colorado, where Holmes was reportedly a PhD student before withdrawing from his neuroscience studies last month.

The apartment complex where he lives is populated exclusively with University of Colorado Medical Center students, patients, and staff members — all of whom have been evacuated after it was learned Holmes’ apartment was booby-trapped with explosives.

“We are trying to determine how to disarm the flammable or explosive material,” said Aurora Police Chief Daniel Oates. “We could be here for hours or days. The pictures are fairly disturbing. It looks very sophisticated, how it’s booby-trapped. It could be a very long wait.”

In addition, 911 calls made after the shooting erupted have also been released, shedding some light on what happened, including mention of a man in a gas mask and reports of multiple victims .
