The suspected shooter in that Colorado movie massacre, James Holmes, will face a judge Monday morning.
Holmes is accused of opening fire at a midnight showing of "The Dark Knight Rises" at a theater in Aurora. Twelve people were killed.
On Sunday night, thousands gathered in Aurora to honor and pray for those killed in Friday's shooting.
Police say Holmes has not been cooperating with them in their investigation.
A law enforcement source says police found a Batman poster and mask inside his apartment.
Meanwhile, President Barack Obama landed in Colorado on Sunday to comfort survivors and the victims' families. He met with family members at the University of Colorado Hospital, which treated 23 of the people injured.
Ten remain there, seven hurt critically.
This was the president's second visit to Colorado in less than a month to comfort residents. Late last month, he flew to Colorado Springs, where hundreds of homes were destroyed in a wildfire.
Mitt Romney said Obama's decision to meet with the families of the victims was "the right thing."
The Republican candidate put politicking aside while speaking at a fundraiser in San Francisco on Sunday night.
After a moment of silence, Romney told donors he's been thinking about the senseless killing in Colorado.
