Colo. shooting suspect's family says "hearts go out" to those involved

(CBS/AP) The Colorado shooting suspect's family in California said their hearts go out to those affected by the movie theater massacre.

"Our hearts go out to those who were involved in this tragedy and to the families and friends of those involved," the family of James Egan Holmes said in a statement released by San Diego police.

Holmes, 24, is being held by police after opening fire at a Aurora, Colo., movie theater where "The Dark Knight Rises" was playing during a midnight screening Friday. At least 12 people have been killed and dozens more were wounded.

Police said the suspect's family is cooperating with authorities in Colorado and California. San Diego police spokeswoman Andra Brown said there's nothing to suggest the family had any involvement.

"We are still trying to process this information and we appreciate that people will respect our privacy," the statement continued.

The shooter was arrested shortly after the attack near a car outside the multiplex theater.

Holmes doesn't have a criminal record in Colorado or San Diego, where he graduated high school and where his parents currently live. Pentagon officials said there are no records of Holmes serving in the military.

Officials at the University of Colorado School of Medicine in Denver confirmed that Holmes was "in the process of withdrawing" from their graduate program in neurosciences.

A law enforcement official told CBS News that Holmes appears to be the lone gunman.  Police evacuated the area around Holmes' Denver-area apartment, saying it was apparently booby-trapped and full of explosives.

Authorities did not release a motive. The FBI said there was no indication the shooting was tied to any terrorist groups.
