SAN DIEGO -- The California family of the suspect in a mass shooting at a Colorado movie theater says their hearts go out to those involved.

Police in San Diego read a statement Friday morning from family members of 24-year-old James Holmes, who graduated from high school in the San Diego area.

The family asked the media to respect their privacy. They say they're cooperating with authorities in San Diego and Aurora, Colo., and are trying to process everything.

Police released a written statement from Holmes' family: "Our hearts go out to those who were involved in this tragedy and to the families and friends of those involved."

San Diego police spokeswoman Andra Brown says there's nothing to suggest the family had any involvement.

A spokeswoman for the University of Colorado School of Medicine in Denver says Holmes was a student there until last month but didn't know why he withdrew.
