Clinical psychologist Mara Kailin says: A mass murderer could be 'anyone'

Dr. Kailin would like to offer insight into the mind of Colorado shooter James Holmes but says "the fact of the matter is, we may never know." Kailin says, "We want to know why, we want to know what would motivate somebody to do such a horrible thing," but there are no sure bets.

The a clinical psychologist went on to say there are many ways to get answers from suspects: through different tests, interviewing and speaking with them.  Officials are still probing for a motive behind the massacre but are still unsure as to why a 24-year-old Ph.D. student would attack dozens of innocent movie-goers.
