Colorado shooting suspect James Holmes' appearance in court has sparked rumors that he is in delusion and is a disturbed person.

Homes allegedly killed twelve and injured 58 others in a shooting rampage at a midnight show of the latest batman movie, The Dark Knight Rises, in the theater in the Denver suburb of Aurora, Colo., Friday.

The alleged gunman made his first public appearance after the mass shooting in a court in Centennial, Colo., at 11:30 am EDT Monday with weird expressions that sparked anger among the victims' family and friends.

His looks described by the media as dazed, eyes drooping and deranged and motionless indicate his psychologically unbalanced personality.

Holmes appeared in a maroon jailhouse jumpsuit and had a dazed look on him throughout the procedure, speculating theories that he was on medication or illegal drugs.

Experts who have observed the suspect believe that he may be delusional. They have said that it is difficult to know the real motive behind Holmes alleged attack unless he himself reveals it, which they feel is unlikely.

However, the statement he reportedly made to the police saying he was the Joker(a villain in the Batman movies) and his appearance resembling a fighter with bullet proof vest, riot helmet and gas mask during the attack point to an illusionary state of mind. He reportedly had arms and ammunition in his flat and his voice mail box status message was weird, according to media reports.

Though there were no reports of violence by him in the past, experts believe that there are indications that Holmes is a person withdrawn to himself. Such persons' behavior doesn't reveal their violence trait always.

This is not a person that gets in bar fights and hurts other people. They're more likely to make statements about how they're going to get people. Those people are going to see they'll know who he is, and they'll be sorry, Dr Stevan Hobfoll, a professor of behavioral sciences at Rush University Medical Center in Chicago, was reported as saying by ABC News.

Deranged expressions of Holmes with red-orange dyed hair were also giving a feeling that he was disconnected from what was happening around him. Though some psychologists believe it is unfair to link his loner character with violence, others feel that social inclination towards loneliness can lead to violence.

William Bukowski, a professor of psychology at Concordia University's Center for Research in Human Development, Montreal, said in an interview Monday that if Holmes was a loner, the more pertinent question would be: What message did he internalize from his status as a loner? When a loner starts to dehumanize others, has no compunction about doing harm to others, and develops a fantasy persona for themselves, that's when things can unravel.

Psychologists also point to a possibility that Holmes might have created an illusionary world for himself and acted on his delusions.

The thing to realize is that within his own thoughts, what he was doing was completely logical. To him, he was accomplishing something worth doing, said Dr. E. Fuller Torrey, founder of the Treatment Advocacy Center in Arlington, Va.

Investigators have disclosed that he is refusing to cooperate and is not willing to talk to them. Holmes will be formally charged July 30.
