Tyler, TX — It was two weeks ago today that the Colorado shooter opened fire in a theater. James Holmes, shooting suspect is charged with 24 counts of murder. 

Before his alleged rampage...some experts were questioning his behavior. Psychiatrist, Dr. Lynn Fenton, at the University of Colorado treated Holmes right before the incident.The doctor warned colleagues that Holmes might be a "threat to others".

I visited East Texas Medical Center in Tyler and spoke to a Psych Therapist, Mark Taylor, about what we all need to look out for when it comes to signs of violent behavior.

There are several signs of violent behavior that are visible. One sign being a "Change of Normalcy" people change their routine often, another warning sign is “Affect” expressing different characteristics than are very different than normal.

Observing violent behavior can be challenging. When interacting with others these signs are something to think about.

You come across many people everyday and it's important to be observant.
