The Lone Star College student who went on a stabbing spree, running from building to building and taking swipes with his "razor type knife" at dozens of students planned the attack say authorities.

The 20-year-old student accused in a stabbing rampage at a Texas college campus told investigators he had fantasies of killing people and had planned the attack, sheriff's officials said late Tuesday.

Dylan Quick, 20, was charged with three counts of aggravated assault with a deadly weapon after the stabbings, said Donna Hawkins, an official with the Harris County Prosecutor's Office.

"According to the statement the suspect voluntarily gave investigators, he has had fantasies of stabbing people to death since he was in elementary school," a statement from the Harris County Sheriff's Office said. "He also indicated that he has been planning this incident for some time."

Quick used "a razor-type knife" to stab victims at the Lone Star College's CyFair campus Tuesday, the sheriff office's statement said.

Fourteen people were injured in the attack, officials said. Two of them remained hospitalized in critical condition late Tuesday, said Kathryn Klein, a spokeswoman for the Memorial Hermann Texas Trauma Institute.

Witnesses of the attack at the campus northwest of Houston described a chaotic scene. Bleeding victims collapsed to the ground. Many students and teachers ran for cover. Some sprang into action, chasing after the suspect and helping the wounded.

Of note: Lone Star College is a "gun free zone" - a designation that did very little good last January when a shooter wounded three people on campus.

No call yet to ban "razor-type knives" nor has the school yet made a determination whether they should be a "knife-free zone."

If they did, it might be interesting to see how students would be able to cut their meat in the cafeteria.
