Cypress, Texas: A student who told police he’d fantasised for years about stabbing people to death was charged Tuesday with carrying out a building-to-building attack at a Texas community college that wounded at least 14 people, many of whom were stabbed in the face and neck, authorities said.

The Harris County Sheriff’s Office said in a statement that 20-year-old Dylan Quick used a razor-type knife, and that he told investigators he’d been planning the attack at the Lone Star College System’s campus in Cypress, a Houston suburb, for some time. Two people remained in critical condition late Tuesday at Memorial Hermann Texas Trauma Institute, hospital spokeswoman Alex Rodriguez said.

Pieces of the blade were found in at least one victim, according to the sheriff’s office. Broken blade pieces also were found in the area where the stabbing occurred, and the handle was discovered in a backpack that Quick was carrying when he was arrested.

Quick was charged Tuesday night with three counts of aggravated assault. It wasn’t immediately clear if additional charges would be filed, though he is scheduled to make his first court appearance Thursday.

Authorities were seen entering Quick’s parents’ home in a middle-class neighbourhood of Houston on Tuesday night. No one answered the door or the phone at the red brick home, where two vehicles were parked in the driveway, including a Honda Accord with a licence plate that said “DYLAN.” It was not immediately known if Quick had a lawyer.

“I can’t imagine what would have happened to that young man to make him do something like this. He is very normal,” said Magdalena Lopez, 48, who has lived across the street from the Quick family for 15 years.

Quick, she said, would always say hello to her and her family when she would see him outside taking out the trash or working on his family’s front lawn. Quick is deaf, she said, and a street sign, “Deaf Child In Area,” was posted on the block of brick, ranch-style homes warning drivers of his condition.

“I can’t believe he would do it,” Lopez said.

The stabbing spree began around 11.20am Tuesday and sent at least 12 people to hospitals, while several others refused treatment at the scene, according to Cy-Fair Volunteer Fire Department spokesman Robert Rasa.

Diante Cotton, 20, said he was sitting in a cafeteria with some friends when a girl clutching her neck walked in, yelling: “He’s stabbing people! He’s stabbing people!”

Cotton said he could not see the girl’s injuries, but when he and his friends went outside, they saw a half-dozen people with injuries to their faces and necks being loaded into ambulances and medical helicopters.

Michelle Alvarez told the Houston Chronicle that she saw the attacker running towards other students and tried to back away. She said she didn’t even feel it as he swiped at her.

“He came running and swinging at my neck, as I tried to get out of the way,” she said.

Harris County Sherriff Adrian Garcia said that when emergency calls came into the department, there were indications that “students or faculty were actively responding to work to subdue this individual.”

“So we’re proud of those folks, but we’re glad no one else is injured any more severely than they are,” Garcia said.

Media and police swarmed the quiet neighbourhood where the Quick family lives about 16km from the campus after the attack. Some neighbours described him as quiet, and noted that he didn’t appear to have many friends, staying indoors most of the time unless his parents were outside working in the yard.

Michael Lincoln, who lives next door to the Quick family, described the suspect as friendly.

“If he’s outside, he speaks to me, ‘Hey neighbour, how you doing?’” Lincoln said.

He added that Quick had never been aggressive, which makes the accusations against him shocking.

“He stayed inside most of the time unless they were doing yard work,” he said.

The attack came three months after a different Lone Star campus was the site of a shooting in which two people were hurt. The suspected gunman in that incident is charged with aggravated assault.
