Faculty members at his college said he got good grades. His co-workers at the local library had kind words to say about him. Neighbors remembered him as a friendly kid growing up.

When Dylan Quick, the suspect in Tuesday’s stabbing spree at Lone Star College in Texas, was arrested, it came as a shock to seemingly everybody who knew him – or thought that they knew him.

“He has shared with us that he has had fantasies about stabbing people since the age of 8,” Harris County Sheriff Adrian Garcia told reporters at a news conference on Wednesday about Quick. “He has been planning this event for some time.”

The stabbings at Lone Star, located in the Houston suburb of Cyprus, occurred Tuesday morning just after 11 a.m. Garcia said investigators believe the victims were randomly selected, and said a “razor utility knife” made by X-acto was used in the attacks.

It’s unclear what caused Quick to allegedly plan and execute the attack that led to 14 of his classmates being wounded.

"There are no signs that he was a problem student," Dr. Audre Levy, president of Lone Star College's CyFair campus, said at Wednesday's news conference. "I do know that he worked in the library, and the library staff had very fond things to say about him."

His next-door neighbor in Houston, Michael Lincoln, told The Houston Chronicle that Quick always struck him as a “very friendly kid.” But he said that he is “real quiet and keeps to himself.”

He told the paper that just last week, Quick helped him pull down a branch that had fallen on his roof. Other neighbors also described him as polite and helpful.

According to The Chronicle, Quick was born hearing-impaired, and went to a mainstream school in Houston until 2004, and then was home-schooled.

Garcia said on Wednesday that authorities hadn’t found any evidence that Quick had been bullied. He had worked in the town’s public library for a year and was just featured in his school’s “student spotlight” blog on April 1, which said Quick was also in a book club. The blog has since been taken down, but screenshots captured by KPRC.com, NBC’s affiliate in Houston, show that Quick had big plans for his future, according to the profile: to transfer to the University of Houston after getting his associate’s degree from Lone Star, and eventually pursuing a career in accounting.

Authorities apprehended Quick – a 20-year-old with curly, red-hair – shortly after the stabbings were reported from inside the health science building at the school’s CyFair campus.

The entire incident only lasted "a couple of minutes. That's how fast it happened," Garcia said.

Inside Quick’s backpack, investigators found another precision knife that wasn’t used in the attack, he said.

Investigators described Quick as matter-of-fact during their questioning.

"He has been very forthcoming," Garcia said.

Quick has been charged with three counts of aggravated assault. He was ordered to undergo a psychiatric evaluation on Wednesday. A spokesperson for the Harris County district attorney told NBC News his family had hired an attorney for him. Investigators executed a search warrant on Quick's house, confiscating his computer and other items to try to get an idea of what may have prompted him to allegedly plan the attack.

All of the victims in the attack are expected to recover.

At least 14 people were hurt Tuesday in a stabbing spree at a Texas community college apparently carried out by a student who was later taken into custody, authorities said.

At least two victims were in critical condition. It was not immediately clear how severe the other injuries were. The stabbing happened at the CyFair campus of Lone Star College, in the Houston suburb of Cypress.

Law enforcement officials have identified student Dylan Andrew Quick, 20, as the suspected assailant, and the Harris County District Attorney's Office has filed three charges of aggravated assault with a deadly weapon. 

Bond has been set at $100,000 for each charge, but more could be filed, officials said.

Quick used a "razor-type knife" in the attack, according to a statement from the Harris County Sheriff's Office. He told authorities he had fantasies of stabbing people to death since he was in elementary school, and indicated he had been planning the attack for long period of time.

The school said the attack happened “in and around” its health science building.

Memorial Hermann Texas Trauma Institute said it had two patients in critical condition and six in all, including four flown there by helicopter. Three patients were upgraded to good condition Tuesday evening and one had been discharged.

A spokeswoman for another hospital, North Cypress Medical Center, said it had taken six stabbing victims who were in stable condition.

Two other victims were treated at the scene and declined to be taken to the hospital, the sheriff said.

The school closed for the day and ordered students to find shelter somewhere safe. Campus police caught the suspect, the Harris County Sheriff’s Office said. The school will open Wednesday for regularly scheduled classes. Counselors will be on hand to speak with students and employees.

The stabbing happened just after 11 a.m., a college official said. The school had warned students that a second suspect might be at large, but sheriff’s officials said later that they believed they had the only suspect in custody.

Lone Star College student Kayla Brightkrite was walking down an empty hall on her way to class Tuesday when a teacher quickly pulled her into his classroom, she told NBC News in an email.

She initially had no idea an attack had taken place until other students quietly huddled in the room told her.

"I asked a guy what was going on and they said a kid had just been stabbed in the neck down the hall from them and they heard someone scream, 'Oh my God! Call 911!'" she recalled.

Brightkrite stayed in the classroom for nearly 45 minutes until school officials said they could exit out the back of the building.

In the parking lot, she saw a man in handcuffs being put in a police car. "He looked at me and once he got into the car, he gave me a large demented smile," Brightkrite said

In January, three people were shot at a separate campus of the same college. A federal official said that those shootings appeared to be gang-related. A 22-year-old man was charged with aggravated assault.

The Lone Star system of colleges has 90,000 students in all.
