Harris County Sheriff Adrian Garcia said a 911 call was received at its call center at 11:12 a.m. regarding a stabbing at Lone Star College, 9191 Barker Cypress Road. "The call was described as a white male, on the loose, stabbing people," said Garcia.
Tuesday evening, Harris County District Attorney's office charged Dylan Andrew Quick with three charges of aggravated assault. The charges against Quick carry a $100,000 bond each.
College officials said the incident happened in and around the LSC-CyFair Health Science Center.
"What we know at this point is that 14 people were injured. Two of them refused treatment," said Garcia at an afternoon press conference on the school's campus.
An update from the Lone Star College system confirmed that six victims were taken to Memorial Hermann Hospital and six to North Cypress Medical Center. Four of the victims were airlifted and eight transported via ambulance, according to the update.
Garcia stated that two of the victims were in critical condition and four were in fair condition. Garcia would not confirm earlier reports that many of the victims were stabbed in their cheeks, shoulders and/or necks.
"This is a current and ongoing investigation," he told media at the news conference.
The Harris County Sheriff's Office said the instrument used by Quick to stab and cut the victims was a razor-type knife. There were pieces of blade in at least one victim, according to HCSO, broken blade pieces in the area where the cutting occurred, and the handle to a razor-type knife was found in a backpack that Quick was carrying when he was arrested.
According to the statement Quick voluntarily gave investigators, he has had "fantasies of stabbing people to death" since he was in elementary school. Authorities said Quick also indicated that he has been planning this incident for some time.
Xiony, a student at the college, said she was sitting in a chair in a hallway and studying for a class when she was attacked.
"I thought he was poking me and then I felt this sharp pain," said Xiony. "Then I realized he was actually stabbing me with something. I immediately pushed him away and he just walked off like nothing. I've never seen him before."
Xiony suffered wounds to her chin, neck and hand.
"I could feel the blood coming down my neck, which got me really scared because I thought he hit a big artery," Xiony said.
Student Michelle Alvarez said the man tried to stab her and grazed her neck, but she pushed him away and ran.
"When I heard people behind me, I was like, no, I have to go run into a room and get safety," Alvarez said.
College officials have not said if the victims were students, staff or both. Deputies said the victims appeared to be randomly targeted.
Deputies previously were searching for a second suspect, but Lone Star College System surveillance video and eyewitness accounts confirmed that there was only one suspect in the incident, according to officials at the college.
Investigators said a student tackled the suspect and that helped them capture the man. Garcia, however, would not comment on the details of the possibility of a student subduing the suspect.
Quick (pictured, right) was recently featured on the college's website because of his longtime participation in library activities. The student spotlight indicated that Quick was born deaf and at the age of 7 he received a cochlear implant.
The college's business office said the Cy-Fair campus was locked down and then evacuated. Cars were being searched as people left the campus. School officials said that Lone Star College would be closed for the remainder of the day Tuesday, but would resume normal operations on Wednesday.
Some students said they are worried about their safety.
"I'm hoping they do something about it," student Michael Chalfan said. "More security or something like that because with us college students, we feel like we're vulnerable."
