Just outside the south entrance of campus, Harris County Sheriff Adrian Garcia spoke with media to confirm that the a 21-year-old male student is currently in custody. Of the 14 victims, two are in critical condition and four of the other more seriously-hurt victims remain stable.
"He was an eccentric kid, so a lot of people thought he was weird."
The entire campus remains closed as investigators gather evidence. Senior vice chancellor Rand Key said classes will resume on Wednesday as scheduled.
While a second accomplice was reported earlier in the day, video surveillance now suggests that only one perpetrator was involved in the seemingly random attack at the school's Health Sciences Building.
Lone Star communications student Michael Chalfan, 22, happened upon the scene Tuesday morning as he walked down the hall of the science building around 11:15 a.m.
"The first thing I saw was the suspect charging towards me," he said. "[Police] tasered him and tackled him on the ground. My friend took a picture of him and I realized I had a class with him."
"He was always in his own little world, but was super friendly."
Chalfan said the suspect — who he knew only as "Dylan" from a drama class the two had taken together a year ago — had been using a box cutter or X-Acto knife to attack students. In the chaotic aftermath, he reported seeing a woman who still had a blade stuck in her cheek.
"He was an eccentric kid, so a lot of people thought he was weird," Chalflan explained, adding that students sometimes would make fun of the suspect behind his back. "He was always in his own little world, but was super friendly."
The suspect, who was rumored to be hard of hearing, was known for his odd clothes and the pair of work-out gloves he'd always wear, according to Chalfan. He was often seen carrying a stuffed monkey toy.
