( CNN ) -- As victims of a stabbing attack at Lone Star College near Houston recover physically and psychologically , the suspect in the incident waived his right to a court hearing Thursday , CNN affiliate KHOU said . Dylan Quick , 20 , had been scheduled for a probable cause hearing , but he waived his right and did not appear in court , the station said . He remains in jail and under a suicide watch , his attorney said , according to KHOU . He is charged with three counts of aggravated assault with a deadly weapon in Tuesday 's attack , in which 14 people were wounded -- at least some of them with a utility knife . Two of the 14 people attacked remained hospitalized Wednesday , while others were out , dealing with the aftermath of the attack . `` I keep going over it . I see him coming at me , '' stabbing victim Andrea Cervantes told CNN affiliate KPRC . According to authorities , Quick attacked people on two floors of the school 's health science center Tuesday . Witnesses to the stabbings described a chaotic scene as bleeding victims collapsed to the ground and students and teachers ran for cover . `` It just seemed like he was just going around , basically getting whoever was more open and easiest for him to reach , '' witness Cassie Foe told CNN 's Anderson Cooper on Tuesday . The attacker was aiming at people 's necks and faces , student Melody Vinton told KHOU . One woman had what appeared to be the blade of a box cutter sticking out of her cheek , she said . Witness Steven Maida said he and other students chased Quick down and pinned him to the ground until authorities arrived . After his arrest , Quick told police he had had fantasies of stabbing people since he was 8 , Harris County Sheriff Adrian Garcia told reporters . He had been planning Tuesday 's attacks `` for some time , '' Garcia said . A search warrant affidavit said that Quick told police that he also had fantasized about `` cutting off people 's faces and wearing them as masks '' and about necrophilia and cannibalism . He also told police that he had researched mass stabbings , the affidavit said . Quick underwent a psychological evaluation Wednesday , according to the Harris County District Attorney 's Office . Three people hurt in the stabbings were discharged from a Houston hospital Wednesday , while two others remained there in good condition , hospital spokeswoman Kathryn Klein said . The campus was shut down , and it reopened Wednesday , a day after the attack . Quick has intense ties to the school . Born deaf , he received a cochlear implant at age 7 . The implant gave him the ability to hear , but he then had to learn how to speak . His mother home-schooled him and got him involved in Lone Star 's library programs when he was a teen , according to CNN affiliate KPRC . A profile on a student blog recounts how joining a campus book club changed his life . He rarely spoke during his first two years in the library 's teen activities program , according to the profile . `` But after those two years it was if a floodgate had opened up and Dylan became loquacious , sharing his analyses of literature and socializing with his book club comrades , '' the blog article says . `` His room at home , he explains , barely contains his 1,000+ collection of books . In the future he plans to build and host an online international book club to connect people of all ages from around the world , '' the profile says . The teen book club on campus encourages youths to enroll in the community college after high school graduation , and Quick did . Some faculty members said Quick was a good student there , Lone Star College-CyFair President Audre Levy told reporters Wednesday . Also , staff members at the county library branch on campus , where Quick worked part-time for about a year , `` had fond things to say of him , '' Levy said . `` So many are surprised '' that he was the suspect , she said . Quick was planning to finish his associate degree at the college and then transfer to the University of Houston to study accounting . Tuesday 's incident came more than two months after three people were wounded in a shooting at a different Lone Star College campus -- the North Harris campus in Houston . CNN 's Ed Lavandera , Joe Sutton , Jason Morris , Dave Alsup , Chandler Friedman , Paul Caron , Chuck Johnston , Ashley Fantz and Jason Hanna contributed to this report .
