HOUSTON — A man accused of stabbing more than a dozen people at a Houston-area college told investigators that he had fantasized about cannibalism and necrophilia and about cutting off people’s faces and wearing them as masks, according to a court document made public on Thursday.

Dylan Quick admitted to an investigator that about week before the attack at Lone Star Community College in Cypress he had researched mass stabbings on his home computer, according to a search warrant affidavit.

“He stated he had read numerous books about mass killings and serial killers which are also located at his residence,” the affidavit said.

Quick is being held without bond on three counts of aggravated assault for Tuesday’s attack at Lone Star Community College that injured 14 people. Only one person remained hospitalized Thursday, and that person was listed in good condition.

The affidavit listed nine items that were seized from Quick’s home, including one listed as “Hanibal Lecter Mask.” Hannibal Lecter is the cannibalistic serial killer from the film “The Silence of the Lambs.”

Also among the nine items seized were an animal dissection kit and several books including one called “Hit List” and another titled “Hitman.” The affidavit does not say what the books are about.

The affidavit said Quick told the investigator that in preparing for the campus attack, he had sharpened things, including a hairbrush and pencils, to use as weapons.

Authorities have said Quick used only a razor utility knife to slash at his victims on two floors of the college’s health science building.

After a brief court hearing earlier Thursday, Jules Laird, Quick’s attorney, said he was still looking into Quick’s background but that he didn’t think the 20-year-old had a history of mental illness or had taken any medication to treat such a condition.

He said Quick was on suicide watch and will stay in jail as he undergoes a psychological evaluation.
