AUSTIN, Texas – The University of Texas at Austin campus is still healing after a stabbing spree in May 2017 that killed one student and injured several others.

The suspect, Kendrex White, was a former biology major who attacked several students with a hunting knife near Gregory Gym. White was charged with one count of murder and three counts of aggravated assault after the deadly stabbing spree.

In court on Thursday, White pleaded not guilty by reason of insanity. The prosecution will now conduct several mental health evaluations while he is in jail.

One of the victims was freshman Harrison Brown, who died from his wounds after the stabbing.

In a jailhouse interview with a Houston station, White said he didn't remember stabbing anyone, but did remembered pulling out a knife. He claimed he carried a knife for protection. White's attorneys argued that poor mental health played a part in the attack.

The mother of the student killed said she was given the blood-covered backpack Harrison was wearing the day he died. Inside the backpack she found a piece of paper with a list of the accomplishments the student would like to make.

"I feel pretty sure these were his last thoughts or goals before that day that he was murdered, and the last one is 'be happy,'" said Lori Brown.

One of the survivors described his recovery efforts after multiple surgeries.

"I got stabbed in the back in about the kidney region, and he missed my kidney and my spine and spinal cord by a few millimeters on either side," said UT student Stuart Bayliss. "And then I wound up pulling the knife out and he pulled the knife from my right hand and cut seven of the eight tendons."

White will be back in court on May 8 where prosecutors will present the results of the mental health evaluations.
