The suspect in yesterday's stabbing at The University of Texas has a history of mental health issues, officials said Tuesday.

UT Police Chief David Carter said in a news conference the suspect, 21-year-old Kendrex J. White, was apprehended less than 2 minutes after the stabbing death of a student. Four others were wounded in the incident.

"This was not a conspiracy," Carter said. "This was not a person that had a vendetta among any particular group."

He said White will be charged with murder and several counts of aggravated assault.

The university is no longer under any threat, the stabbing was isolated, and any incidents that occurred around the university are not related, Carter said.

The victim, Harrison Brown, was a student at UT, Carter said. Two other male victims were treated at a local hospital and released; a third male victim is still hospitalized, he said.

UT President Greg Fenves said patrols have increased on campus and west of campus.

"We are in mourning," he said. "We are hurting as a university community."

Counseling services have also been increased for students who need it, he said.

"It is hard to comprehend that in 50 years there has never been a violent murder on our campus, and to have two in one year is simply unexplainable," Fenves said, referring to the murder of Haruka Weiser on campus nearly a year ago.

Rumors on social media of another stabbing close to the university in the 2600 block of Nueces Street proved true, Austin Interim Police Chief Brian Manley said.

He said around 3 p.m. yesterday, officers were called to the scene, where the alleged victim said he got into a confrontation with a man after he watched the man threaten a woman with a knife.

Manley said during the confrontation, the victim suffered a stab wound to his lower leg, went home and asked his roommates to take him to St. David's Hospital, where APD was contacted.

A police report said the injuries were not life-threatening.

The incident at Nueces Street was not related to the UT stabbing, according to Manley. Police also found a dead body inside an apartment near campus yesterday, but Manley stressed there was nothing suspicious about the death, and it is also not related to the stabbing at UT.

Police are still looking for the suspect, who is described as a white, 5-foot-9-inch man in his 20s with sandy brown hair. He was last seen wearing blue jeans and a hoodie.
