The suspect believed to be responsible for a fatal stabbing spree at the University of Texas Austin campus on Monday has a history of mental health issues, police say.

According to the Dallas News, Kendrex White, 21, has been arrested on murder charges after killing one student and injuring three others with a knife outside the Gregory Gym at the center of campus on Monday.

Police told the Dallas News that White had recently been committed to a mental health facility in a city other than Austin for unspecified psychiatric issues.

“His motivation, what was going through his mind, I can’t answer at this time,” UT Police Chief David Carter told reporters. But he said there was no truth to the rumor that White may have been targeting specific groups, including fraternities.

“None of the victims in this case were wearing anything that would indicate they were members of a fraternity,” Chief Carter said.
