Kendrex J. White, the suspect in a hunting knife attack that left one student dead and three others wounded at the University of Texas at Austin, may have been "suffering from mental health issues," UT Austin Police Chief David Carter said Tuesday. White recently had been involuntarily committed and later released in another city, according to Carter, who provided no other details. Armed with a "bowie-style" hunting knife, the suspect "calmly walked around" campus Monday afternoon and randomly stabbed other students, police and witnesses said. White, who was booked on a murder charge, will face additional counts, authorities said. The stabbing attack does not appear to be part of a larger assault, though authorities were still trying to determine a motive.
