The parents of a young man suspected of stabbing four students at the University of Texas apologized for his actions and said his behavior turned erratic after a car crash weeks before the Austin campus attack.
Kenneth and Shantina White told KVUE-TV and the Austin American-Statesman that it was "frightful" to see their son's behavior and that they had sought psychiatric care for him.
Kendrex White was charged with drunken driving following the accident and his parents wonder whether a head injury may have contributed to the change in his demeanor.
Authorities said the 21-year-old Kendrex White fatally stabbed one person and injured three others May 1 before police disarmed him. He is charged with murder.
Police said the day after the stabbings that White suffered from mental health troubles.
