The man suspected of stabbing four students at the University of Texas says he carried a knife on campus for protection and that on the day of the attack he had walked the campus in a dream-like state.
21-year-old Kendrex J. White said in a jailhouse interview with KPRC-TV in Houston that he decided to carry a knife because his friends were carrying guns, which is permissible under a new state law allowing concealed handguns on college campuses.
One student was killed and three others injured in the May 1 stabbings.
The latest news from around North Texas.
Authorities say White suffers from mental health troubles. He's being held on a murder charge.
State law says knives shorter than 5 1/2 inches can be openly carried in public, but authorities say White was carrying a larger blade.
