Nehemiah Griego, 15, told police that he put several loaded weapons, including an AR-15 assault rife, into the family van with the intention of driving to the local Walmart and shooting people at random, the Albuquerque Journal reports. But Griego called a friend first, who talked him into meeting at the church where his father had been a pastor. Griego has told authorities that he was annoyed with his mother and had been having homicidal and suicidal thoughts, the AP reports. A records check found that the teen had never been in trouble with the law and no family trouble had been reported.
