Investigation reveals far-right ties of hero officer in Allen mall shooting.

The shooter who killed eight people at a Dallas shopping mall had neo-Nazi beliefs and brought eight legally purchased guns to the scene, according to authorities. The shooter, Mauricio Garcia, was shot dead by police within four minutes, and the officer who killed him is being hailed as a hero. Garcia apparently chose his victims randomly, and investigators are still trying to determine his motive. Garcia had no criminal history before the attack, but he had a history of mental health issues and was discharged from the Army in 2008.
