New Mexico Shooting: Teen Purchases AR-Style Rifle Legally Before Killing 3 Women and Injuring 2 Officers.

The gunman who killed three elderly women and injured six others in a shooting spree in Farmington, New Mexico, legally purchased an assault-style rifle, one of three weapons he used in the rampage, a month after he turned 18. The suspect, identified as 18-year-old Beau Wilson, had no specific targets or motives, and had a history of "minor infractions as a juvenile" and was believed to have suffered from an unspecified mental illness. New Mexico has some of the least restrictive gun ownership laws in the country, with no minimum age to possess rifles and shotguns.
