The man who police say killed two women at a Louisiana movie theater was able to legally buy a gun because there was never an order to have him hospitalized for psychiatric care against his will, Georgia state authorities said on Monday.

Suspect John R. Houser, who killed himself after Thursday's rampage in Lafayette, Louisiana, purchased the weapon he used in the attack from an Alabama pawnshop in 2014, authorities say.

Houser made the purchase even though there was a 2008 court order in Georgia that sent him to a mental health facility due to his "volatile mental state."
