Jan. 28 - Maryland mall shooter was polite and showed no signs of mental illness when he bought the weapon used in the shootings, according to gun shop owners. Linda So reports.
This is the store where 19-year-old Darion Aguilar bought the shotgun he used in the shootings at the Mall in Columbia, Maryland. Owners at the United Gun Shop in Rockville say they were surprised when they heard Aguilar was the shooter. They say he was polite, mild-mannered and asked questions about gun safety when he bought the rifle early last month. Owners say he was looking for a shotgun for home defense and showed no signs of mental illness. When they ran a background check on him, no red flags were raised. Police say Aguilar, armed with the shotgun, walked into the Maryland mall on Saturday and killed two employees at the Zumiez skate shop before killing himself.
