The man who fatally shot five people and wounded six more in Aurora, Illinois, on Friday was armed with a handgun he should not have been able to purchase, local authorities have revealed. The shooter, identified as Gary Martin, was convicted of aggravated assault in Mississippi in 1995, said Aurora Police Chief Kristen Ziman. That felony conviction should have been detected by the background check Martin underwent to purchase his gun. It was not. Though a second background check for Martin's concealed carry permit application did alert to his record, he already had the weapon in his possession by that point.
