Mall Shooter Described As "Mall Rat"

(Columbia, MD) -- The 19-year-old who killed two people and himself at a Maryland mall on Saturday is being described as a "mall rat." The "Washington Post" reports that an employee of the store where the killings took place says Darion Aguilar was often at The Mall in Columbia. The employee told the "Post" that Aguilar would occasionally come into the store and browse. Police are still looking for a motive into why Aguilar opened fire at the skate shop at the mall. An autopsy indicates Aguilar stuck the barrel of his shotgun in his mouth before pulling the trigger and killing himself.
