[Ed. – Police now know who, just not why]
Police have identified the gunman in the Maryland mall shooting as a 19 year old from suburban Washington.
Howard County Police Chief William McMahon said Darion Marcus Aguilar of College Park, Md., arrived at the mall shortly after 10 a.m. on Saturday armed with a Mossburg 12-gauge shotgun and used it to kill two people at a store on the upper level of the Mall of Columbia before killing himself.
McMahon said police are trying to determine whether Aguilar knew either of the victims.
Police identified the victims as 21-year-old Brianna Benlolo of College Park, Md., and 25-year-old Tyler Johnson of Ellicott City, Md. Both worked at a skateboard shop called Zumiez.
It took hours to identify the shooter since he was carrying ammunition and a backpack and police thought he may have had explosives, McMahon said.
“When we originally found the shooter, he still had a lot of ammunition on his person,” McMahon said.
