COLUMBIA, Md. (AP) — 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.
McMahon said he didn’t know if Aguilar had a criminal record. No motive has been given for the shooting.
“There are a lot of unanswered questions,” McMahon said.
Very few details were released about Aguilar. He apparently lived with his mother in the suburb of College Park, where University of Maryland is located. McMahon didn’t know if Aguilar was a student there.
Aguilar took a taxi to the mall and roamed its halls before shots rang out within an hour. Police arrived at the scene just 2 minutes after a 911 call came into authorities at 11:15 a.m. When they arrived, they found three bodies at the Zumiez skateboard shop on the upper level.
