COLUMBIA, Maryland (USA TODAY) - Police in Columbia, Md., have identified 19-year-old Darion Marcus Aguilar as the suspect in Saturday's shooting at the Mall in Columbia.
Howard County Police Chief Bill McMahon said Aguilar, who lived in College Park, Md., fatally shot two people at a store before killing himself.
Police are trying to determine whether Aguilar knew either of the deceased victims, who are identified as Brianna Benlolo, 21, of College Park, Md., and Tyler Johnson, 25, of Ellicott City, Md.
"We have not been able to verify any type or relationship between him and our victims," McMahon said. "That is an open question."
McMahon said the shooter used a 12-gauge shotgun to kill the two victims. Another victim was shot in the foot.
Aguilar arrived at the mall by cab around 10:15 am. Reports of shots came in an hour later.
Between six to eight shots were fired during the shooting, said McMahon.
Aguilar carried a backpack that had homemade explosive devices. He also carried a great deal of ammunition, said McMahon during a Sunday morning press conference.
The mall, which is now closed, is expected to reopen by Tuesday, said McMahon. There will be grief counselors on site there as Saturday shoppers come back on Sunday to pick up the belongings they left in the mall during the panic of the shooting.
When the mall reopens, there will be a "strong police presence."
