Police have identified Darion Marcus Aguilar, 19, as the shooter who killed two people at a Maryland mall before turning the gun on himself, Howard County Police Chief Bill McMahon said today.
Police said Aguilar used a 12-gague shot gun during the incident and 16 shots were fired. In addition to the gun and ammunition, crude explosive devices made from flash powder and household items were found in Aguilar's backpack.
According to police, Aguilar entered the mall around 10:15 a.m. Saturday morning. Around 11:15, he entered the Zumiez store, a skateboard shop, on the mall's second level and fatally shot Brianna Benlolo, 21, of College Park, Md., and Tyler Johnson, 25, of Ellicott City, Md. Both were employees of the skateboard store.
McMahons said it wasn't clear if the shooter knew his victims although both Aguilar and Benlolo lived in College Park.
Aguilar then turned the gun on himself as frightened patrons ran from the area, McMahon said.
Police said they're still investigating the shooter's motive.
Police started receiving 911 calls about a possible shooting at the mall at around 11:15 a.m., and it was immediately put on lockdown, McMahon said. Police were reportedly on the scene within two minutes of the calls.
Aside from the three dead, five other people were injured. One person, who was below the Zumiez store during the shooting, suffered a gunshot wound to the foot and others had minor injuries as they ran to escape the shooting, according to police.
"All of the activity took place at one time, in one store," McMahon said.
Law enforcement sources told ABC News that one scenario being investigated was that it was a domestic dispute involving a man, his estranged girlfriend and her boyfriend.
After the crude explosive devices were found, police swept through the mall using canine units to ensure there was no other devices on the premises.
Police said the mall would reopen by Tuesday.
