COLUMBIA, Md., Jan 26 (Reuters) - Police identified the gunman on Sunday in a deadly Maryland mall shooting as a 19-year-old from the nearby city of College Park, but had no word on his motive nor whether he had any ties to the two people he shot and killed in a skate shop.
The gunman, identified as Darion Marcus Aguilar, opened fire with a shotgun in the shop at the mall in Columbia, Maryland, about 20 miles (32 km) west of Baltimore, on Saturday before apparently killing himself, police said.
Aguilar, who lived with his mother, arrived at the mall by taxi about an hour before the shooting began, Howard County Police Chief Bill McMahon told a Sunday morning news conference.
He used a 12-gauge shotgun, and fired six to eight shots, killing Brianna Benlolo, 21, also of College Park, and Tyler Johnson, 25, of Mount Airy, Maryland, police said.
Both were employees of Zumiez, a skate shop where the shooting took place. A third person was also injured.
Police arriving at the scene found Aguilar's body and his backpack filled with crude explosives, and were initially concerned he had booby-trapped himself, McMahon said. (Reporting by Alice Popovici; Writing By Jonathan Allen; Editing by Cynthia Johnston and Sophie Hares)
