Police in Maryland early Sunday identified the gunman in a deadly shooting at The Mall in Columbia, between Washington, D.C., and Baltimore.

Howard County Police Department Chief William McMahon identified the shooter as Darion Marcus Aguilar, 19, of College Park, Md.

“It took us a while to identify him,” McMahon told reporters. “We were concerned about whether he had boobytrapped himself.”

Aguilar’s body was not boobytrapped, McMahon said.

However, a backpack was found at the scene containing “homemade” explosive devices consisting of gunpowder and household items.

Police said two employees of Zumiez, a skate shop, were killed in the Saturday morning shooting before the gunman killed himself. Five people were injured.

“We have not be able to verify any relationship at this point” between Aguilar and the victims, McMahon said.

“We do know that one of our victims also lived in College Park,” he said, but added that may be a coincidence.

Authorities late Sunday said Aguilar did not have a criminal record and released a photo of him.

McMahon said officials recovered ammunition, computers and documents while serving a search warrant at Aguilar’s home.

A 12-gauge shotgun used in the shootings was apparently purchased in Montgomery County, Md., in December, McMahon said.

“Our hearts and prayers go out to the victims and their families and their loved ones,” Howard County Executive Ken Ulman said at the news conference.

“We’re better than this,” he added.
