(COLUMBIA, Md.) -- A shooting incident at a crowded Maryland mall left three people dead Saturday morning and police are still trying to determine the gunman's motivation. After receiving 911 calls from The Mall in Columbia, authorities later discovered the bodies of Brianna Benlolo, 21, and Tyler Johnson, 25, inside the apparel store Zumiez.
That's where they also found the shooter, Darion Marcus Aguilar, 19, who died as a result of a self-inflicted wound from the same 12-gauge shotgun he used to commit the murders. Another person received a gunshot wound to the foot but was expected to recover. There were also four people who were treated for non-life threatening injuries resulting from the chaos that ensued as a result of the shootings.
Police also say a search of the shooter's bag found inside the store revealed two crude devices that appeared to be an attempt at making explosives using fireworks.
Howard County Police Chief Bill McMahon told reporters, "We have not verified what the motive is. It may be that it is a domestic situation."
On Sunday, McMahon said a search of Aguilar’s home turned up a journal that “does express some general unhappiness with his life, but I really don’t have any other information about that now."
Benlolo had worked at Zumiez since November 2012 and was the mother of a small boy. Johnson worked there for three months.
The two-story mall in Columbia, Md., is located about 40 minutes outside of Washington, D.C. The mall tweeted on Sunday that it will reopen Monday at 1 p.m.
