COLUMBIA, Md. (AP) — Police have identified the two retail employees killed in a shooting at a Maryland mall.

The Howard County Police said late Saturday that the victims were 21-year-old Brianna Benlolo of College Park, Md., and 25-year-old Tyler Johnson of Ellicott City, Md. The gunman also died.

Both worked at Zumiez, which sold skate apparel and accessories.

Police say the attack took outside Zumiez on the upper level of the Mall in Columbia, a suburb of both Baltimore and Washington.

McMahon said authorities ran into difficulty in identifying the gunman because of concerns that he might be carrying explosives.

Five other people were injured.
