HARFORD COUNTY, MD — A woman used a handgun to shoot seven people, three of whom ultimately died, at a Rite Aid warehouse in Perryman on Thursday. Because the shooter then also killed herself, her motives are so far unknown, but the third mass workplace shooting in Maryland in a year’s time has resurfaced a discussion about gun laws and mental health treatment.

Harford County Sheriff Jeffrey Gahler said Snochia Moseley, 26, of Baltimore County, was a temporary employee of the facility who was reporting for her normal work day when around 9 a.m. the shooting began. Two of the victims died at the scene and one died at the hospital, according to Gahler.

The shooter used a 9 mm Glock and began firing outside the building before moving inside, he added. It was not known whether the shooter had a relationship with any of the victims or if they were all employed by Rite Aid.
