HARFORD COUNTY, MD — A shooter opened fire Thursday at a Rite Aid warehouse in Perryman, killing and injuring several people. Seven people were shot, and four of them died, including the shooter, Harford County Sheriff Jeffrey Gahler said at a press conference Thursday afternoon. Names are not being released pending next-of-kin notifications.

The suspect — Snochia Moseley, 26, of Baltimore County — died at the hospital from a self-inflicted gunshot wound, according to the sheriff’s office. She was a temporary employee of the facility who was reporting for her normal work day on Thursday morning when around 9 a.m. the shooting began, he said. There are multiple addresses for the suspect, Gahler said, adding: “We are chasing all leads” for information about her.

Two of the victims died at the scene and one died at the hospital, according to Gahler.
