Snochia Moseley was working at the time she opened fire.
A Maryland woman who opened fire at a Rite Aid distribution center on Thursday has been identified by authorities.
Snochia Moseley, 26, was reportedly working temporarily at the Aberdeen location when she came into work and shot six co-workers, three of whom were killed, before she turned the gun on herself.
She was in critical condition and later died at a local hospital, police said.
Moseley opened fire outside the building just after 9 a.m. and then moved inside and kept shooting, Harford County Sheriff Jeffrey Gahler said during a press conference.
Authorities said the weapon Moseley used, a 9mm Glock handgun, was registered and owned by her. A motive for the shooting isn’t known.
A co-worker described Moseley as “nice person,” but said she came in Thursday in a “bad mood.”
“She wanted to pick a fight,” Mike Carre told the Washington Post. “And then she started shooting.”
Rite Aid employs 1,000 full-time, 300 temporary and 30 part-time employees between its two distribution facilities in Perryman, a spokesperson for the company said.
The shooting comes after three co-workers were killed just 10 miles away at a kitchen countertop company 11 months ago.
“We stand here yet again,” Gahler said Thursday.
