US woman shoots colleagues, herself

Perryman – A woman armed with a handgun opened fire on Thursday on co-workers at a Maryland distribution centre for the Rite Aid drugstore chain, killing three people and wounding three others before taking her own life, the Harford County sheriff, Jeffrey Gahler, said.

The killer was identified as Snochia Moseley, 26, a resident of Baltimore County.

Investigators had not yet determined a motive, but the shooting was believed to have been sparked by a work-related grievance.

The fact that the assailant was a woman was unusual, given that the overwhelming majority of mass shootings in the US are committed by men.
