ABERDEEN, Md. (AP) -- Workers say they endured terrifying moments of wild gunfire as a woman working a temporary job at a drugstore warehouse in Maryland fired on colleagues with a handgun, killing three people before fatally shooting herself.
Authorities said the shooting, which a witness says came after an argument, erupted Thursday morning and sent screaming workers running from the Rite Aid distribution center after it ended.
Harford County Sheriff Jeffrey Gahler identified the woman as a temporary employee, Snochia Moseley of Baltimore County. Gahler says he has no motive for what he calls a "senseless crime."
The sheriff says three people were fatally shot and three more were wounded and expected to survive. He says the woman died at a hospital of a self-inflicted gunshot.
