Four people are dead, and three others injured, after a shooting at a warehouse in Perryman, Maryland -- about 30 miles northeast of Baltimore.
Sheriff Jeffrey Gahler says the female shooter is one of the casualties.

She has died at the hospital." Officials say the shooting occurred at a Rite Aid distribution center.
(SOUNDBITE)(English) HARFORD COUNTY SHERIFF, JEFFREY GAHLER, SAYING: "At this time what we know is that the suspect was a temporary employee, employed here at the distribution center.
She had reported for her work day as usual and around 9am the shooting began, striking victims both outside the business and inside the facility." The suspect was armed with a handgun and several magazines, according to police, who say no shots were fired by law enforcement.
The suspect's motive is yet to be determined, but a law enforcement source told Reuters that officials believe she had a work-related grievance.
