Employee kills 3 at Rite Aid warehouse in Maryland (VIDEO)

A temporary employee opened fire at the Rite Aid warehouse where she worked in Maryland on Thursday morning, killing three and injuring three others.

Harford County Sheriff Jeffrey R. Gahler confirmed 26-year-old Snochia Moseley, of Baltimore County, arrived at work shortly after 9 a.m. armed with a 9mm Glock handgun. For reasons still unclear to investigators, she began shooting coworkers gathered at the 210,000 square foot facility near Aberdeen, striking six others before turning the gun on herself.

“She had reported for her workday as usual, and around 9 a.m. the shooting began, striking victims both outside the business and inside the facility,” Gahler said. “We do not at this time have a motive for this senseless crime.”

Susan Henderson, a Rite Aid spokeswoman, told the Associated Press the building where the shooting occurred served as a support facility for a nearby larger building. The company said on social media the incident left them “deeply saddened.”

“We are continuing to work closely with authorities as they conduct their investigation. The facility has been closed, and we are assessing when it will be reopened,” the statement concluded. “Grief counselors will be made available to our associates and will remain available as long as they are needed. Our thoughts and prayers go out to all those involved in this tragic incident, as well as their loved ones.”

Harford County Executive Barry Glassman lauded the response to the incident, saying emergency personnel “performed perfectly.”

“Unfortunately, we have become accustomed to this,” he said. “Although this is the unpredictable, we train for the unpredictable … we’ve got a lot of problems in this country to solve to bring these incidents to a closure.”

Maryland Gov. Larry Hogan likewise extended thoughts and prayers to the shooting victims. “I remain in close contact with Harford County officials and state and local law enforcement as they continue to investigate,” he said.
