A female employee at a Maryland distribution center committed suicide after killing three people and wounding three others in a mass shooting Thursday, police said.

Hartford County Sheriff’s Office confirmed that 26-year-old Snochia Mosele from Baltimore County shot six people at the Rite Aid Distribution Center in Aberdeen, Maryland 30 miles northeast of Baltimore. Police responded to reports of a shooting at 9:09 a.m., according to a spokesperson for the sheriff’s office.

Police said the suspect was armed with one handgun and several magazines of ammunition. The woman was a temporary employee of the distribution center and had reported to work on Thursday. No shots were fired by police officers.

The sheriff’s office warned people to stay away from the area earlier on Thursday.

The shooting marks the third violent incident in Harford County in recent years. Three people were killed and two others were wounded in a shooting at a business park in 2017, and two sheriff deputies were fatally shot at a Panera in 2016.

Maryland Gov. Larry Hogan said his office is “closely monitoring” the situation.
