ABERDEEN, Maryland — Three people are dead and three others are injured from a female shooter at the Rite Aid Distribution Center in Maryland on Thursday morning.

The shooting occurred at a Rite Aid support facility where roughly 1,000 employees work.

The female shooter died of a self-inflicted gunshot wound. Law enforcement officials said the woman was a temporary employee.

Officials said the three people who survived Thursday's shooting have non-life threatening injuries.

Police were called to the distribution center at 1501 Perryman Road around 9:06 a.m. They say they were on the scene within five minutes and entered the center looking for a suspect or suspects.

The Joppa Magnolia volunteer fire company says they were one of the several units called to the "mass casualty incident", which means more than five patients are injured, not necessarily dead. At this point, three people are dead and an unknown amount of people are injured.

The Harford County Sheriff says the shooting suspect used a handgun and no shots were fired by law enforcement officers. It's still unclear as to how the suspect was injured.

The Harford County Sheriff's office along with ATF Baltimore, Maryland State Police, the FBI, and other law enforcement agencies are on the scene continuing to investigate.

“As you’ve seen when something like this happens, you can’t have enough police and you can’t have them fast enough,” said Sheriff Jeffrey Gahler.

Police released the following dispatch audio from when the shooting was first called in:

Another news conference providing updates is scheduled at Johns Hopkins Bayview Medical Center this afternoon.

Cars traveling near the Rite Aid distribution center should avoid the area if possible. Roads are closed while police investigate and Church Creek Elementary School, as well as other businesses in the area, are on lockdown.

No one is allowed in or out of Perryman Rd. Just spoke to those folks on the phone bc they weren’t allowed to walk all the way to meet me. They said they have been stuck here since the shooting and are scared after police told them they are looking for suspects @WMAR2Newspic.twitter.com/rS1tsCK2dD — Abby Isaacs WMAR (@AbbyIsaacsNews) September 20, 2018

WMAR television station also spoke with someone who works at the building next to the distribution center. He said after the shooting he was dismissed from work, but he has been stuck in the area ever since.

For those looking to meet up with family who work in the area, Sheriff Gahler says there is a reunification center at the Level Volunteer Fire Company at 3633 Level Village Rd in Havre de Grace.
