PERRYMAN, Md.

Police said the lone suspect in the Rite Aid Distribution Center workplace shooting was a temporary employee.

Multiple police agencies are on scene at Spesutia Rd. and Perryman Rd. hours after the report was initially made to police around 9:06 a.m. The shooting was in the facility’s delivery building, police said.

The Harford County Sheriff’s Office reports there is no more threat to the community, however, police remain on scene for the investigation.

The suspect died from a self-inflicted gunshot wound.

Here’s How Families Can Find Their Loved Ones After Aberdeen Shooting

Sheriff Jeffrey Gahler said the suspect used an handgun in the shooting and had several magazines on her. She used a 9mm glock that was registered and owned by her.

It took police only five minutes to respond to the scene and he credited their training.

No shots were fire by police.

A Rite Aid spokesperson released the following statement about the shooting:

“We are deeply saddened by the events that transpired this morning at the Liberty support facility, which is part of Rite Aid’s Perryman Distribution Center in Aberdeen, Md. Local authorities have confirmed that there are multiple fatalities and casualties. 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. 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.”

Susan Henderson, spokeswoman for the drugstore chain Rite Aid, said the shooting happened on the campus of a company distribution center in Aberdeen. She described it as a support facility adjacent to a larger building. More than 1,000 people work at that warehouse.

The warehouse area is located in Perryman, a neighborhood off Route 40, in a warehouse complex.

Victims are being taken to Johns Hopkins Bayview in Baltimore and Christiana Hospital in Delaware for treatment.

A Johns Hopkins spokesperson said four adults were being treated at their hospital for gunshot wounds. He also did not confirm if one of the patients was the shooter.

He said two of the victims are in stable condition and two others are “seriously” injured.

The spokesman did say that all four people have undergone surgery due to their injuries.

Another person was taken to Christiana Hospital and is in serious condition.

Colleen Hendrickson lives and works nearby, and she thought it was a normal day while heading to catch the bus and head to work, but then someone warned her there was an active shooting nearby.

“It’s very scary when it’s just right there on your doorstep, because you can see a billion news reports about shooters, about emergency instances, and it still doesn’t make it real to you,” Hendrickson said. “I think it’s real for a lot of people right now, and there’s a lot of people still affected by this, [police] are still looking, and it’s been a few hours at this point, or about an hour and a half. It’s just insane and it’s still sinking in. It’s still crazy.”

Authorities are asking that people avoid the area as they continue their investigation. Motorists should expect traffic and delays in the area.

“It’s been absolutely crazy. Everything is cut off, all the roads are cut off. They’re not even supposed to let cars down here, and they’re just using any larger vehicles, they’re letting through,” Hendrickson said. “They’re telling some people to divert through the graveyard, somewhat. But there’s so many cars. I think I counted at least ambulances, and that’s just when I was counting.
