BALTIMORE _ Three people were killed and others were wounded in a shooting at a Rite Aid distribution center in Aberdeen, Md., on Thursday morning, according to multiple sources with knowledge of the investigation.
The lone suspect, who was not identified, has died, according to sources. She had been taken to a local hospital in critical condition after the shooting.
Harford County Sheriff Jeffrey Gahler did not say how many people were killed.
Gahler said law enforcement officials did not fire any shots, and he declined to take questions from reporters.
Four people were taken to Johns Hopkins Bayview Medical Center with gunshot wounds; two were "very seriously injured" and two were in stable condition, said Dr. Raymond Fang, Bayview trauma medical director. One person was in serious condition at Christiana Hospital in Newark, Del.
Fang would not say whether the shooter was among those who arrived at the hospital around 10 a.m.
"To us, they're all patients," he said.
He said he was withholding their conditions because some of their families had not yet been notified.
Dispatchers received a report of shots fired at the distribution center at 9:06 a.m., Gahler said, and just over five minutes later police were on the scene.
Aberdeen is about 30 miles northeast of Baltimore. In addition to the Rite Aid warehouse, the business park's tenants are Zenith Freight Lines, TruAire, the Clorox Company and Maines Paper & Food Service. Rite Aid employs 1,300 full-time employees and 300 temporary workers at the Aberdeen facility, according to Harford County spokeswoman Cindy Mumby.
Andre Cedeno, 30, said his sister, Lela, was at the Rite Aid center.
Andre Cedeno had rushed from his own workplace 25 minutes away to try to see his sister, who was in her second week on the job at the Rite Aid center. Cedeno said she told him she ran inside and hid in a bathroom.
"She had a panic," Cedeno said. "It's crazy that people don't respect life," he said.
The FBI Baltimore office and special agents from the Department of Alcohol, Tobacco, Firearms and Explosives were also assisting in the investigation.
A reunification center has been set up at the Level Volunteer Fire Co. in Havre de Grace.
The shooting comes 11 months after a shooting at a kitchen countertop company in Edgewood, less than 10 miles away. Three were killed and two were injured in the October 2017 attack.
And, it is the third workplace shooting in the U.S. in the past 24 hours.
Four people were shot around 10:30 a.m. Wednesday at a software company, WTS Paradigm, in Middleton, Wis., by a 43-year-old co-worker, police said. The gunman was shot and killed by police. Three of the injured were in serious condition as of Thursday morning, one suffered a graze wound.
Then, around 2 p.m., four people including a police officer were shot after a man opened fire outside a judge's office in a municipal building in Masontown, Pa. The suspect, Patrick Dowdell, 61, was shot and killed by police. Dowdell had a preliminary hearing scheduled for Wednesday on domestic charges of strangulation, aggravated assault and terroristic threats from an incident several weeks ago.
Maryland Gov. Larry Hogan said he was "closely monitoring" the situation. "Our prayers are with all those impacted, including our first responders. The State stands ready to offer any support," he tweeted.
