Several people were injured on Thursday in a shooting in Harford County, Maryland, according to authorities.
“At this time I can confirm multiple wounded and multiple fatalities,” Harford County Sheriff Jeff Gahler said at a Thursday press conference.
According to CNN, the shooter killed three people and wounded two others. The shooting occurred at a Rite Aid distribution center.
Gahler said that law enforcement responded to a call at 9:06 a.m. The Harford County Sheriff’s Office wrote on Twitter around that time that the “situation is still fluid.” Gahler reiterated that message at the noon press conference.
“We are so preliminary into this investigation,” he said. “We are going to give you as much information as we can right now even though it’s very preliminary and very limited.”
Shooting suspect in custody: Harford County Sheriff
Officials believe that the shooter acted alone and that the lone suspect is in custody and in critical condition at an area hospital.
Agents from the Baltimore offices of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and the FBI also responded to the shooting, per the sheriff’s office.
The Rite Aid distribution center is in Aberdeen, about 32 miles northeast of Baltimore. The area of the reported shooting includes a church and a business district. It is near the Aberdeen Proving Ground, a large Army facility where military technology is developed and tested, according to Harford County’s website.
Maryland Governor Larry Hogan said on Twitter Thursday morning that his office was “closely monitoring the horrific shooting.” He offered state resources to Harford County as it continues to deal with the situation, officials said.
“Our prayers are with all those impacted, including our first responders,” Hogan wrote. “The State stands ready to offer any support.”
The shooting occurred a day after a man shot and wounded four people, including a police officer, at a Pennsylvania court building before he was killed by police, according to Pennsylvania State Police. On Wednesday, a shooter also injured four people in Middleton, Wisconsin.
