The gunner opened fire at a US business park
A shooter has killed three people and wounded two others at a drugstore distribution centre in Harford County, Maryland.
Roughy 1,000 people work at the Rite Aid support facility, but the area is now believed to be secure.
"The distribution centre is where products are received and processed for delivery," Rite Aid spokeswoman Susan Henderson said.
"This is part of a large facility that is a distribution center. The shooting happened adjacent to the primary building."
We can confirm there was a shooting in the area of Spesutia Road and Perryman Road. Multiple victims. The situation is still fluid. Please avoid the area. Media staging area still TBD.

The distribution centre is located outside the City of Perryman, roughly 30 miles northeast of Baltimore.
"We are closely monitoring the horrific shooting," Gov. Larry Hogan tweeted. "Our prayers are with all those impacted, including our first responders. The State stands ready to offer any support."
