The FBI says two suspects in a fatal shooting at a Denny's in Virginia are also responsible for three other robberies in the Washington suburbs.
The FBI said in a press release Friday that the duo robbed a bowling alley, a motel and a convenience store in the days before they robbed the Denny's.
The agency described the men as being in their late teens or early 20s.
The FBI said they robbed Bowl America in Manassas on Saturday. One man had a gun while the other wielded a baton. Their next target was a Manassas Comfort Inn on Tuesday. Then they robbed a Woodbridge Walgreens on Christmas Eve.
On Thursday, police said the men killed a DoorDash delivery driver and wounded another man at a Denny's in Manassas.
"They've escalated their level of violence," Prince William County Chief of Police Barry Barnard previously said at a news conference.
Yusuf Ozgur, 56, of Manassas, was at the restaurant to pick up an order for DoorDash, a food delivery service. He died at a hospital from his injuries.
A second wounded man was hospitalized with serious injuries but is expected to survive. Police did not release his name but said he is 34 and from Rixeyville in Culpeper County.
Authorities are offering a $10,000 reward for information leading to a conviction.
