A Wawa in Delaware County that police say an estranged couple may have used to exchange custody of their child became the scene of bloody domestic violence as a man allegedly gunned down his ex-wife with an AR-15 rifle.

As 6ABC in Philly reports, the gunman is identified as Brian Kennedy, 34. He is accused of shooting and killing his ex-wife, 37-year-old Stephanie Miller, inside a Wawa in Radnor Township, Delaware County, late last week.

Delaware County District Attorney Kat Copeland told 6ABC Friday the killing was a cold and calculated case of domestic violence in a very public place:

"With an AR-15 he brutally murdered the mother of his child. In a public place in cold blood, placing numerous others at risk. This is a classic case of what can happen in situations regarding domestic abuse and violence with the use of firearms," Copeland said.

Details from 6ABC:

Police say Kennedy drove to the Wawa in his BMW with the AR-15 assault-style rifle in the trunk of his car.

The criminal complaint states detectives watched surveillance video of Kennedy pulling up to the Wawa in his BMW. He then retrieved the rifle from the trunk. Kennedy is then seen leaving the Wawa carrying the rifle.

The complaint also states while he was inside four Wawa employees witnessed the shooting. Some of them even recognized Kennedy as a repeat customer.

Police add that the Wawa may have been the location for a custody exchange of their child, which was why they say Kennedy could have planned the whole thing.

Miller had a previous protection from abuse order placed against Kennedy, but obviously it could not protect her life.
