A spokeswoman said: "Police believe this has been a targeted, domestic-related incident."
The scene was heavily guarded by police today and a white forensics tent had been set up in the front yard of the brick-built terrace house.
One woman in a nearby property, who declined to be named, said: "All I saw were lots of blue lights and this morning they said someone had been murdered - a lass, I think.
"It's a good estate - you don't expect this."
