A police manhunt is under way for a gunman who is believed to have shot his ex-girlfriend before killing her new lover.
Northumbria Police named Raoul Thomas Moat, 37, from Newcastle, as the man they want to find in connection with the incident.
He was released from Durham prison on Thursday, just hours before the shootings, having served a sentence for assault. Police warned the public that he should not be approached.
Detective Superintendent Steve Howes, who is leading the investigation, said the attack at a house in Scafell, Birtley, near Gateshead, was motivated by a grudge against the couple.
It is understood that Moat was previously in a relationship with the injured woman, who was in the house in Scafell with her current partner when the shooting took place at around 2.40am on Saturday.
The man, who is believed to be in his late 20s or early 30s and has not been named, was pronounced dead at the scene.
