Shocked neighbours have spoken of their disbelief after a man was stabbed to death at his home in Ballymena, Co Antrim.
John Lamont, 64, was found dead and his wife Liz, 58, seriously injured, both with stab wounds, when police were called to their home.
Retired civil engineer Herbie Park, 78, who lives just 100 yards away from the couple's semi-detached house at Carnvale, off the Carniny Road on the edge of Ballymena, said: "We've had a couple of break-ins in this locality, nothing like this. But when murder lands on your doorstep it is a terrible tragedy."
Detectives arrested the couple's 26-year-old son for questioning and recovered a knife. It was taken away for forensic examination.
Police were alerted around 3am on Tuesday. They discovered Mr Lamont inside the house and his badly wounded wife nearby. Her condition was later described as "stable".
Most of Mr Lamont's neighbours in the cul-de-sac where the couple lived are middle-aged and elderly.
Mr Park added: "They're a very quiet couple. You could see them occasionally out walking the dog, but they kept themselves very much to themselves. Everybody here is in total shock. It's hard to believe something like this has happened."
