A mum has told of the moment one of her sons allegedly murder the other after falling out over a dog.
William Campbell is alleged to have knifed Samuel Campbell in the chest as mum, Carolyn, tried to come between the squabbling siblings
Mrs Campbell said the alleged drunken flash point came after Campbell spoke to his brother about how he was talking to his dog, Marley.
Jurors at Newcastle Crown Court heard there had been issues over the pet previously and Mrs Campbell said it was a “sore point”.
Campbell denies murdering his younger brother, saying he impaled himself on the knife in back garden of the family home in Silksworth, Sunderland, in June.
In a video recorded interview with the police, Mrs Campbell said she was woken up after midnight by Campbell coming home because he walked into a bin as he was “a bit drunk”.
She said he asked her where “Sammy” was and she told him he was in the garden burning some wood and had been waiting to have a drink with him.
Mrs Campbell said: “I went back up to bed but I was woken up when they both came in and there were raised voices, within maybe 20 minutes, half an hour.
“I told them to keep quiet because they would disturb the neighbours. Sam and Marley, the dog, went back out in the garden.
“William shook his head and said ‘I was just telling him not to speak to Marley the way he was talking to him’.
“He didn’t say anything, he just got a bit frustrated and said ‘I’m not having this’ and ‘I’m getting a knife’.
“We went in the garden and I tried to get between them.
“Then there was a scuffle.
“I didn’t even think William had touched him.
“Sam went and took his hoodie off. He must have seen the blood on his chest. He stood there and I don’t know if he said ‘you’ve stabbed us’ or ‘come on, come on’, egging him on.
“Then Sam collapsed on William and William said ‘mam, mam, help, he’s collapsed, he’s passed out’.”
Mrs Campbell added: “Sam is a big lad. We laid him down.
“I could see there was no response.
“I went in the house and rang the emergency services but it kept saying it was busy.
“It was pitch black and I couldn’t see properly. The blood looked like it stopped.
“William said it was a bit of a flesh wound.
“I got through to the operator and they talked me through it and asked if he was breathing.
“I said he’s grunting.
“I think I said he had gone pale.
“I put him on his back and tried to do CPR.”
Mrs Campbell was asked for more background and said there had been a history with regard to Marley the dog.
She said: “There had been a big issue with Marley since I came out of hospital last year.
“He (Sam) had not been taking him out as much as he should be.
“I’ve been trying to get Sam in a proactive way, not causing an argument, telling him he should be looking after his dog.
“It’s a sore point.
“Then William shook his head and said ‘I’m not having this’ and said he was getting a knife.
“I can’t remember seeing the knife. I remember Sam egging him on.”
Asked if there had been any history of arguments between the brothers, Mrs Campbell said: “No it was more likely me that was upsetting the cart.
“They have their moments, I have to say, chalk and cheese.”
Asked if there had been previous violence between the siblings, she said there had been scuffles but nothing involving a knife.
Mrs Campbell said Sam, 24, was six foot six, taller and a bigger frame than William.
Asked about their characters, she replies: “William has got a short fuse, I might as well say that.
“Sam is a bit more placid.
“But yeah, they are chalk and cheese.”
Campbell, 26 , of Allen Court, Stokesley, North Yorkshire, denies murder.
The trial continues.
