Accused made anonymous call to blame friendpublished at 11:56 British Summer Time 2 May
The prosecution closed its case on Friday morning with Det Insp Calum Meikle, the officer in the charge of the case, in the witness box.
Jurors were played a phone call made to Northumbria Police at about 21:30 BST on 23 August 2024, some 11 months after the tree had been felled and 10 months after both defendants were initially arrested.
The caller said he wanted to be anonymous, but Mr Meikle, who listened to a recording of it afterwards, told the court he instantly recognised Mr Graham's voice and a probe revealed Mr Graham's phone had called 101 at that exact time.
You can read more about what was said in the 10 minute-long call here, but in short the caller said Mr Carruthers felled the tree and was in possession of the wedge of wood taken from it, chainsaws and firearms.
Andrew Gurney, barrister for Mr Carruthers, said: "The purpose of that call really was to drop [Mr Carruthers and his friend] in it, wasn't it?"
Mr Meikle replied: "That could be a conclusion that could be drawn by the court."
The detective also agreed with Mr Gurney that there was "no uncertainty" the call had been made by Mr Graham.
