The Jodi Jones murder trial has heard smoke and a strange smell was coming from her boyfriend's garden on the night her body was discovered.
Jodi Jones was 14 when she was killed in June 2003
Luke Mitchell's neighbours, George Ramage, 37, and Nicholas Frankland, 41, told the court they smelt smoke coming from the back garden.
The duo said they became aware of the smell and smoke at about 2200 BST on the evening in June last year.
Luke Mitchell, 16, denies murdering Jodi and the other charges against him.
Mr Ramage, whose home backs onto the Mitchell family home in Newbattle Abbey Crescent, Dalkeith, said he told his wife it was a strange time for them to be having a barbeque.
He had been busy doing DIY and clearing his tools away when he became aware of burning.
He told the court on Monday: "I could see it and smell it. It wasn't a food smell."
Mr Frankland, the Mitchell's next door neighbour in the same street, described seeing a brick-built log burner alight in the garden on 30 June last year.
He said the burner was "typically" used by Mr Mitchell's mother.
Mr Frankland added: "It would be just before 2200 BST.
"I might have been aware of it earlier than that but I don't recall anything specific."
He told police he heard voices but could not definitely say who the people were.
The same night, he also saw Luke Mitchell walking in the street as he settled down to watch television at about 2200 BST.
He said he had been aware of the burner before and added: "On that evening it was fairly inconsequential because it happened from time to time."
Mr Frankland's wife Patricia told the trial she first became aware of the smell of the stove between 1830 and 1930 BST and noticed it again later on in the evening.
The murder charge alleges Luke Mitchell attacked Jodi, of Easthouses, Dalkeith, in woods near Roan's Dyke.
The youngster denies that and claims that at the time he was in, or near, his home, and that Jodi, 14, was murdered by person or persons unknown.
He also denies charges of possessing knives in public places and being concerned in the supply of cannabis resin to other school pupils, including Jodi.
The teenager has lodged the special defences of alibi and incrimination.
The trial continues.
