Simon Everitt's body was found three weeks after he vanished
The sister of a man accused of murdering a teenager has told Norwich Crown Court he admitted to the killing.
The body of Simon Everitt, 17, was found near Great Yarmouth three weeks after he vanished in June 2008.
Jonathan Clarke's sister Christina told jurors he said he had tricked Mr Everitt into going with him, doused the teenager in petrol and set him on fire.
Mr Clarke, 19, from Shropshire, Jimi-Lee Stewart, 25, and Maria Chandler, 40, both from Norfolk, deny murder.
Mr Clarke's sister told the jury she had heard the body was then dumped in woods.
Earlier another witness, a youth who cannot be named for legal reasons, gave evidence.
He said Mr Clarke told him he wanted to kill Mr Everitt.
The youth said that Mr Clarke told him he wanted to put Mr Everitt in his car and bury him in Fritton Woods.
He also described how Mr Clarke asked him for a spade and talked about burning some clothes.
The case continues.
