21 year-old William Blencowe from Banbury was described by the prosecution as a “troubled young man” who was tormented by jealousy after his ex-girlfriend began a new relationship.

Connor Tremble, who was from Oxford, was stabbed on Fairacres Road in Oxford on 13th February; he was found in his social housing flat with stab wounds to is chest and legs, as well as defensive injuries to his hands. Despite the efforts of medical staff, he died when his life support was switched off in hospital two days later.

The court heard how Blencowe, who denies murder, had an “obsession with knives.” The prosecution told the court that Blencowe tracked Tremble down at his flat and then attacked him, wounding him fatally. After that, the prosecution alleges that Blencowe fled the scene of the attack and met up with two friends, Grant Clemens, 24, of Stockwells, Moreton-in-Marsh, Gloucestershire and Bradley Jones, 21, of Chipping Norton; it is claimed that these friends supplied Blencowe with a change of clothing and helped him to travel to Stratford-upon-Avon.

Mr Clemens and Mr Jones both deny a count of perverting the course of justice. Police officers investigating Mr Tremble’s murder searched Blencowe’s room at a guesthouse and found blood on a towel that proved to be a match for Mr Tremble’s DNA.

The trial continues.
