The murder trial, presided over by Mr. Justice
Andrew Edis, began at the
Old Bailey on 10 March 2020. Bowers and Cole—both
minors at the time of the offence and originally protected by Section 39 of the
Children and Young Persons Act 1933—pleaded guilty to conspiracy to steal a quad bike Long, who was driving the SEAT, The trial was temporarily suspended on 17 and 18 March as a
member of the jury was unwell. During this subsequently abandoned trial, Thames Valley Police said they had received intelligence suggesting possible jury intimidation. A retrial began on 23 June following changes to the UK's COVID-19 lockdown. On 20 July, a juror was discharged after a prison officer reported that she had mouthed "bye boys" to the defendants in the courtroom. The following day, the 11-person jury retired to deliberate. On 24 July, the three defendants were cleared of murder. Long had pleaded guilty to, and Bowers and Cole were found guilty of, manslaughter. Harper's widow had made a
victim impact statement and later released an
open letter, in which she implored
Prime Minister Boris Johnson and
Home Secretary Priti Patel to allow a
retrial seeking a murder verdict. In his summary, on the matter as to whether the jury had been subject to any improper pressure, Edis said: "To the best of my knowledge and belief there is no truth in that at all". Harper's
MP,
John Howell, had said that he intended to ask for a review of the sentences. On 19 August, Bowers and Cole made applications for permission to appeal against their convictions for manslaughter, and against the sentences that they had received. On 21 August, the Attorney General applied for permission to refer the killers' sentences to the
Court of Appeal on the basis that they were "unduly lenient". On 28 August, Long applied for permission to appeal against his sentence, on the basis that it was too severe. The applications made by the defendants and by the Attorney General were heard by the Court of Appeal on 30 November. On 16 December the Court of Appeal dismissed: (1) the Attorney-General's application for permission to refer the sentences as unduly lenient; (2) Long's application for permission to appeal against his sentence; and (3) Bower and Cole's applications for permission to appeal against their convictions. The court granted permission for Bowers and Cole to appeal their sentences to enable the Court of Appeal to correct an error made in their sentencing for the offence of conspiracy to steal. Their sentences for manslaughter were not altered; as their sentences for conspiracy to steal and for manslaughter ran concurrently, their overall sentences were not affected. == Legacy ==
