Sentencing for four of the defendants was delayed until the following month. In January 2009, Yates was sentenced to seven years, Dean Kelly to four years, and Nathan Quinn to two years. A 16-year-old was sentenced to a two-year supervision order. Parents of the gang members, including Mercer's mother and the parents of Yates, were later tried and convicted for perverting the course of justice. On 28 October 2009, Yates had his sentence increased to 12 years imprisonment, following a referral to the Court of Appeal by the Solicitor General Vera Baird QC as being "too lenient". On 2 November 2009, Mercer stabbed Jake Fahri (Jimmy Mizen's murderer), apparently having crafted a knife from a pair of tweezers.
