On 16 December 2008, at the end of a nine-week trial in the Crown Court at Liverpool, Sean Mercer (a member of the Croxteth Crew gang) was found guilty of murder. Mercer, by then aged 18, was sentenced to life imprisonment, being ordered to serve a minimum term of 22 years, which is set to keep him in prison until at least 2030 and the age of 40. Other gang members James Yates, Nathan Quinn, Boy "M" (who could not be named as he was still under 18), Gary Kays, and Melvin Coy were convicted of assisting an offender. Another defendant aged under 18, Boy "K", later revealed as Dean Kelly, was convicted of four related offences. Kays and Coy were both sentenced to seven years.
