Nazir Afzal, Chief Crown Prosecutor for CPS North West, said:
“The Crown Prosecution Service and Greater Manchester Police have been determined to bring to justice all those involved in the four murders and the attempted murders in this case.
“The murders of all four victims, Mark Short, David Short and Police constables Fiona Bone and Nicola Hughes, were nothing short of executions - planned, premeditated and cold-blooded. The blatant use of firearms and grenades put members of the public at risk of significant harm and caused fear amongst local communities.
“This has been a hugely challenging case both in its scale and complexity. Through painstaking analysis of a huge amount of evidence the CPS, prosecuting counsel and police have left no stone unturned to piece together the events and to prove who was responsible. The timescale within which a case of this size, involving so many defendants and so many murders, was brought to trial was exceptional and that was down to the dedication and commitment of everyone in the investigation and prosecution teams.
“I would like to take this opportunity to thank all the witnesses from the local area who spoke to police, gave a statement or had the courage to give evidence at court. Their support and assistance has been vital to securing these convictions.
“Above all our thoughts remain with the families and loved ones of the victims at this extremely difficult time.”
