The jury has retired to consider its verdicts in the trial of Dale Cregan and his nine co-defendants.
Cregan has pleaded guilty to murdering Preston educated police officer Fiona Bone and her colleague Nicola Hughes in an gun and grenade attack in Hattersley last September.
He has also accepted responsibility for the murders of father and son David and Mark Short in Manchester.
The jury must now decide whether he is guilty of the attempted murder of Sharon Hark or his co-defendants are guilty of any charges linked to the killings of the father and son.
The panel will begin its deliberations this morning following the 17-week trial at Preston Crown Court.
The presiding judge, Mr Justice Holroyd, reminded the jurors not to speak to anyone about the trial or to do their own investigations about any related matters.
