One-eyed police killer Dale Cregan told his mother, "I'm sorry" after admitting murder, a court has heard.
In prison conversations and phone calls from segregation at Strangeways Jail in Manchester Cregan, 29, is alleged to have "confessed and apologised" after being accused of four murders.
Mother-of-four Anita Cregan, from Droylsden, Manchester, also admitted she sent a text to Dale Cregan's girlfriend, Georgia Merriman, warning "they have got your mobile number turn it off" - so the police could not trace the signal and track him down even though "everybody was looking for him," Preston Crown Court was told.
Cregan lured Pc Nicola Hughes, 23, and Pc Fiona Bone, 32, with a bogus burglary report to a house in Hattersley before he opened fire on the unarmed and unsuspecting officers, then used his "calling card" by throwing a hand grenade at the stricken victims.
He has admitted the double murder on September 18 last year after evading a huge police manhunt. But he denies shooting dead Mark Short, 23, in the Cotton Tree pub in Droylsden on May 26 last year and the murder of the victim's father, David Short, 46, killed in a gun and grenade attack at his home in Clayton, Manchester, three months later.
Prosecutor Nicholas Clarke QC asked Ms Cregan if she was aware her son had allegedly killed David and Mark Short and gone on to murder two unarmed female police officers. She said: "Yes I do and it's very sad. He told me in prison. You need to know the full extent of this case. We got threats, the grandchildren was going to be tortured. I went in June (to the police) and did not get any help."
Cregan denies the Short murders and the attempted murder of three others injured in the pub attack along with causing an explosion and the attempted murder of Sharon Hark in a separate attack minutes after the murder of David Short.
Leon Atkinson, 35, from Ashton-under-Lyne, said to have ordered the Cotton Tree gun attack, denies the murder of Mark Short and the attempted murder of the three others in the pub at the time, along with Luke Livesey, 27, from Hattersley, Damian Gorman, 38, from Glossop, Ryan Hadfield, 28, from Droylsden, and Matthew James, 33, from Clayton, who all deny the same charges.
Anthony Wilkinson, 33, from Beswick, Manchester, admits the murder of David Short and possession of a firearm with intent to endanger life but denies the attempted murder of Sharon Hark and causing an explosion. Francis Dixon, 37, from Stalybridge, and Jermaine Ward, 24, both deny the murder of David Short, the attempted murder of Sharon Hark and one count of causing an explosion. Mohammed Ali, 32, from Chadderton, denies assisting an offender.
The trial was adjourned until Monday.
