Dale Cregan has dramatically changed his plea and admitted murdering two unarmed police officers in a gun and grenade attack. One-eyed Cregan, 29, pleaded guilty to murdering Pc Fiona Bone, 32, and Pc Nicola Hughes, 23, during his trial at Preston Crown Court. He continues to deny murdering father and son David and Mark Short. Last week the families of the two murdered policewomen sobbed in court as they listened to details of the "bloody conclusion" to Cregan's alleged string of attacks. The court heard that he told police "I'll be waiting" as he lured the unarmed and unsuspecting officers with a bogus 999 call. |
