The man who admitted killing former Island resident police officer Fiona Bone confessed to a psychiatrist, a court’s heard.
Dale Cregan has admitted killing 32-year-old Fiona and her colleague Nicola Hughes in a gun and grenade attack in Manchester last September.
Preston Crown Court has been hearing evidence from forensic psychiatrist Dr James Collins, who interviewed Cregan while he was on remand.
Cregan, aged 29, denies murdering two other men, attempted murder and causing an explosion.
Dr Collins said Cregan told him he shot David Short point-blank in the head three times, adding if he’d had time he’d have decapitated him.
Cregan claimed Mr Short had threatened his family and he’d felt determined to kill him, and justified.
Just ten weeks later, he’s alleged to have shot and killed Mr Short’s father before going on the run.
PC Fiona Bone and PC Nicola Hughes were killed in a grenade and gun attack after Cregan lured them into an ambush.
The case continues.
