Graham Gibson cleared of Christine Henderson murder
A Teesside man who stabbed his estranged partner 12 times has been cleared of her murder.
Christine Henderson, 50, was found at a friend's house in Cherwell Terrace, Brambles Farm, Middlesbrough.
Graham Gibson, 47, of Kent Avenue, Hartlepool, admitted manslaughter, saying he killed Mrs Henderson in "60 seconds of madness" on the night of 1 to 2 July.
He will be sentenced at Teesside Crown Court in two weeks' time.
The jury heard Gibson had been provoked by his former partner following an argument and lost self-control.
He claimed the mother-of-three had been taunting him about a previous partner.
The attack was described as "brutal, frenzied and sustained".
Gibson stabbed Christine Henderson 12 times in the head, neck and chest and left her bleeding to death on the floor.
He then searched her handbag for money, waiting more than half an hour before he "calmly" and "without emotion" called 999 to report what had happened.
The court was shown CCTV of Gibson walking the streets minutes after the attack.
Witnesses said he looked "happy" and "was grinning".
