Andrew Munro aged 51 was sentenced to a minimum of 27 years at Preston Crown Court for the murder of his wife Clare Munro and grievous bodily harm with intent to another individual who cannot be named for legal reasons.
Munro initially pleaded guilty to the offence on what would have been day 2 of the trial on the 3 June 2015 but decided to change his plea to not guilty before the case went any further.
After a hearing on 30 October, Judge Aubrey ordered that his original pleas had to stand and on 5 November Munro was sentenced.
Munro attacked on his 47-year-old wife on Sunday 2 November 2014 stabbing her numerous times at the family home in Culcheth Cheshire.
Emergency services were alerted when they received a call from inside the house where screaming could be heard along with the calm voice of Munro in the background.
When police officers arrived at the property they found Munro behind a summerhouse in the garden where he was arrested before being taken into custody.
His wife Clare was found in the kitchen with serious injuries but sadly she was declared dead at the scene by paramedics.
Detective Inspector Steve Jones of Cheshire Police’s Major Investigation Team (MIT) said; "This was a vicious and sustained attack on a defenseless woman, who tried despite her injuries to calm her husband down and stop any further attacks."
Munro was described as an extremely controlling man who used his expert knowledge of IT systems to keep tabs on his wife, employing various sophisticated pieces of equipment and software to follow her movements and monitor her phone and computer.
DI Steve Jones said; "As well as the loss of Claire, her family have been made to wait for justice through Munro’s continued manipulative and controlling behaviour and attempts to avoid justice. Our thoughts are with the family who have been incredibly brave through this distressing time and I can only hope that the sentence today will bring them some sense that justice has been done for her."
