The estranged husband of a school teacher has been jailed for life after admitting stabbing her to death.
Andrea Howarth's husband Jonathon has been jailed for her murder
Jonathon Howarth, 28, of Shotton Colliery, Country Durham, was arrested 350 miles away on the Isle of Wight the day after the death of Andrea Howarth.
Howarth, a Sunderland University student, pleaded guilty to murder at Newcastle Crown Court on Monday.
IT teacher Mrs Howarth, 28, was stabbed eight times. Her killer must serve a minimum of 12 years.
The court heard details of a row between the two, during which Howarth accused his wife of seeing someone else.
Neighbours heard him shout repeatedly: "Did you sleep with him?" as he inflicted eight deep stab wounds into her neck, face and shoulder close to her home in Wingate, Co Durham, in February this year.
The court also heard how after they broke up, the computing student and part-time barman used sophisticated software to monitor his wife's computer.
'Miserable and moody'
He remotely tracked her e-mails, and bought a £100 programme to monitor her mobile phone SIM card.
It led him to discover she had started a friendship with a former boyfriend from school, whose marriage was also in trouble.
Paul Sloan QC, prosecuting, told the court that the couple were different characters. He said: "Andrea was a happy, bubbly, chatty, out-going sort of person.
"The defendant on the other hand was very quiet and deep, not having a great deal to say for himself and gave others the impression of being somewhat glum, miserable and moody."
Paddy Cosgrove QC, defending, said Howarth had only brought the knife along to frighten her, but "lost all self-control".
He said: "There can be no doubt that this lady was the love of his life. What he will have to live with is that he has killed that person."
