A killer who stabbed his love rival to death during sex has had two years added to his prison sentence after he tried to break out of jail.
Paul Hadden, 36, was serving a seven year term when he attacked a prison officer and tried to kick down a door in a bid to flee from Castle Huntly prison near Dundee.
A has jury found Hadden guilty of an attempted jailbreak at Castle Huntly on 17 May last year.
Hadden, who is now at Addiewell prison, was found guilty of leaving his designated area of the prison and attacking a member of staff before trying to leave via a fire door.
Solicitor Richard Lobjoie, defending, said Hadden had been taking a number of courses behind bars including Bible History, psychology and art.
The court was told that Hadden had packed up his belongings from his cell and had them in a bag when he was stopped during his attempted night-time exit by staff.
Sheriff Fiona Tait told Hadden that in light of his record and the nature of the offence she would add a further two years to his current sentence for culpable homicide.
Hadden, from Airdrie, was initially jailed for ten years for killing his partner’s ex-boyfriend after he broke into her home while they were having sex.
Hadden stabbed Iain O’Brien 21 times after the 39-year-old smashed his way into Lynn McMillan’s Coatbridge home with a baseball bat as she was having sex with Hadden.
Hadden, who was originally charged with murder, was convicted of culpable homicide at the High Court in Glasgow.
Lord Burns told Hadden: “You have been convicted of the culpable homicide of Iain O’Brien by stabbing him repeatedly with a knife and during that inflicted 21 significant stab wounds in which two went to the heart.
“I do acknowledge that this was not a premeditated attack on Mr O’Brien and evidence disclosed he came to the house of Lynn McMillan armed with a baseball bat with the intention, it was clear, of causing her and possibly you physical harm and he did to both you and Lynn McMillan albeit to a limited extent.”
During the trial, the court heard how Hadden and Ms McMillan were in a relationship for three and a half years before they split up on 5 November 2011.
She began seeing Mr O’Brien, who was her childhood sweetheart, at the end of November last year. She then split with him, claiming he was violent and aggressive when drunk.
The court heard that Ms McMillan and Hadden still had feelings for each other and got back together the following day.
Mr O’Brien refused to accept the break-up and bombarded Ms McMillan with phone calls and text messages.
Mr O’Brien used a baseball bat to smash his way into Ms McMillan’s house and found the reunited couple having sex.
During the ensuing struggle, Hadden grabbed a kitchen knife and stabbed Mr O’Brien 21 times.
