A killer who stabbed her girlfriend through the heart after being taunted for being "a mummy's girl" has been jailed.
Shazia Johnston stabbed Lisa Ann Quigley to death during a row at their Fife home.
At the High Court in Glasgow on Thursday Johnston was jailed for nine years after being convicted of the reduced charge of culpable homicide having gone on trial for murder.
The 25-year-old waited 12 minutes before calling an ambulance for Miss Quigley after attacking her in Kirkcaldy. Johnston also disposed of the knife she used to kill her girlfriend on October 11, 2011. The weapon has never been found.
Temporary judge John Beckett QC told Johnston that she had carried out "a callous and calculated" killing.
Advocate Gordon Martin, defending, said: "Miss Johnston and Miss Quigley were clearly in love, but their relationship was mutually destructive. She has asked me to express her regret for what happened."
During the trial, the jury heard the couple had a turbulent relationship and their were claims that 30-year-old Miss Quigley thought Johnston was cheating on her with men. The jury heard how Miss Quigley had started yelling at Johnston on the night of the killing. When Johnston ordered her out of the flat, Miss Quigley was said to have replied: "You going to get your mummy to help. You are a mummy's girl."
On Thursday Judge Beckett told the killer: "At the age of 30 Lisa Quigley lost her life at your hands. I accept the behaviour of Miss Quigley was difficult that day. She may have pulled your hair and made threatening gestures with a knife towards you.
"However, this was a very violent killing. You stabbed her through the heart and she bleed to death. She had defensive injuries to her hands and legs which suggest she was sitting down when she was attacked.
"As she lay dying you waited 12 minutes before calling an ambulance. Her injuries were such that they were not survivable, but you did not know that.”
