Toni and Samantha Brown
A woman who killed her boyfriend for calling her a lesbian has been jailed for five years while her sister has been jailed for four years for refusing to call him an ambulance.
Samantha Brown, 20, from Manchester, England, stabbed Dean Darvill, 23, in the groin after he accused her of having a gay affair, The Manchester Evening News reported.
He bled to death after she fled the scene.
However, he would have survived the attack had her sister, Toni, 25, got him medical help.
Manchester Crown Court was told that Samantha Brown and Mr Darvill had been at her sister's house drinking when the incident happened in the early hours of January 9.
Police sources said that a row erupted after Mr Darvill caught her in a compromising position with another woman at the house.
Mr Darvill called Brown a lesbian after which she stabbed him in the groin with a knife from the kitchen
She then ran from the house.
The court was told that Mr Darvill begged Brown's sister to "get me an ambulance" but she refused.
She also stopped the other woman from dialing 999.
An hour later, as Mr Darvill's condition worsened, she phoned his family, who begged her to call an ambulance, but again she refused.
She would not tell them her address but said that she had also stabbed her boyfriend and that he had needed only five stitches.
She eventually called the emergency services an hour later, but by then it was too late.
Guy Gozem QC, for the prosecution, told the court: "The wound was a survivable wound. What was required was urgent medical attention, with which Dean might have lived."
He told the court that when questioned by police, Toni Brown had said she did not call the emergency services because she did not want to wake up her young children.
Judge Clement Goldstone QC said: 'How anyone can be so callous and selfish is beyond me."
Speaking outside court, Mr Darvill's uncle, Chris Mitchell, said: "We will never allow the evil act of these two despicable individuals to sully his memory."
