“I didn’t know what I was doing. I was frightened and I had made a terrible mistake. He showed no fear - and was not remorseful at all,” she told the BBC.
“He was like, ‘Your children are lying’ – I froze. I wasn’t listening to his drawl. He came towards me. I had the knife in my left hand and he tried to grab it. I remember leaving.

Sands was jailed for seven and a half years for manslaughter in 2015, but served four before being released.

She sobbed as she recalled the killing and the effect the abuse and her vengeance had on her family.
“I bring life into the world. It never occurred to me that I would be guilty of taking life out of the world.”
