An eight-year-old Tamworth girl disarmed her stepfather who was holding a knife to her mother before he grabbed a second blade and stabbed his wife, a court heard.
The child, who cannot be named for legal reasons, then said Simon Downer told her mother: “Well that’s what happens if you push me”.
Downer (32) of Tinkers Green Road, Wilnecote, Tamworth, has denied murdering 40-year-old Tracey Downer, his wife of 64 days.
In recorded police interviews played during his trial at Birmingham Crown Court, the girl said she saw Downer hitting her mother.
She said she watched as her mother spat in his face when he was on top of her.
She said: “My mum was shouting ‘get off’ but he wouldn’t get off and he kept hurting her and then he got off her in the end.
“But then I went downstairs and he was on top of my mum.
“My mum spat in his face, she said ‘the door’s open go out’ to Simon, and I said it, and he said ‘no you do it’.
“And then he got that small knife and then was going to attack her. I took it off him and then he got a big knife from the kitchen and he stabbed her.”
The girl was asked how she managed to get the knife off Downer and she replied: “I just grabbed it out of his hand.”
In an earlier interview the girl had said her mother had accidentally cut herself in the kitchen.
And when asked why she changed her version of events, she said: “Because I was told he might get a life sentence and might never see me again.”
Tracey Downer was found dying from a single knife wound to her chest during the early hours of June 21 last year.
The court had previously heard she had met Downer when he absconded from an open prison in 2007.
The trial continues.
