Rose West drove her serial killer husband Fred to rape and murder more girls

Rose West’s youngest son will speak out for the first time as it is revealed his mother may have driven her serial killer husband to kill more girls in a new documentary.

The twisted couple’s son, Barry, will speak about his parents in an upcoming film by Sir Trevor McDonald.

He said in 2004, that when he was seven, he heard his mother attacking his older sister Heather – who was one of 12 known victims of the couple.

Their youngest son said Rose ‘[stamped] on her head five times. She didn’t move again’, the Sunday Express reported.

Barry was one of five West children taken into care in 1992 after a sexual abuse case was opened against their parents.

Tara, Louise, Rosemary junior and Lucyanna were also removed from the household by the local authority. 

The new documentary will reveal how Rose was ‘actively involved’ in her husband’s murder of at least a dozen girls and young women.

Nine of their victims were buried at 25 Cromwell Street, Gloucester between 1967 and 1987. 

Rose still denies her role in the murders but Sir Trevor’s documentary will suggest she is just as violent as her husband was.

Although the mother was only fifteen when she met Fred, who was 27 and had already killed, psychologist David Canter believes she may have played a leading role in the relationship from the outset.  

‘Rose West was not a bystander’, said Sir Trevor, 79. ‘She was deeply involved. In any normal situation you would think that a wife’s influence would curb Fred’s horrific tendencies but we learn that she was actively involved.

‘When they cruised around to pick up people, she was the one who probably convinced the girls to get in the car.’  

The documentary will also reveal how Rose West (pictured right with husband Fred left) was ‘actively involved’ in the crimes in which girls and young women were murdered

The former broadcaster, who will present new evidence in the show, also visited the ‘eerie’ site of the Cromwell Street ‘House of Horrors’ and met the families of victims.

Jayne Hamer, a former Cromwell Street lodger, will describe hearing screams from the cellar and tell Sir Trevor how she feels lucky to have left the house alive. 

The documentary will also feature the first television interview of the sisters of Juanita Mott.

Juanita went missing in 1975, aged eighteen, and her remains were among the nine found at Cromwell Street in 1994. Three more sets of human remains were found elsewhere, bringing the total number of victims to twelve.  

British-Trinidadian broadcaster Sir Trevor McDonald will present new evidence on Rose and Fred West when the documentary airs on Thursday

Rose West, 65, was convicted of 10 murders and is one of a very few female prisoners with a whole life tariff meaning she will die in prison. 

Her husband, Fred, confessed the killings in 1994 and committed suicide while on remand at HMP Birmingham a year later.

Fred and Rose West: The Real Story with Trevor McDonald will broadcast on ITV on Thursday, January 31 at 9pm.
