Mother of murdered Helen McCourt says killers who don't reveal where victims' bodies are should never be freed

The law should be changed so convicted killers who do not reveal where their victims' bodies are cannot be set free, the mother of a murdered woman has urged.

Marie McCourt's daughter Helen vanished in 1988 and the 22-year-old's body has never been recovered.

Pub landlord Ian Simms was convicted by overwhelming DNA evidence of murdering her in Billinge near Wigan, but has for decades refused to say where his victim's body lies.

Ahead of his parole hearing in January, Mrs McCourt has launched a petition to bring in a law in her daughter's name, ensuring killers like Simms are not released without disclosing the information.

She said being denied a funeral for her daughter has caused "unimaginable suffering".

She said:

Mrs McCourt is asking Prime Minister David Cameron and Home Secretary Theresa May directly to "acknowledge the pain and distress caused to the families of missing murder victims", by ensuring killers who withhold information about the whereabouts of their victims are never set free.

Two other mothers whose children were killed and whose bodies have not been found are also supporting Mrs McCourt's campaign.

Jean Taylor's daughter daughter Chantel was killed in 2004 in Birkenhead, Merseyside, while Joan Morson's son Paul, from St Helens, Merseyside, was killed in 2011.

Labour MP Conor McGinn, who is backing the petition, said:
