The mother of a murder victim wants her killer charged for not revealing where he hid her daughter's body.
Mrs McCourt said she might consider a private prosecution
Mari McCourt, from Merseyside, said Ian Simms is preventing the proper burial of her daughter Helen.
Pub landlord Simms is serving a life sentence in prison for killing Helen in February 1988.
However, because he has consistently protested his innocence, Helen's body has never been found.
Mrs McCourt, from Billinge, near St Helens, said if the Crown Prosecution Service does not charge Simms she will consider a private prosecution.
On Monday she told BBC Radio Merseyside she has been unable to get on with her life for 15 years.
Simms was jailed for the killing of Helen in 1988
"For [Simms] to be released without revealing where Helen's body is and not showing at least that tiny bit of remorse, in the name of humanity it would be the greatest injustice," she said.
"Please just let me know where Helen's body is buried, just let me be able to give her a burial.
"And then he and I can go forward with our lives."
Simms is currently serving his sentence at Frankland Prison, Durham, and will be eligible for parole in 2004.
The Crown Prosecution Service said it would be difficult to pursue a case against him, based on the facts arising from his trial.
