Thirteen years ago in mid-December Marie was abducted, strangled and buried in a bog drain.

Her body was not found until six months later.

The baby she gave birth to only discovered the truth six years ago.

Aine Kilmartin, now aged 26, never had a chance to know her biological mother. By the time she was old enough to start asking questions, Marie was long dead. Now instead of searching for her roots, Aine is searching for justice.

"The person who murdered her and left her with a slab on top of her must have a very hard heart.

If you were in my position . . . to never have got the opportunity to know your mother because someone took her away . . . I think you would feel exactly the same, " she said. Her mission now is not just to find Marie's killer. In her well constructed and articulate website Aine cites her objectives as increasing awareness about unsolved murder cases and offering "a semblance of hope of justice for the unforgotten and their families and friends."

She writes: "As awful as it sounds, that murderer has every chance of re-offending and the next victim has every chance of being your mom, a loved one, a friend, or even you." It's a chilling thought but the reality that Aine and many other families of missing people and unsolved crimes have lived through and continue to endure as each year passes.

Somebody somewhere knows something about Marie Kilmartin's murder . . . and the many other unsolved murders on garda files. Crimestoppers is offering a 10,000 reward in the case of Marie Kilmartin and the cases of seven other missing women.

Aine Kilmartin is right when she says her mother's killer must have a very hard heart. Her website can be found at www. imom1512. com.
