Ian Simms has been photographed on the streets of Birmingham after he was temporarily released from prison.
Simms was convicted of murdering 22 year old Helen McCourt in 1988 but has never revealed where he buried her body.
Helen's mum Marie has been campaigning for a change in the law which would prevent convicted killers from being released until they give up the location of their victim's bodies.
Ian Simms was photographed at a bus stop in Birmingham last week and it's understood he is being allowed out for short periods ahead of being released on license.
In a horrifying twist Marie visited Birmingham for the first time in her life on the same day Simms was seen in the city.
"To think that he could have been watching or even storking me is horrifying" Marie told Wish FM.
"I wouldn't have had a clue if he had come up and chatted. I could have been talking to him. My daughters killer.
"When they release him into the public domain he is a risk. He knows he's done it, he is a control freak and he won't tell us where she is. He's a danger to the public."
A petition calling for the introduction of Helen's Law, which would block the release of murders who conceal the location of their victims bodies, has been signed by nearly 600,000 people.
Local MP Conor McGinn has asked for an urgent meeting with the justice minister to discuss the situation.
