POLICE are offering a £50,000 reward for information that will help them bring a schoolgirl's killer to justice.

Lisa Hession, aged 14, was murdered on her way home from a house party on Saturday, December 8, 1984.

She was strangled a short distance from her home on Bonnywell Road in Leigh at around 10.30pm.

Lisa was then discovered shortly before midnight by a dog walker on Rugby Road.

A full investigation into her murder took place, but the attacker was never found.

Head of GMP's Cold Case Unit, Martin Bottomley, said: “This case has been subject to a number of reviews since 1984, so that we can find the answers Lisa’s family so desperately deserve.

“The reviews have concentrated on using advances in forensic techniques and investigating all the information we have received from members of the public so far.

“While we have not found the answers yet, this case will remain open until Lisa’s killer is found and brought to justice.

“Even though this happened 33 years ago, I’m sure that someone who lived in the area at the time will know something that could help our investigation.

“Anything you know, no matter how insignificant it may seem, could be the key to uncovering who is responsible for Lisa’s death.”

Anyone with information is asked to contact 0161 856 5961 or make a report, anonymously, through the independent charity Crimestoppers on 0800 555 111.
