DORIS SHELLEY – Found curled in a ball in a pool of blood at her Martlesham home, the 82-year-old died from serious head injuries after being viciously attacked in February 1993.

There were no signs of her home being searched or any property taken and her death was linked to an attack on an Eyke postmistress, Susan Allum who survived a similar attack five months earlier.

More than 70 officers were investigating the murder and a £10,000 bounty was placed on the head of the killer, but still pieces of the jigsaw remain missing.

A red Sierra car was spotted on the driveway with the gates closed on the last day that Mrs Shelley was seen before her attack, but the owner has never come forward or been traced.

Two men aged 21 and 19 and two girls aged 16 and 17 were interviewed by police but never charged.

More than 3,000 people were questioned and the murder was highlighted on Crimewatch but the murderer was never found.
