Gloucester police are holding a single unidentified fingerprint taken from the house in Roman Road, Cheltenham Spa, where “Granny Aris,” as she was known locally, was murdered by an intruder. The print has been compared with 40,000 other prints, so far to no avail.

The case has gone cold for the moment, but if the killer leaves his prints anywhere else at a crime scene he’ll be charged with the murder of widow Constance Aris, who was savagely beaten to death on Thursday, February 28th, 1985.

A police spokesman said: “We still have important evidence relating to this murder, and if new information comes to light, or a specific suspect is identified, we could use that evidence to help bring that person to justice.”

That should give the Cheltenham killer something to think about.
