As with all unsolved murder investigations, the Brumhill case has been subject to regular reviews throughout the last 20 years.
And with significant advances in forensic techniques since 1993, the East Midlands Special Operations Unit Review Team in 2013 conducted a thorough review of the case, which led to the submission of a number of items for further examination.
Although it is not known what was being analysed by the unit’s team, the repeated police appeals following the killing revolved around the missing murder weapon and a bloody footprint that was left on the window sill of the shop, which backed onto Billing Road cemetery.
Det Insp Louise Hemingway, of the East Midlands Special Operations Unit, said at the time: “Unfortunately not every murder is immediately solvable, but our commitment to bringing the offender to justice remains as strong as it did 20 years ago.
“We never forget that behind every murder there is a family who continue to live with the trauma and pain such a death brings.”
Speaking after the investigation was relaunched, Mr Brumhill’s daughter, Sue Blake, said: “Though my father was murdered 20 years ago, not a day goes by when I don’t think of him and of the brutal way his life was ended.
“If anybody has any information they have been withholding over the past two decades for whatever reason, please please come forward. It could be the missing piece of the jigsaw the police need, so that as a family we can at last have some closure.”
