Dyfed Powys Police cold case review of unsolved crimes
A cold case review team has been set up to investigate unsolved crimes by Dyfed Powys Police.
Among the cases under investigation is the attempted rape of an elderly woman and a burglary at her home in Milford Haven in 1994.
New forensic evidence has been obtained to help officers as the culprit was never found. The victim has since died.
Part of the team's role is to look at whether modern technology can be used to solve old crimes.
Police say the Major Crime Support Team will provide assistance on major incidents and investigations to minimise impact on day-to-day policing, as well a reviewing unsolved serious crime.
"Serious unsolved crimes are never closed in Dyfed Powys Police and we continue to review and investigate them in a bid to get justice for the victims and their families," said a force statement.
It says the force has already had success with cold case reviews.
In one, labourer John Cooper, 66, was jailed in May for two Pembrokeshire double murders in the 1980s.
And Ronald Steven Toms was jailed in June for a sex attack in Ammanford in 1987.
One case under review is an attempted rape and burglary in Hanover Court, Milford Haven, early on the morning of Sunday 6 February 1994.
Det Chief Insp Andy Williams said: "We do have new evidence but we still need the public's help to solve this crime.
"We are asking for anyone who may have suspicions about who did this crime or anyone with information to contact us.
"Sadly, the victim has passed away but we are continuing to pursue the individual who put her through a horrific ordeal."
