crimelite fluorescence solves caseA criminal investigation into the murder of two teenage girls that took place almost 40 years ago has finally been closed following the re-examination of evidence using modern Crime-lite forensic light sources.

Known as the World’s End Murders, the horrific murders of Helen Scott and Christine Eadie, in Edinburgh, in October 1977, remained unsolved for decades despite thousands of interviews and many hours of police detective work.

Despite the passing of years, the case remained in the public conciousness and investigators never gave up hope of unravelling the brutal crimes.

During a cold-case review conducted between 2011 and 2012, the vital breakthrough was made when evidence from the case that had been kept in storage was re-examined using Foster + Freeman Crime-lites.

Under the intense narrow-band illumination of a Crime-lite, forensic examiners were able locate previously undetectable traces of semen and saliva. The new evidence provided a direct DNA link between the prime suspect, Angus Sinclair, and the murdered girls.

Using evidence uncovered using the Crime-lite, prosecutors were able to take the case back to court where it was successfully argued that the case be re-heard (Scotland’s first ever double jeopardy case). In November 2014, Angus Sinclair was jailed for life with a minimum of 37 years behind bars.

Lord Advocate Frank Mulholland, the most senior Law Officer in Scotland, later said of the Crime-lite, “without Crime-lite, there would have been no trial”. So impressed was he with the technology that he recommended the light sources be introduced to all Scottish forensic labs.
