The FSS 's innovative and highly sensitive DNA profiling technique called LCN ( low copy number ) was used in convicting Antoni Imiela ( the M25 rapist ) and Ronald Castree ( for the murder of Lesley Molseed in 1975 ) , but was questioned during the 2007 trial of a suspect in the Omagh bombing . However , a review by the CPS found that " the CPS has not seen anything to suggest that any current problems exist with LCN . Accordingly we conclude that LCN DNA analysis provided by the FSS should remain available as potentially admissible evidence " . In addition , other Police Forces around the world are reviewing cases where LCN DNA profiling resulted in the successful prosecution of suspects . Included in this are several high-profile international cases including the murder of Swedish Foreign Minister Anna Lindh by Mijailo Mijailovic and in Australia , the murder of a backpacker Peter Falconio by Bradley Murdoch
