Detectives have identified a married couple who were the witnesses at the Brighton wedding of serial killer Peter Tobin.
They were identified after an appeal on the BBC TV programme Crimewatch.
Detective Superintendent David Swindle is leading the investigation into Tobin’s past.
On Crimewatch last Wednesday he appealed to the public to help him find three people who had met Tobin in the past.
The three included a married couple who were the only official witnesses to Tobin’s first marriage in Brighton in 1969.
The appeal was successful and the couple named on the marriage certificate have been traced.
Detective Superintendent Swindle said: “The response from the public has again been extremely positive, and through Crimewatch and subsequent media appeals we received a large number of calls from people determined to help us piece together the missing gaps in Peter Tobin’s life.
“We are delighted to have traced the couple named on Tobin’s marriage certificate and they will now form part of our inquiry.
“At this stage it is too early to say if they hold any information that could be of assistance, but time will tell.
“I would like to take this opportunity to thank the public and the media for their continued support in this complex investigation and encourage anyone with information on Peter Tobin or his movements over the years to contact Crimestoppers anonymously on 0800 555111 or email operation.anagram@strathclyde.pnn.police.uk.”
