Has Lindy Benstead's killer been found?
Nobody has ever been charged with the deaths of Lindy Benstead or Peter Thurgood.
At the time of the murders, Lindy's husband Mick was questioned but had a clear alibi.
The police were unable to tell if the attack had been motivated by the affair or not.
One line of investigation led the police out to America but they were unable to corroborate evidence.
Without new evidence or a confession, it is unlikely this case will be solved as much needed forensic evidence is missing.
A joint statement from both the Thurgood and Benstead families said: "These terrible killings of our loved ones have haunted both families for 35 years now, and we remain united in our desire to support any enquiries that will help bring justice and closure for us all.
"We ask anyone who has any information they have not yet brought to the police, to come forward now."
Police released drone footage in hopes of bringing forward new witnesses and evidence.
Sussex police Detective Superintendent Emma Heater said: "At the time of these tragic murders and since, numerous people have been named as allegedly being involved and two arrests were made.
"All these leads were thoroughly explored but have not led to any further developments or arrests.
"There remain ongoing forensic enquiries, and further items are currently undergoing examination using techniques developed since 1986.
"We remain in contact with both families and they will be updated with any significant developments.
