A coroner is seeking to trace relatives of serial killer Robert Black to ask if they want to participate in his inquest.
Scottish-born Black, who was convicted of four child murders but suspected of many more, died of heart disease in a Northern Ireland prison in 2016 aged 68.
The loner paedophile from Falkirk was a delivery driver who stalked the roads of the UK searching for victims.
Coroner Patrick McGurgan said relatives should be offered the chance to give evidence. He was speaking at a preliminary hearing today in Belfast ahead of his inquest later this year.
“I think all efforts need to be made to trace the next of kin,” he said.
A lawyer for the Coroners Service said he believed some relations may live in Northern Ireland.
Mr McGurgan suggested lawyers who represented Black in trials prior to his death might be able to help trace relatives.
“I think it’s important that the family are given every opportunity to participate fully in this inquest,” he said.
Black was cremated and his ashes were scattered at sea after prison authorities in Northern Ireland revealed no-one wanted his remains.
The killer’s long reign of terror was ended in 1990 when he was caught red handed by police with a barely alive six-year-old girl hooded, bound, gagged and stuffed in a sleeping bag in the back of his van in the Scottish village of Stow.
He had sexually assaulted her moments earlier.
Once in custody, the predator was linked to a series of unsolved crimes from the previous decade.
In 1994, Black was found guilty of three child murders in the 1980s – those of 11-year-old Susan Maxwell, from the Scottish Borders, five-year-old Caroline Hogg, from Edinburgh, and Sarah Harper, 10, from Morley, near Leeds.
He was also convicted over a failed abduction bid in Nottingham in 1988.
In 2011, Black was found guilty of the 1981 murder of nine-year-old Jennifer Cardy, from Ballinderry in County Antrim.
Black, who lived out his last days in Maghaberry high security prison in Northern Ireland, was also suspected of involvement in other killings and unexplained disappearances.
He has long been the prime suspect in the case of missing 13-year-old Genette Tate, who was last seen in a rural lane in Aylesbeare, Devon, in 1978.
The killer was put up to be fostered within weeks of his birth in 1947.
A couple from Kinlochleven in the West Highlands, who took him in, both died within 11 years.
Black spent the rest of his childhood in residential homes in Falkirk and Edinburgh.
