The family of Jean McConville have said they are shattered but not surprised there will be no new prosecutions.
But, Michael McConville, who was present the night his mother was snatched from her home in the Divis area of west Belfast in 1972, has vowed not to give up the fight for justice.
He said: "We are shattered by news of it but we really knew what the outcome was going to be.
"We just hoping new information comes in.
"We know there are people out there with information about my mother's case and we would like them to come forward and help us."
Mrs McConville, a widowed mother-of-10, was among 16 people abducted, killed and secretly buried by republican paramilitaries during the Troubles.
Ostracised by the community amid false claims their mother was an informant, the 10 siblings were split up and put into separate care homes across Northern Ireland.
Michael McConville, who is still haunted by the disturbing images of his screaming mother being ripped from the clutches of her children by a gang of masked men, believes the kidnappers should be tried at the International Criminal Court in The Hague.
He added: "I remember a rap coming to the door and I remember one of my brothers or sisters answering it. A lot of people came into the house - there were four women. These four women had not got masks on.
"They told us they were only taking our mother away for a short time but that wasn't the case.
"They denied, even after, that they had taken my mother away. They denied it right up until 1995.
"Then they came out in 1995 and said they took my mother, Jean McConville, away and took her to a beach and murdered her and put her into a grave.
"I don't think these people should be even tried here (Northern Ireland).
"They should be tried in the Hague for war crimes because that's what it was.
"My mother was in her own home when these people came in and took her out of it. They took her down to a beach and shot her.
"They had her arms and legs tied up and then they secretly buried her.
"This has happened in Europe before and the people that did it were brought to The Hague for war crimes. What is the difference with our mother's case?"
