THE family of Jean McConville insist that their fight for justice will go on following the release without charge of Sinn Féin leader Gerry Adams.
Mr Adams was released last night having been questioned for four days by PSNI officers in Co Antrim over the 1972 killing of the mother-of-10.
Upon his release he claimed there was a "sustained, malicious, untruthful campaign" against him.
Jean McConville, a 37-year-old widow, was abducted from her Belfast home, shot and secretly buried. Her body was found on a beach in County Louth in 2003.
As Mr Adams was released, Michael McConville said his family would continue to fight "to the bitter end" for justice for their mother.
"These have been quite difficult days for the McConville family and they have been very stressful.
“We would like the people to know that the family is going to stay to the bitter end until we get justice for our mother,” he added.
"We know it is going to be a long road, but we have already been fighting for justice for 40 odd years and we are not going to stop now."
Mr Adams, former MP for West Belfast and current Dáil representative for Co Louth, presented himself for interview by prior arrangement with detectives on Wednesday night.
He was then arrested under the terrorism act for questioning about the IRA murder of Mrs McConville.
He was freed at 8pm last night. Police said a file would be sent to the Public Prosecution Service.
Jean McConville was murdered in 1972Speaking at a news conference in Belfast following his release, Mr Adams said he had contacted the PSNI two months ago about the McConville case.
He questioned the timing of his arrest in the middle of an election campaign and claimed they could have used discretion rather than "pernicious, coercive legislation" to deal with the matter.
The Sinn Féin leader said that while he was in custody police carried out 33 taped interviews with him and showed him old photographs of himself and Deputy First Minister Martin McGuinness.
He also said that he was presented with interviews conducted by people who were "enemies of the peace process". These are believed to be tapes of interviews ex-IRA men and women gave to researchers at Boston College in the US.
Mr Adams repeated his insistence that he is innocent of any involvement in Jean McConville's murder.
He added that Sinn Féin remained fully committed to the political process in Northern Ireland and reiterated his support for the peace process.
"The IRA is gone, it's finished," he said. "I want to make it clear that I support the PSNI."
Prosecution lawyers will now decide if there is enough evidence to bring any charges against Mr Adams and what those charges would be.
It is thought that police want to charge Mr Adams with IRA membership.
Mrs McConville is one of The Disappeared, a number of people who were abducted, murdered and buried in secret by the IRA during the Troubles.
She was kidnapped from her home in Divis Flats in west Belfast in front of her children after being wrongly accused of being an informer to the British Army.
Last month, Ivor Bell, 77, a leader in the Provisional IRA in the 1970s, was charged with aiding and abetting the murder, and there have also been a number of other arrests recently.
