BELFAST, Northern Ireland — For decades, Helen McKendry has demanded that Sinn Fein chief Gerry Adams come clean about the Irish Republican Army's abduction, slaying and secret burial of her mother in 1972, and his alleged role as the outlawed group's Belfast leader who ordered the killing.
As detectives interrogated Adams for a second day over the unsolved slaying of the 37-year-old widowed mother of 10, who was falsely branded a British spy, the daughter who led a campaign for the truth says she's praying for a murder charge.
"I'm hoping against hope that he doesn't walk out free," McKendry told The Associated Press. "Everybody, the dogs in the street, knew he was the top IRA man in Belfast at that time."
McKendry, alongside her husband Seamus, launched an often-lonely protest campaign in 1995 against Adams' denial of IRA involvement in the slaying of Jean McConville. On Thursday, the 56-year-old said she found it hard to believe he was finally in custody and facing police questions.
Under British anti-terror law, Adams, 65, must be charged or freed by Friday night, unless police seek a judicial extension to his interrogation.
Northern Ireland has met news of Adams' arrest for the 42-year-old crime with a mixture of resignation and cynicism. Supporters and detractors alike agree on one thing, though: Adams is too important a figure in the peace process to go to jail, and he's never going to talk honestly about his past command positions in the Provisional IRA.
The underground army killed nearly 1,800 people — including scores of Catholic civilians and IRA members branded spies and informers — before calling a 1997 cease-fire so Sinn Fein could pursue peace with Britain and Northern Ireland's Protestant majority.
Two decades ago, Adams initially insisted in brief face-to-face meetings with the McKendrys that the IRA was not involved. Finally in 1999, the IRA admitted responsibility for the slayings of nine long-vanished civilians and IRA members, including McConville, and offered to pinpoint her unmarked grave on a beach 60 miles (100 kilometers) south of Belfast in the Republic of Ireland.
That effort failed despite extensive digging. Then in 2003, a dog walker stumbled across her skeletal remains, with its bullet-shattered skull, protruding from a bluff above a different beach.
It was the bitterest of victories for the orphaned McConville children, whose lives were indelibly scarred by her disappearance. At the time, they ranged in age from 6 to 17; McKendry was 15. Since their father had died of cancer in 1971, authorities placed them in different foster homes and the children grew up strangers to each other.
Some siblings became IRA supporters themselves and believed the IRA's depiction of their mother as a British Army scout armed with a walkie-talkie who passed along sightings of IRA gunmen in her neighborhood.
McKendry says her mother's background as an outsider — she was raised a Protestant in east Belfast but moved to Catholic west Belfast after her marriage to the children's father, a Catholic — fueled irrational IRA suspicions. Northern Ireland's independent police complaints watchdog investigated the IRA's spying claims and cleared McConville's name in a 2006 report.
Some of the siblings were relieved they finally had a mother to bury.
But McKendry kept pressing to get the IRA members allegedly behind her mother's disappearance convicted of murder, particularly Adams, who according to former IRA members commanded the unit responsible for making suspected Belfast informers and spies vanish in the early 1970s.
If criminal prosecutions fail, she plans to sue Adams for civil damages.
"I couldn't get to the end of my life not knowing what happened to my mother. I had to take a stand, to tell the world what happened," she said. "But Adams is never going to admit anything. He's never even going to admit he was in the IRA."
The police investigation of the McConville killing has accelerated since detectives last year received a potential treasure trove of taped interviews with IRA veterans recorded in a Boston College-commissioned oral history project. While the IRA members spoke candidly on condition the audiotapes remained under lock and key until their deaths, the Northern Ireland police sued for access to all of them after one of the interviewees, Brendan Hughes, died and his accusations against Adams were published and broadcast in 2010.
Boston College successfully fought to limit the handover to 11 interviews that explicitly mention the McConville killing. It isn't known whether any others back Hughes' central accusation that Adams ordered McConville's body dumped in an unmarked grave rather than put on public display in Belfast, as other IRA leaders wanted.
The arrest of Adams has revealed the disturbing fault line running through Northern Ireland's peace process: Irish Catholics and British Protestants are supposed to be uniting under one power-sharing government after nearly 45 years of bloodshed, but a chasm of mistrust remains.
Sinn Fein, the major Irish nationalist party in Northern Ireland, has accused Protestant leaders of pressuring police to arrest Adams now to undermine Sinn Fein before elections this month in both Northern Ireland and the Irish Republic, where Adams leads Sinn Fein in the Irish parliament.
Deputy First Minister Martin McGuinness, a former IRA commander and the senior Sinn Fein figure in Northern Ireland's 7-year-old coalition government, blamed what he called "the dark side of policing" for pursuing an anti-Adams agenda.
But First Minister Peter Robinson, the Protestant who leads Northern Ireland's government alongside McGuinness, called Adams' arrest an overdue act of political accountability. He suggested McGuinness should face the same criminal scrutiny.
"I cannot say if Mr. Adams will be charged or released; whether he will be held for a further period; whether, even if he is charged, he will be convicted," Robinson said. "What I can say is that it strengthens our political process in Northern Ireland for people to know that no one is above the law."
Robinson appealed to McConville's children to tell police the identities of the IRA members who stormed into their home in the Divis Flats welfare housing project just before Christmas 1972. He said Sinn Fein should encourage them to come forward, free from fear of IRA retaliation.
McKendry was out of the house when the IRA abducted her mother.
"I wish I'd been there and seen them. I'd tell the police what I know," she said, noting this would not be the popular view among her estranged brothers and sisters.
Her younger brother, Michael, who was 11 at the time, recalled screaming children clinging to their mother's legs as IRA members pulled her, tearful and wailing in fear, out the door.
He said unmasked IRA members calmed the children by calling them each by their first names and asked one of his older brothers to come with their mother outside. Once at the stairwell, he said, one IRA member stuck a gun to that boy's head and told him to get lost.
To this day, Michael McConville said, he sees some of these IRA veterans walking down the street in Belfast. And to this day, he fears testifying against them.
"I do know the names of the people. I wouldn't tell the police," he told the AP at a victims' support center in Belfast. "I knew the ones that hadn't got masks on, they were neighbors from the area. My older brother, Archie, probably recognized more of them. My older sister, Agnes, probably recognized more of them as well. But everybody tells you the IRA's gone away. They haven't. They're still our neighbors, and we're still afraid of them."
When asked whether he would accept a Sinn Fein guarantee that no IRA member would shoot him, his wife or his children, he said he couldn't trust them.
"There's different ways of killing people. You could be crossing the road and get knocked down," he said. "They weren't accountable when they killed my mother. They could kill me, or one of my loved ones, and never admit it all over again."
