WASHINGTON — As two Islamic State militants faced a judge in Virginia last month, Diane Foley listened from home through a muffled phone connection and strained to make out the voices of the men prosecutors say kidnapped her son before he was murdered.
Alexanda Kotey and El Shafee Elsheikh stand accused of belonging to an IS cell dubbed "the Beatles," an incongruously lighthearted nickname for British citizens blamed for the jailing, torture and murder of Western hostages in Syria.
After geopolitical breakthroughs and stalemates, military actions in Syria and court fights in London, the Justice Department's most significant terrorism prosecution in years was finally underway. For Foley, who months earlier had pleaded with Attorney General William Barr to pursue justice by forswearing the death penalty, the fact the case was proceeding at all felt miraculous.
"We'd met so many blocks over the years, I couldn't believe it was happening," Foley said. "I was in awe of it, really, and almost didn't trust it — a bit incredulous. Is this really happening?"
The prosecution is a counterterrorism success in the waning weeks of the Trump administration. But it almost didn't happen.
Interviews with 11 people connected to the case make clear the hurdles along the way, including a death penalty dispute that required two normally close allies, the U.S. and U.K., to navigate fundamental differences in criminal justice systems. In the end, the interviews show, grieving families reached a gradual consensus to take capital punishment off the table while a key commitment by Barr to do the same enabled the U.S. to obtain crucial evidence it needed.
At another time, the case might not have even been handled in civilian courts. After the Sept. 11 attacks, the Republican-led Justice Department favored detaining foreign fighters at the U.S. base in Guantanamo Bay, Cuba, for military tribunals. But that approach changed. Now federal prosecutors are pursuing the highest-profile terrorism case since trials over the Boston Marathon bombing and Benghazi attack, aiming to secure convictions and punishments that can keep the men, in their 30s, imprisoned for life.
"There was never a time when I thought we didn't have any case," said John Demers, assistant attorney general for national security. But, "we didn't want to bring them here unless we had really good charges, a really strong case, and ultimately expected a conviction that was going to result in a very significant prison sentence."
