On Tuesday, the trio who broke into one of the US government's most secure facilities will learn how long they will have to spend time behind bars.
In 2012, 83-year-old Sister Megan Rice, Michael Walli, 64, and Greg Boertje-Obed, 58, trespassed into the Y-12 National Security complex in Oak Ridge.
The trio defaced a uranium-processing building with human blood and hammers.
Last May, a jury convicted the trio on sabotage charges. Some of their friends gathered at the Church of the Savior in West Knoxville to offer their support.
"We're gathered here as a community to celebrate hope on the eve of the sentencing for the Transform Now Plowshares action," said Ralph Hutchison of the Oak Ridge Environmental Peace Alliance.
But, friends say despite the trio's conviction, their legacies outside of jail will live on forever.
"There's been more attention to this issue here in Oak Ridge than we've seen in the last 20 years probably," Hutchison said.
Rice, Walli and Boertje-Obed were originally supposed to be sentenced last month, but a snow storm delayed that.
Now, the peace activists will go to court once again, each facing anywhere from 6 to 9 years in prison.
WBIR 10News will have full coverage of their sentencing Tuesday.
