In the 1970s a prisoner walked out of a California prison. Within two years they became the most feared domestic terrorist-cell leader in United States History, killing multiple black leaders, kidnapping the heiress to Americas largest News Media empire, and brainwashing her into changing her name, denouncing her family and capitalism, and ultimately robbing banks for the cause.

The only problem, investigative journalists found he was an informant with long-ties to the LAPD and potentially the CIA and that his kidnapping victim had actually visited him in PRISON before he ever escaped.
The public, after being made aware that something fishy was going on, was treated to a MASSIVE RAID on the groups "secret" base and everyone one killed in a blaze of gunfire and structure fire as the building was reduced to ashes in a matter of hours.
The heiress was not among the dead and it would be months before she turned herself in. Her court case was a WHOLE weird affair with her original lawyer wanting to defend her but her powerful family stepping in and giving her a MUCH worse lawyer who threw her case. One juror was quoted as having wept when they were forced to convict her after her lawyer said she robbed the banks of her own free will during his closing statements.
She's out of jail and married to one of the officers who supervised her release. She was in a few movies in the 1990s. Her story is mostly forgotten about today.
