The wrong Federal paperwork
When John Haynes wanted to escape from prison, he had a female accomplice impersonate a Federal Marshall, back in 2010.
He was awaiting transportation to a federal prison, when the call came in from a ‘marshal’, demanding that he be released. They told her that they needed the paperwork.
So she called the local Marshal’s Office, and pretended to be an official from the Marshal’s headquarters in Washington and asked for the form. It was obviously denied, and Hayes was given additional time on his sentence.
