The news said Keyes is being held at Beaumont Federal Prison. I tried a lookup but came up empty. With the confusion surrounding his name, Keyes Reyes, etc, could it be he's being held under a different name?
From the Federal Prison FAQ"
"I did not get a result for the name submitted with search. What now?
All Federal inmates starting in 1982 are in the Inmate Locator. First, check to make sure you put the information in correctly. Is the name spelled correctly? Is the number correct? Searching for John Doe will not find Jon Doe (the name must be an exact match).
If you still do not get a result, either the person is not a Federal inmate (he/she may be a state or local inmate), or he/she was in the Federal system before 1982."
