Good job.
I don't think it's the same guy.
This Brian Miller is paroled in Kennett, MO, which is 476 miles from St. Joseph. Kennett is actually in the Memphis, TN area, and not what you would normally associate with Missouri.

Lannister said that Brian Miller lives in Independence, MO. That is much closer to St. Joseph (66 miles away).
Independence is 436 miles from Kennett.
There's no chance Brian Miller would be assigned to a parole officer in Kennett if he lived in Independence.
To compare, that would be like me committing a crime in Los Angeles, being sent to prison in San Francisco, returning to the Los Angeles area upon being paroled, and having a San Francisco area parole officer. Would never happen that way.
