The daughter of the man known as the BTK serial killer is speaking out about how her father is earning money from prison. On social media, Kerri Rawson says her father is sending letters, art, and prison clothing to a third party who sells it to a memorabilia company. Rawson says this is illegal and yet making it through the prison’s mail room.

Rawson says, “It appears as for at least the last four years that I know of, my dad has a financial racket going on in prison. He sends letters, art and now apparently prison clothing to a third party, they sale it to a murder memorabilia website and he gets a cut.

This is against the law and somehow these larger items are making it through the prison mail room.
