Frankie Richard was considered a person of interest in the cases that spawned the true-crime docu-series Murder in the Bayou.

The documentary will dive further into the mystery than the book does.

Showtime is set to release a five-part documentary series in September about the Jennings Eight murders called "Murder In The Bayou".

If you missed the series, you can watch it online now here.

The death of 8 Jennings women between 2005-2009 will be explored in a 4 part series on the Investigation Discovery Network.
