Both programs involving JWs had the same name: Witness to Murder. This was done intentionally by the producer. I know this to be so since I was involved with the program about the Bryant's for many months.
At the following link is an example of the Bryant story being named Witness to Murder:

Also, on ID Discovery the Bryant program blurb can be located by typing in Robert and Janet Bryant, Deadly Devotion: Witness to Murder. I remember that both JW stories with the same name caused quite a bit of confusion last year. On top of that, the first airing of the Bryant story was August 3rd, which was the first day we in this part of the world watched the Australian Royal Commission Investigation into JW child abuse.
