All 7 suspects had trackers placed on them and all 7 were in different places.

One of these statements is true

1) BP is alive and is RJ as he is the only suspect tracked to that location
or
2) RJ gave his phone to someone else, (accomplice) and killed BP he would not be able to do this without someone's help from the team thus knowing where BP was. So one of the 3 is definitely involved
or
3) RJ is not on the list of 7 and is someone else.
