Thinking out loud.
BDR is a 31 year old male using an app that is usually played by 12-14 year old children.
BDR has made contact with another player, SLP, a 14 year old female.
BDR began conversing with SLP on Christmas Eve, 12/24/2018.
BDR reads words typed by SLP, she is despondent, being molested, has suicidal thoughts.
BDR convinces SLP that the ONLY way he will help is if SLP captures video of her rape by RP.
SLP unwillingly succumbs to capturing this video On January 10, 2019.
SLP emails this video evidence to BDR.
BDR travels the 700 miles to 'rescue' SLP. Avoiding detection, destroying SLP's cellphones.
BDR decides the evidence would not hold up in court. Does not contact LE, or anyone.
BDR is visited by LE and claims no knowledge of SLP.
BDR is revisited by LE once mom comes home.
SLP is discovered by LE and safely recovered.
Synopsis: LE had information that BDR was totally involved with SLP. From the video file, to the unknown contact (tip) at the St. Louis FBI.
BDR, in denying his involvement, was not trying to protect the victim, SLP.
Jim is a xx year old father/grandfather. He doesn't even know what these APP's are, but he watched over his children during dial-up/AOL/early FB days. He is aware of the dangers out there 'on the Internet.'
He happens to receive a mysterious message, from a person claiming to be in serious trouble. After the heart attack moment, he takes a deep breath. How to prove this is legitimate? First thoughts are asking, "Are you in immediate danger?" "Are you planning to do anything to yourself right now?" "Can you get someplace relatively safe and call me?"
Making a video never even crosses my mind. I'm not contemplating "proof", I'm thinking this person needs help. How can I help them?
BDR had 17 days to figure out how to help SLP. He then had her in his basement lair for 18 additional days. Unless he was going to use that proof, that he coerced SLP into making, there was no chance this was going to end well for SLP.
Mostly IMO with details from CC. (ETA: Not sure if needed)
