Sorry have to jump in. I think you missed the point as well. I do not think you were asked to prove anything. Just merely state what you 'think' happened. I think we can all agree that you were not there to witness anything.
IMO it is A POSSIBILITY that someone else surfaced and Christina ended up going off with one of them.
I suspect either CM or EA received a phone call from somebody. At that time, EA headed back to SOL to meet up with another man.
Without access to all phone pings and records, alibis, and the circumstances surrounding an alleged altercation (or threat of one) between HF and ALP, it is impossible to connect the dots (or rule out involvement).
LE hasn't explained the evidence they believe they have from EA's Camaro. Until the evidence is presented or until EA is charged with murder (even then I still want to hear the case), I can't dismiss another person being involved (who had greater motive to harm Christina).
EA is an accomplice at the very least, or he acted alone.
Furthermore, if drug dealing is tangled up among members within the group, and CM was used over boundary or other wars, it may explain why no one is talking. Everyone fears they could be targeted next.
In recent program I watched (can't recall which one), an Investigator explained people have been killed over a small amount of pot. No joke.
We know for a fact drugs are part of HF's world and, we've heard, CM wasn't too pleased.
He was on probation at the time she disappeared. Therefore, she must have been aware of his troubles.
My fear is HF crossed over to the big league.
He may have been a small fish but, in a big league, it doesn't matter. Did he have debts to pay?
