I don't think RF told CE the real deal. I think CE got some misogynistic version to up the chances he'd help. "She didn't return my affection so I strangled her," doesn't really move my heartstrings.
Im leaning towards, 'she overdosed while I was at Dairy Queen'.
Had he raged out and killed her... why call a friend for advice afterward?
That's a solo fk-up and a solo cleanup.
She od'ed/killed herself....there's too many holes in that story already.
If he says she died while he was at DQ (3 or 4am)... why did he call CE at 3a?
And, if he had called to say she freaked out and od'ed or killed herself... CE would have said, "Call 911." Not, "yeah, that's gonna look suspicious, I'll help you bury her later." CE might be a sociopath/narcissist/idiot...but I'm giving him enough credit to not step in any avoidable shat (initial shat)..
The eagerness of CE to help RF (and how quickly RF called CE) spells a mutual interest/guilt at stake.
Hmm...how about drugs?
As in drug use, manufacturing, transportation and/or sales.
In this situation, Rohypinol or similar. Either RF got it from CE or RF supplied it to CE. And it most likely wasn't the first time.
RF was able to get his help by convincing CE he would be in big trouble for supplying the pills - or by instilling fear in him that he would be exposed for using roofies on girls.
I wouldn't be surprised if there is a big seedy back story of these two keeping score and comparing notes on the girls they've drugged. I don't know much about RF other than recent gossip. CE, on the other hand, has always raised my guard.
