Spoiler for spoiler fromHigurashi Kai Episode 5 :

Since i watched this right after ep 5 i did notice something Rena's hat was found in the mountains which lead me to thinking about how it was pointed out that the quary is on the other side of the mountains. could she have been running there or possably taken there

or maybe the people that killed her was some how related to the people in the quary.
One thing made sense when they found them both in the car. Somebody/something might have threatened them and fake the accident
