Spoiler for ep12:

Kei-chan pre dug the first hole during the day and he seemed to have finished in the evening, where he possible could have gone to the festival.

Also since he dug 2 holes he might actually have burried the corpse in the other hole. Right now I do think that Tippei is dead and everyone that says he was at the festival is just lying. I think Rena, Mion and Rika knows/suspects that Kai-chan killed Tippei.
"There's a possibility that sudden drowsiness will cause an outburst of mistrust and derangement." That sounds abit like syringe scene in ep.4.
