CASE SOLVED!
Enough details have been uncovered and brought into connection to declare this case as solved. Please wait a bit for
post-game summary.The woman was a cult leader. They believed it was the end of the world. The means they were to commit suicide didn't kill the woman, and when she woke up the next day, the world was intact and beautiful, the subjects were dead. Unable to handle the guilt, she killed herself.
YES Except for one detail, but this way works as well.The woman was the leader of a cult and had prophesized the end of the world for that night.
Most of the cult's members, including her kids, had taken poison so as not to have to experience the end of the world.
The woman herself wanted to face the terrible event and dismissed the poison.
When she realized that she had been wrong the next morning, she killed herself as well.
Hoho, it seems that one was a bit harder than expected, but you all did a good job solving it.
Though, looking at it now, finding the detail of a cult is pretty hard.
I will take a little break with the riddles again, so no new one will be up before tomorrow night.
