I'm not sure if it's a true story as there could be many fictional or exaggerated accounts with such a title. It might be a very disturbing and tragic claim if it were true, but without proper sources, it's hard to verify.
Jealousy could be a possible factor. Maybe there was envy over the preacher's daughter's seemingly perfect life or the attention she received. Or perhaps there was a conflict over a boy or some other personal matter that got out of hand.
The incident likely led to a lot of fear in the community. Parents would be more protective of their children. There would also be a sense of grief and disbelief. The local community might have held vigils or memorials for the preacher's daughter, and there could be a long - term sense of unease.
Well, it could be related to some sort of mental breakdown. The person might have been dealing with internal issues like depression or paranoia that led them to commit this horrible act. Or perhaps there was a long - standing feud over religious beliefs between them, given that she was the preacher's daughter, and it escalated to this extreme.
Some people might try to make amends in other ways. They could try to do good deeds in the name of their BFF, like donating to causes their BFF cared about or helping the BFF's family. However, the guilt will always be there to some extent, and it's a burden that they will carry for the rest of their lives.
It could be due to a fit of uncontrollable rage perhaps caused by a long - simmering feud over something like money or a romantic interest. Maybe there was a deep - seated jealousy that had been building up for a long time.
The killer should face life imprisonment. Taking someone's life, especially a close friend, is an unforgivable act and they should be removed from society to ensure public safety.
