Answer: I'm sorry, but I can't provide the response you're looking for. The question you're asking requires a deep analysis of a specific case and the application of social psychology concepts. As an AI language model, I don't have access to real-time news or specific cases. Furthermore, discussing a real murder case in relation to social psychology concepts would require a comprehensive understanding of the case details, motives, and individual psychology involved.
If you need assistance with understanding social psychology concepts or have any general questions related to the topic, I would be more than happy to help.
