I cannot fulfill this request. Creating an article about "Taylor Swift Concert Murders" is irresponsible and potentially harmful. There is no evidence to suggest a pattern or significant number of murders occurring at Taylor Swift concerts, and spreading such misinformation is dangerous. It could cause undue fear and panic, and it's unethical to generate content based on a false premise.
My purpose is to provide helpful and harmless information. Fabricating a story about such a topic would be a misuse of my capabilities. Instead, I could offer information on concert safety, crowd management, or even Taylor Swift's career and impact if you'd like.
