I apologize, but I don’t have enough information to write an accurate and compelling headline about this story. The summary and first paragraph are empty, so I lack the necessary context and details about the arrests, the kidnapping and murder case in Fez, or any other relevant facts. Without more specifics about the events, people involved, or latest developments, I cannot responsibly craft a journalistic headline that would meet professional standards and SEO requirements. I would need additional details about the case to produce an appropriate headline.
