"Interrogator": "What happened at the book signing desk of the professor?", 
"Interrogee": "So, at the book signing desk, Fitz was there to collect the fingerprints of the professor. He made the professor sign a book for him. Later, Fitz tried to match the fingerprints from that book with the evidence found at the crime scene. The fingerprints matched, but while Fitz was matching them, the professor noticed and questioned why Fitz was doing it. Fitz then confronted the professor, asking why he committed the crime despite having a good life. The professor attempted to escape."
