The core memory had been wiped quite well before being physically removed to prevent further data loss. What remained was encrypted and fragmented. Breaking the encryption was difficult, requiring a lot of time and work.
Most of the decrypted data was useless information. The only thing worth following up was reference to Silvia. The professor’s daughter’s name as well as the name of the elderly couple’s granddaughter. An odd coincidence and that they are both spelled with an “i” instead of a “y” in the name, “Silvia,” instead of, “Sylvia.”
