So I'm solving this crime, and as I was exploring the crime scene, I saw a key name-tagged "Wilbur".
Anyways I went to gather information from the other suspects, and I visited every one of them, asked for "LEADS". None of them told me about Wilbur, and since I don't know his second name, I can't know where does he live.
Is it an error? or does that mean that Wilbur can't be a murderer? Is there a way where I can know his second name, and where does he live?

Thank you very much!!!!

Gotta love those yellow notes!! Look carefully--they are sometimes hard to spot!
