public Student investigateCrime(Fingerprint x)

Oh, heck, there's a crime! and the fingerprint is x. So lets ask around. Check with 4 different Citizens. Ask each if they know anybody with the given fingerprint. If they do, then return that student as the prime suspect. Otherwise, ask until you have checked with 4 students.
