If an Offender's Computer Reveals a Large Number of Contacts

If an offender's computer reveals a large number of contacts, a good solution is:

A) To pass the contact information to local departments and have them contact the individuals in person
B) To draft a simple form letter summarizing the investigation and listing the suspects' online nicknames and e-mail addresses, and request assistance
C) To reach out to each contact, using the offender's computer and online personas
D) To determine what schools the contacts attend and have their principals call the students and their parents in for consultation
