An anonymous letter was sent to each member of the Board of a public company that viciously disparaged the CEO and criticized the company’s distribution methods as well as supplier and customer relations. The letter cited operational details that could only be known to a person from within the company. Fearful that the critical information in the letter might be made public and circulated to suppliers and customers, with the potential of adversely affecting product distribution and share price, the company launched an investigation and hired Stroz Friedberg to identify the anonymous writer. After analyzing the content of the letter using proprietary software that assists in the evaluation of the psychological state, characteristics and anti-social risks presented by specific communications and with expert assistance from a behavioral psychologist, a profile of the anonymous author was developed and a suspect pool of insiders was identified. The e-mail and other writings of the suspects were then compared to the anonymous letter writer, resulting not only in his identification but also a method for managing his relationship with the company to mitigate the risk of further harm.
