Important Information about Investigations:

Although we are among the best in the industry at what we do and are recognized experts in court, we are not magicians. We cannot make things exist that donít. We cannot find out the employer of an unemployed person. We cannot always find everything our clients would like within a limited scope job.

Accordingly, we do no guarantee any outcome on any case.
