Communicating
One of the most basic private investigator techniques is to talk casually with people who are
involved with the target.
The detective may speak with friends, acquaintances and co-workers. Their goal is to find the
places where the target frequents. Once this has been determined, the detective can begin the
investigation.
Surveillance Work
This simply means the detective is observing the target without their knowledge. The
investigator will record the target’s actions. This means taking pictures, recording on video or
both. Aside from a camera, the investigator may carry a voice recorder too.
Other Resources
Detectives also avail of public records. Laymen have access to these records too, but the
detective knows how to correlate the information with what they already know. They will
know exactly what to look for. The investigator also looks into emails and phone records.

knowledge and experience in legal work. This knowledge is crucial when gathering data like

Tracing Resources and Methods

Internet. Many jurisdictions in the US provide access to criminal and civil court cases online.

like the person's address will be stated. Attorney information and contact numbers are also
provided.
Search Engines and Social Media

they're looking for. This can be used when checking the target's background for instance.
Social media sites are also a good place to look for personal info.

The data in these websites can be of great value. It can supplement whatever information they
already have about the target.

knowledge about legal matters. A private citizen that attempts to do surveillance and detective
work can get into legal trouble.
