First, a private investigator will discuss your case and understand what you’re trying to discover.

Next, a private investigator will start tracking and monitoring the subject’s activities. The PI will discreetly watch the subject and record all the observations in a detailed report along with photographic and video evidence. Private investigators may also track by attaching a GPS device to the subject’s vehicle.

Once adequate evidence has been collected, it will be presented to you. You can decide whether it is enough to prove your suspicions.
