Private investigators (PIs) use a variety of techniques to find missing persons, blending traditional investigative methods with modern technology. Here are some of the most common methods:

1. Surveillance

• Stakeouts: PIs monitor locations where the missing person might appear, such as their home, workplace, or places they are known to frequent.
• Use of Technology: Surveillance cameras, drones, and other technology can help gather evidence of a missing person’s whereabouts.

2. Public Records Research

• Database Searches: PIs often use online databases to access public records, including birth and death certificates, marriage licenses, real estate transactions, criminal records, and more.
• Social Media: Searching through social media profiles and activity can provide clues about the missing person’s social network, last known location, or intentions.

3. Interviews and Canvassing

• Witness Interviews: PIs talk to friends, family, coworkers, and other acquaintances who might have information about the missing person’s activities, relationships, or emotional state before their disappearance.
