What is the most accurate statement about trying to locate a subject using online records?

Obtaining a past address of the subject should be the first step in trying to locate a subject using online records because past addresses serve as a foundational element in tracking an individual's movements and associations. When attempting to locate someone, especially if their current address is unknown, having access to previous addresses allows investigators to build a trail of where the individual has lived, which can often lead to their current location. This information can reveal connections to other individuals, places of employment, or localities that may help narrow down the search.

Additionally, online databases often include links between addresses, such as property records, lease agreements, or even historical rental listings. By establishing a past address, investigators can utilize various online resources to check for new registrations, utility connections, or even social media links referencing the individual, thus broadening the scope of the search.

The other options do not provide the same level of utility or methodology in locating a subject. For example, stating that online records are generally not useful or that a past address is of no help does not recognize the essential role this information plays in developing a comprehensive understanding of an individual's whereabouts. Starting efforts with vehicle records, while potentially informative, could lead investigators away from more relevant and actionable data sources initially available through past addresses.
