For more specific searches, professional investigators can use the Black Book Online at www.crimetime.com/online.htm. This site provides reports from telephone directories, reverse telephone number searches, business and real estate records, news archives, death and criminal records, professional licenses, bank accounts, and other sources.
Next to terrorism and domestic security, the most ubiquitous concern in investigations is probably identity theft. If you suspect that someone may be using a stolen identity of a deceased person, www.ancestry.com will verify the Social Security number of the true holder. There are also a variety of other sites that make great resources for tracking down antisocial butterflies of all stripes and sizes.
For example, AutoTrack Plus (www.dbt.com) from Database Technologies provides per-minute pricing for access to a variety of sources. With just a name, you can obtain a subject's current and past addresses, telephone numbers, Social Security number, date of birth, and information regarding neighbors and friends. While the source of the information is not always apparent and AutoTrack does not provide direct links to civil and criminal databases, this is an excellent starting point for any identity search.
Sgt. Andre' BeLotto of the Los Angeles Police Department says he finds Accurint (www.accurint.com) a very valuable resource despite its pay-per-search requirement. BeLotto says the cost is negligible, considering the quality of the information. However, he notes that the data can be 30 to 60 days behind.
Even so, Belotto says the Accurint site saves him time and legwork on investigations and spares him from pursuing blind alleys and dead-end leads. For county, state, and federal court histories, the charge per report ranges from $12.50 to $44, although not all states are available. You can also find individual and business searches, comprehensive address reports, bankruptcies, motor vehicle and boat registrations, property, and other asset records.
