A good detective searches those originals rather than relying on online summaries, and confirms identity so records aren't attributed to the wrong person.

Often. Locate work combines records research with field verification, wherever the trail leads. Moves along Interstate 55 and connecting highways are common, and investigations are coordinated across state lines with appropriately licensed detectives.

Yes. Employers can arrange internal investigations, employee theft documentation and injury-claim fact-finding. Work is coordinated with counsel where appropriate and follows employment and privacy law.
