Most records that matter in Jefferson County are kept at the county level: court files with the clerk, and deeds with the county recorder or register of deeds. 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.
Can an investigation in Festus extend to Crystal City or Herculaneum?
Yes. People rarely stay inside municipal lines. Work that starts in Festus can continue in nearby communities such as Crystal City, Herculaneum, Pevely, planned as one engagement and carried out by detectives licensed for each place the work goes.
Can I record a phone call in Missouri?
Missouri generally allows a participant to record a phone call (one-party consent), unless it's done with criminal or tortious intent. Recording a conversation you're not part of is generally illegal. This is general information, not legal advice.
