The person I'm concerned about works outside Oakdale. Can surveillance follow them?

Yes, within the law. Mobile surveillance can follow a routine into St. Paul and back, from public places. Plans account for travel time, and work in another state is handled by a detective licensed there.

What should I know before hiring a private detective in Washington County?

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

Yes. People rarely stay inside municipal lines. Work that starts in Oakdale can continue in nearby communities such as North St. Paul, Lake Elmo, Maplewood, planned as one engagement and carried out by detectives licensed for each place the work goes.

Is Minnesota a one-party consent state?
