To verify that a wanted person's entry is still valid, what is the best source to check?

To verify that a wanted person's entry is still valid, checking with the courts is the best source. The courts maintain the official records regarding active warrants, including their current status. This ensures that the information is accurate and up-to-date regarding judicial decisions or new developments that may affect the warrant's validity, such as a recent dismissal or a change in the case status.

While local police departments and state criminal databases can also provide valuable information, they may not always reflect the latest changes made by the courts. Local police departments may only have local warrants and may not have access to all information from the courts. State criminal databases are useful but might not have real-time updates or could vary from jurisdiction to jurisdiction in how they reflect court actions. Your agency’s TAC (Technical Assistance Center) might help in accessing databases or providing general assistance, but it doesn't hold primary data concerning the validity of warrants like the courts do. Therefore, for the most definitive and reliable verification, the courts are the primary point of contact.
