How We Begin Your Search
Start with the person’s name, approximate age, last known location and the date of your last contact. Photographs, known addresses and other background details can help us assess the assignment. Limited information does not necessarily prevent a search; we will discuss what can realistically be done.
Our investigators may use records research, phone work, interviews and field inquiries as appropriate. We evaluate leads and keep the investigation focused on your objectives. Results and timing depend on the circumstances and the information available.
