How do you research a cold case when the public record is thin?

I’d build a timeline first, and mark each detail by where it comes from and how certain it is. A newspaper report, an official record, and a later retelling aren’t interchangeable. If dates conflict, keep the conflict visible instead of quietly picking one version.

Be especially careful with rumors about people who might have been involved. Repeating a name or theory can cause real harm, and a thin record doesn’t make speculation stronger. It’s fine to say the available information doesn’t establish who was responsible.

Try looking for records that could clarify the basic timeline, such as contemporary local news coverage or official death and investigative records, where access is permitted. Keep notes on what you checked, including searches that turned up nothing. That makes the limits of the research clearer.
