Ferguson residents know the area is shaped by commuting routes, intersections, and high-speed merging patterns common to St. Louis County. When a fatal crash happens—especially near busy corridors—key evidence can disappear quickly:
- Dashcam and traffic video may be overwritten or lost unless requested promptly.
- Witnesses often provide inconsistent details if contacted late or if statements are taken informally.
- Vehicle data (including event data recorders) may require technical steps to preserve.
That matters because an AI tool can’t request police reports, obtain preservation orders, or evaluate whether the facts support causation. Your best “calculator” is a case file built early enough to be usable.
