In many Helena incidents, the key evidence disappears fast:
- Dashcam and phone video get overwritten or deleted when drivers cycle storage.
- Street surveillance in downtown and near busy corridors may be retained for a limited time.
- Witness recollections fade—particularly when people are trying to get home, to work, or back to family obligations.
- Seasonal driving (winter glare, spring melt, and summer tourism traffic patterns) can affect how collisions are perceived and documented.
When the at-fault driver flees, the case frequently depends on whether the right records are requested and preserved early enough.
