San Marino is a residential community with regular commuter traffic and frequent pedestrian activity. That means many DUI cases turn on details like:
- Timing and lighting (evening visibility changes can affect how officers describe driving behavior)
- Nearby cameras (doorbell systems, home security footage, and traffic-area cameras may capture the moments before impact)
- School/park-area activity (witnesses may be nearby and may remember key movements)
- Road design and turning points (where a car entered a lane, made a turn, or failed to stop)
In DUI cases, small inconsistencies—like when a witness saw the vehicle or how officers characterized lane position—can matter. That’s why early organization and evidence preservation are so important.
