Start DUI Evidence Preservation With a Timeline
Memory fades fast after an arrest, and receipts get thrown away. DUI evidence preservation begins with a plain timeline written while details are fresh. It should cover where the person was, what they ate and drank, when they drove and what happened at the stop.
Write only what actually happened. Because a timeline that fills gaps with guesses can hurt more than it helps, mark any uncertain time as uncertain.
Records Worth Keeping
Some records disappear on their own schedule. A bar may overwrite camera footage, and a phone may sync and delete files. So gather items early and keep the originals.
- Receipts for food, drinks and rides
- Photos of the stop location, lighting and road markings
- Names and phone numbers of anyone who was present
- Medical records for any injury or condition
- Every paper the officer or jail handed over
Keep each file in its original form. Copies are fine for reading. However, the original carries the date and device details a reviewer may need.
DUI Evidence Preservation for Video
Video often matters most, yet it lasts the shortest time. Store footage from a dashcam or a home doorbell on a second drive without editing it. For footage held by a business, a lawyer can send a written request asking the owner to keep it.
Police video follows a different path. It usually arrives through the court process, which the guide on DUI camera evidence explains.
What Not to Do
Evidence work has limits. Never ask a witness to change a story or to repeat a version someone else wrote. Also never delete messages or posts that look unfavorable, because destroying evidence can create new problems.
Talking about the case online is risky too. Private messages may surface later, so the article on DUI case privacy suggests keeping research and discussion offline where possible.
How Collected Records Are Used
A defense lawyer decides which records matter. Some support a timeline, while others may support a request to exclude evidence. Penal Code section 1538.5 sets the written motion process for asking a court to suppress evidence taken in an unreasonable search or seizure.
Collecting records does not replace legal advice. Instead it gives a lawyer accurate material to review sooner.
Keeping the File Organized
Use one folder for paper and another for digital files. Then add a short index listing each item, its source and the date it was saved.
That index makes DUI evidence preservation useful later. A reviewer can see what exists, what is missing and what still needs a request. The article on DUI arrest paperwork explains the documents most people receive first.
