TL; DR: At LA Metro Injury Lawyer, we investigate accident cases by gathering police reports, medical records, photos, video footage, and witness statements — immediately. Evidence disappears fast in Los Angeles, and speed is what wins cases.
Every second after a freeway crash, evidence starts to disappear. Skid marks fade. Camera footage gets deleted. Witnesses leave. The other driver’s insurer starts building their version of events — and it rarely favors you.
When people call us at LA Metro Injury Lawyer and ask, “How do you investigate accident cases?” — Our answer is always the same: fast, thorough, and with everything we have. We gather police reports, medical records, photos, video footage, and witness statements — and we start immediately.
Why Does Speed Win Accident Cases?
In the first 72 hours after a crash on the I-10 or the 405, the scene gets cleaned up, cameras get overwritten, and witnesses move on. Traffic cameras store footage for just 30 to 90 days before it is deleted. The at-fault driver’s insurer sends an adjuster — sometimes before you leave the hospital.
Pre-lawsuit gathering of collision reports, witness statements, 9-1-1 recordings, and surveillance footage is what builds a strong case before anything disappears. That is exactly how we operate. From the first call, we collect data on your injury case and treat your case as if a trial were starting tomorrow.
How Is a Police Report Used as Evidence?
A police report is the first official record of what happened — who was at fault, what road conditions existed, whether citations were issued, and who was present. But police reports are not always accurate. Officers miss details. Insurers use these reports to deny or reduce claims.
We pull the report immediately and check every line. We compare it against photos, physical evidence, and witness statements. If something is wrong, we challenge it. Our practices cover freeway car accidents to multi-vehicle collisions — each requiring a different reading of the same report. The police report is where we start. It is never where we stop.
Is Video Footage the Strongest Accident Evidence?
Ask any trial attorney what they want most in a crash case. The answer is almost always video. It removes the “he said, she said” problem. It shows vehicle speeds, lane positions, and driver behavior in the seconds before impact. A dashcam, a traffic camera, a business security system — any one of these can turn an uncertain case into a clear one.
California courts accept dashcam footage when it is authentic and unaltered. Courts evaluate footage based on relevance, authenticity, and chain of custody — and when those conditions are met, video is often the most persuasive evidence in the room.
We know where cameras are: intersections, businesses, homes, and CHP monitoring systems. We send preservation letters right away and subpoena footage before it is overwritten. When people ask how you investigate accident cases, this is where the answer gets decisive — video waits for no one.
Why Do Medical Records Make or Break Claims?
You get hit on the 110 Freeway. You feel okay. You skip the ER. Three weeks later, you cannot turn your neck — and the insurer says the injury has nothing to do with the crash. That gap in documentation just cost you your case.
Medical records connect your injuries to the accident. Without them, insurers say your pain is pre-existing or exaggerated. With them, we link every diagnosis, every surgery, and every missed workday back to the moment of impact.
We work with your doctors as part of our medical and claim support process to make sure nothing gets understated.
How Do Witness Statements Change Case Outcomes?
Witnesses forget. They move on. And if the other side finds them first, their account might shift in a direction that hurts you.
We find witnesses fast and get their statements on record before memories fade. A driver who saw a truck weaving before the crash. A pedestrian who watched the light sequence. A passenger in a nearby car confirms the speed. Each one adds another layer of proof.
Witness statements support the police report, explain the video footage, and give the full picture a human voice. In wrongful death claims and pedestrian accident cases, where the stakes are highest, eyewitness accounts often shape the outcome.
Is a Lawyer Really Worth It After a Crash?
Yes — by a wide margin. Injury victims with an attorney receive up to three times higher settlements than those who go it alone. Insurers have data and analysts working against you. They know what your case is worth — and they count on you not knowing.
When you work with us, you work directly with Matthew Blair and Oscar Ramirez of Blair & Ramirez LLP — attorneys who have recovered millions for freeway accident victims and know exactly how to investigate accident cases the right way.
Frequently Asked Questions
What is the first thing you do after I call?
We start preserving evidence right away — sending letters to hold footage, requesting police reports, and building your case file before a lawsuit is filed. Time is everything in an accident investigation.
How do you investigate accident cases involving trucks?
Truck cases need more — driver logs, GPS records, maintenance files, and federal trucking regulations. Our truck accident practice is built for this kind of complexity, and we know where to look.
What if I did not file a police report at the scene?
A missing report is a setback, not a dead end. We use medical records, video footage, witness statements, and damage documentation to fill the gaps. Call us as soon as possible.
How long is video footage available after a crash?
Traffic camera footage is usually deleted after 30 to 90 days. Every day you wait raises the risk of losing it. Contact us before it is gone.
Can I still file a claim if the accident was partly my fault?
Yes. California’s pure comparative negligence law lets you recover compensation even when you share some blame. Your percentage of fault reduces your payout — but your right to recover is real.
What types of accidents do you handle?
We handle freeway car accidents, truck accidents, motorcycle accidents, multi-vehicle collisions, pedestrian accidents, and wrongful death claims. If it happened on a Los Angeles freeway, we handle it.
Do I pay anything up front?
Nothing. We work on contingency — no fees unless we win. Start with a free case review.
