The Thirty-Day Clock: What Disappears From a Crash Scene Before Discovery Opens
Most personal injury cases in Wisconsin are not lost at trial. They are lost in the first month, quietly, while everyone is waiting for the police report.
I have worked crash and injury scenes for criminal defense attorneys for years, and the pattern is the same on the plaintiff side. By the time a file gets to discovery, the evidence that would have settled the case at policy limits is gone. Not hidden. Gone.
Start with video. Nearly every intersection in Milwaukee County is covered by something: a gas-station camera, a bar's back door, a doorbell across the street, a city traffic camera, a bus. Almost none of it is kept for more than seven to thirty days. A preservation letter mailed in week three arrives after the drive has already overwritten itself. The only thing that works is a person walking the block in the first week, asking who has a camera, and getting the footage or a preservation letter into the manager's hand that day.
Then the witnesses. The crash report lists the people who stayed. It does not list the woman in the second car back who left before the officer arrived, or the clerk who watched through the window. Both of them will remember the light, the speed and the phone in the driver's hand, this month. In six months they will remember that there was a crash. A notarized statement taken in the first two weeks becomes an exhibit. A phone call in month five becomes a maybe.
Then the scene itself. Skid marks fade in days. Gouge marks and debris are swept. A broken sign or a missing stop bar gets repaired, and with it goes your evidence that the intersection was defective. Sightlines change with the season: a hedge that hid the stop sign in June is bare in November. Photographs with measurements, taken in the same conditions as the crash, are the difference between an argument and a diagram.
And the defendant. Prior crashes, prior citations, a suspended license, a business that has been sued four times, a policy that is smaller than the injuries. All of it is available in the first month and all of it changes how you value and plead the case. Waiting for the carrier to tell you what the policy limits are is not an investigation.
None of this is complicated. It is a matter of someone going, in person, before the clock runs out. That is what I do, on the plaintiff side only, with a written report you can attach to the demand. If you have a crash report on your desk from the last two weeks, send it over today.
