Spoliation of Evidence in Injury Cases | Conduit Law

Spoliation of evidence is what happens when proof relevant to your injury case gets destroyed, altered, or hidden — whether on purpose or through careless neglect. It matters because your case is only as strong as the evidence behind it. When the dashcam footage, maintenance logs, or security video that would prove the other side's fault conveniently disappears, you lose the leverage you need to recover. The good news: courts have tools for parties who let evidence vanish, and acting fast to lock down proof is one of the most important things you can do after an injury.

Picture a brutal crash. A semi swerves into your lane on I-70 and your world goes sideways. Your case feels like a slam dunk — you just need the truck's dashcam footage to nail it shut. So a demand letter goes out. Weeks later, the defense lawyer responds with manufactured sympathy: "Regrettably, the requested footage was lost during a routine data purge."

Just like that, the proof is gone. That's spoliation — and it's far more common than it should be.

What Spoliation Actually Is

Let's cut the legalese. Spoliation is any action — or any deliberate failure to act — that results in relevant evidence being destroyed, altered, or made unavailable for a case.

It's not always a villain shredding documents in a fireplace. More often it's quiet and bureaucratic: a "routine" data purge that wipes out emails discussing a safety hazard, security footage that gets overwritten every 24 hours by default, a driver's logbook that goes missing during an office move. It makes no difference whether someone dragged a file to the trash themselves or let an automated system do the dirty work. If there was a duty to keep it and the evidence is gone, that's spoliation.

The "Duty to Preserve"

Here's the part the other side hopes you don't know. As a general matter, the duty to preserve evidence attaches once a party knows — or reasonably should know — that the evidence may be relevant to litigation that is reasonably foreseeable. Colorado courts have recognized that this obligation can begin even before a lawsuit is filed; the Colorado Supreme Court addressed pre-litigation preservation in Keaten (2025). The exact trigger always turns on the specific facts, but the takeaway is simple: a party can't wait until a complaint lands to stop deleting, discarding, or overwriting relevant material.

That duty covers far more than most people expect:

• Physical objects: the wrecked semi, the defective ladder, the broken sidewalk tile that caused your fall.
• Paper records: driver logs, maintenance records, internal incident reports, employee files.
• Electronic data: emails, text messages, surveillance footage, GPS data, and vehicle "black box" recorders.

Today, the real battlefield is digital. Proof lives across servers, hard drives, and the cloud — and it's terrifyingly easy to make it vanish with a few clicks. Electronically stored information, from emails to surveillance footage, is now at the center of most modern spoliation disputes.

Why Evidence Goes Missing

Sometimes evidence really is lost by accident. But often it's a cold cost-benefit calculation: the other side bets the penalty for getting caught is smaller than what the evidence would prove. Fighting over destroyed evidence takes time, money, and a real grasp of digital forensics — and they're betting you won't have the resources or the grit to push back.

Their excuses tend to follow a familiar script:

The excuses are endless, but the goal is singular: get rid of the proof. And here's the irony — destroying evidence often hurts the destroyer more than keeping it would have. Nobody hides what helps them.

What Happens When Evidence Is Destroyed

Courts don't take kindly to a party that wins by making proof disappear. When evidence is destroyed in violation of the duty to preserve, judges have a range of penalties — called sanctions — to punish the conduct and level the playing field. There's no single bright-line rule for when each one applies; a court weighs the surrounding circumstances and the harm to the other side, and the more serious the misconduct, the harsher the remedy available.

The specific remedy usually depends on how bad the conduct was — simple negligence, gross negligence, or intentional bad faith — and on how much the missing evidence actually hurts your ability to prove your case. The most common sanctions include:

Potential Sanctions for Spoliation

The adverse-inference instruction is the one that keeps corporate defense lawyers up at night. When a judge tells a jury it can assume the destroyed evidence was harmful, that's often a fatal blow — it's the court effectively saying, "You can assume they were hiding something."

One caution worth keeping in mind: winning a spoliation sanction is an uphill fight. Courts generally demand a strong showing before they'll punish a party, which is exactly why locking down evidence early beats fighting over its disappearance later.

Was It Destroyed by Accident?

"Oops, it was an accident" is the number-one excuse you'll hear. But here's the distinction that matters: even careless, non-malicious destruction can support sanctions — courts look beyond pure intent. The court isn't only looking at intent — it's trying to fix the unfairness that losing the evidence created for your case. If someone's sloppiness robs you of the ability to prove what happened, a judge can step in.

How to Protect Your Evidence

You can't leave evidence preservation to chance. The other side may already be working from a playbook built to make proof disappear, and evidence degrades fast: digital data overwrites on a schedule, physical objects get moved or repaired, and witness memories fade within days. The clock starts the moment you're injured.

Here's the essential checklist:

1. Send a preservation letter — immediately. This is a formal legal notice, usually sent by your attorney, demanding that the at-fault party and their insurer preserve all relevant evidence. It puts them on record so they can't later claim the loss was innocent.
2. Document everything yourself. Become your own investigator. Use your phone — take photos and video of the scene, your injuries, the vehicle damage, anything that might matter. You can't have too much.
3. Identify every source of evidence. Think beyond the obvious. Nearby businesses with security cameras? Bystanders who recorded the aftermath? A "black box" data recorder in the truck that hit you? Make a list.
4. Act without delay. Every other step depends on speed. Engaging an attorney quickly means preservation letters go out and investigators get dispatched before the evidence can quietly disappear.

Think creatively about where proof hides. In a slip-and-fall at a big-box store, the video of the fall rarely tells the whole story — but the store's inspection logs, employee schedules, maintenance records, and prior incident reports can reveal a pattern of negligence that's far more powerful than a single clip. Those internal records are often exactly what a company would prefer to keep buried.

Why This Is a Specialist's Fight

Proving evidence was destroyed isn't a job for someone who dabbles in injury law. It often means digging into the other side's data-retention policies, putting IT staff under oath, and bringing in forensic experts to find the ghosts in the machine — while the defense insists everything was "routine" and buries you in motions to block discovery. Cutting through that takes a lawyer who knows how to:

• Draft an airtight preservation letter that leaves no room for excuses.
• Run aggressive discovery to expose internal policies and communications.
• Depose corporate reps and IT staff with precision.
• Work with forensic experts to recover deleted data or prove protocols were violated.
• Write a brief that convinces a skeptical judge sanctions are warranted.

Common Questions

Can I sue someone just for destroying evidence?

Usually, spoliation is handled through sanctions inside the underlying injury case rather than as a separate lawsuit — a powerful tool in the main fight, not a standalone one. Whether any independent claim for destroying evidence is even available is narrow and fact-specific, so the practical move is to raise spoliation within the existing case. An attorney can tell you which path fits your situation.

How quickly do I need to act?

Immediately — yesterday would have been better. Companies often run automated deletion policies that can permanently erase emails, texts, or security footage in days or even hours. Getting a preservation letter in their hands is the single most important first step to stop that clock.

What kinds of things count as evidence?

Just about anything relevant to proving what happened. Lawyers aren't only hunting for one smoking-gun document — the cumulative weight of many pieces usually builds the strongest case:

• Emails and internal company memos
• Text messages and voicemails
• Photos and video from any source
• GPS and telematics data from commercial trucks
• Vehicle "black box" data recorders
• Maintenance logs and inspection reports
• Driver qualification files and other personnel records
• The physical items themselves — the wrecked truck, the defective product

The other side has a duty to hang onto all of it. Our job is to hold them to it.
