The Lindbergh Baby Case: Handwriting Evidence Has Solved Crimes for Over a Century

People often ask a simple question that actually has a very technical answer: Can a handwriting expert really tell if a signature is forged?
Yes… and we can tell who wrote a ransom note, too.

Handwriting Evidence Has Solved Crimes for Over a Century… and we still use it in courtrooms in Texas.

My name is Bart Baggett. I’m a forensic document examiner, and for decades my work has involved examining handwriting and signatures in legal disputes. In cases across the country — including matters involving wills, contracts, and financial documents — trained experts can determine whether handwriting is authentic or forged.

This type of analysis isn’t new. Courts have relied on handwriting examination for well over a century.

Handwriting Evidence Has Solved Crimes for Over a Century

One well-known example comes from the Lindbergh baby kidnapping case in the 1930s. A ransom note demanding $50,000 was left in the child’s nursery. Investigators later compared the handwriting on that note with banking documents connected to the ransom money. I hosted an indepth video here about it.

Handwriting analysis helped investigators connect the suspect to the crime.

That case happened in 1935. Even then, forensic handwriting comparison was already a recognized investigative and courtroom tool.

Is Handwriting Really Unique to Each Person?
Yes, it is.

Handwriting develops through years of muscle memory, habit, and small unconscious movements. Even people who learned the same cursive style in school end up writing differently over time.

Those small variations are what forensic document examiners study.

Much like fingerprints, handwriting carries patterns that are highly individual. When enough quality writing samples are available, those patterns can be compared with surprising precision.

Where Forgery Questions Usually Appear in Legal Cases

In my experience, the most common disputes involving handwriting are not celebrity autographs or sports memorabilia.

They are legal documents.

Wills. Contracts. Estate documents. Business agreements.

In the Dallas–Fort Worth, Texas area, for example, disputes often arise around handwritten or “holographic” wills. When an entire page of handwriting is questioned, the examination becomes much more detailed than simply comparing signatures.

Forging a full page of natural handwriting convincingly is extremely difficult. Even skilled imitators tend to leave clues behind.

Frequently Asked Questions

How long have courts relied on handwriting examination?

Well over a century. The Lindbergh case happened in 1935, and even then forensic handwriting comparison was already a recognized investigative and courtroom tool — one still used in Texas courtrooms today.

The Strangest Handwriting Related Double Murder Cases I’ve Worked

The Wildest Handwriting Cases I’ve Seen — And Why Handwriting Still Matters in Texas Legal cases

If you work long enough as a forensic handwriting expert in Dallas or the USA… you start to see patterns. Most cases are quiet, methodical, and focused on documents that never make headlines. But every once in a while, a case comes along that reminds you how unusual this work can get. And more importantly, why precision and clarity matter so much when the stakes are high.

When people ask me about the “craziest” case I’ve worked, two situations come to mind. Not because they were dramatic for the sake of drama—but because they highlight how handwriting evidence shows up in very different environments. One was inside a jail, face-to-face with a serious criminal suspect. The other unfolded under the bright lights of national media attention.

 

When Handwriting Evidence Meets Real-World Violence

Early in my career, I was asked to assist on a criminal case involving a double homicide. My role was straightforward: obtain handwriting samples from the suspect and evaluate whether certain markings could be connected to him.

The unusual part wasn’t just the crime—it was the evidence. Investigators had recovered a tarp covering two bodies, and on that tarp was graffiti believed to be gang-related. The question was whether that writing could be tied back to the individual in custody.

Here’s where people often misunderstand handwriting analysis. Not all writing is created the same. Gang tagging, for example, is often stylized. It’s expressive. Sometimes intentionally distorted. That makes it very different from everyday handwriting—and it requires a different level of interpretation.

In Texas, where courts regularly handle a wide mix of criminal and civil cases, this distinction becomes important. A busy system like the Plano, Dallas, Fort Worth Courts… we see everything from contract disputes to serious criminal matters. When handwriting evidence enters that environment, it has to be explained clearly, without assumptions.

What stood out to me personally in that early case wasn’t tension or hostility. It was the opposite. The suspect was cooperative. Calm. He provided the requested writing samples without resistance. And interestingly, his natural handwriting—separate from any graffiti—was unusually precise and controlled.

That’s something you learn quickly in this field. People are rarely what you expect them to be. And handwriting, when evaluated properly, reflects patterns—not personalities.

Frequently Asked Questions

What was the double homicide handwriting case about?

Investigators recovered a tarp covering two bodies with gang-related graffiti on it. The examiner’s role was to obtain handwriting samples from the suspect in custody and evaluate whether those markings could be connected to him.

Is gang graffiti analyzed like normal handwriting?

No. Gang tagging is often stylized, expressive, and sometimes intentionally distorted — very different from everyday handwriting, requiring a different level of interpretation.

How did the suspect behave during the jailhouse examination?

Cooperative and calm. He provided the requested writing samples without resistance, and his natural handwriting — separate from any graffiti — was unusually precise and controlled.

What does handwriting actually reveal to an examiner?

When evaluated properly, handwriting reflects patterns — not personalities. People are rarely what you expect, which is why evidence has to be explained clearly and without assumptions.

Do Signatures Change Over Time?

When Signatures Change Over Time: How Dallas Courts Still Identify Forgery

In Dallas, Texas, questions about signatures come up more often than you might think. Wills, contracts, deeds, and business documents all hinge on one small detail — a name written on paper. And one of the first concerns people raise is simple and reasonable: “What if the signature doesn’t look like it used to?”

The short answer is yes — a forensic handwriting expert can still identify a forgery even when a signature has changed over time. In fact, that’s not a complication. It’s part of the job.
