Can a Document Examiner Trace the Author of an Anonymous Letter?
Anonymous letters are some of my favorite cases to work.
Sometimes someone leaves a nasty note on your car and you want to know who did it. That’s just a car — no lasting harm. But then there’s the other end of the spectrum. What about a murder? What about Sirhan Sirhan, and other cases where handwriting became a key piece of evidence?
Famous Anonymous Letter Cases
Remember the JonBenét Ramsey case? That ransom note was, technically, an anonymous letter. Nobody knows who wrote it. Investigators had to run dozens of suspects to see whose handwriting matched. That’s a case I can’t speak about publicly, because I spoke with John Mark Karr — a pretty interesting conversation. His handwriting was the most similar to the ransom note of anyone they looked at. Does being the likely author of the note mean he killed her? That’s the question still hanging in the air thirty years later.
What It Takes to Solve an Anonymous Letter Case
You can determine the authorship of an anonymous letter. You just need the right suspect pool — meaning two or three viable suspects.
This comes up constantly in companies and in HOA disputes — including the kind of homeowners’ association conflicts we see across Collin and Denton County. Somebody needs to know which employee or which neighbor is sending the threats. To get there, and it isn’t cheap, you need both the anonymous letter and handwriting samples from the suspect pool. That might mean employee files from dozens or even hundreds of people, narrowed down to the five or ten who had a reason to write it.
It’s genuinely easy to do when you have enough writing from the suspects and enough writing in the letter. The trouble comes when there isn’t much to work with. I’ve had people say, “Well, it’s a typed letter, and all we have handwritten is a short address and a zip code.” That’s not a lot — especially in printed form.
When the Stakes Are High
Generally it’s three things that solve these cases: the quantity of writing, the quality of writing, and the pool of suspects. We’ve even worked anonymous writing on a bathroom wall. It happens — a student gets accused of writing something, gets suspended, and suddenly their college prospects are on the line. The parents say, “We know he didn’t write that. He told us he didn’t. We need a letter from you to prove it.”
Whether or not we can ever share the outcome, the point is that these cases matter enormously to the people living through them. There’s a lot at stake. On a case like this, it’s worth spending thousands of dollars on a forensic handwriting expert — the kind of work we call anonymous letters, or anonymous writing.

Frequently Asked Questions
Can a document examiner trace the author of an anonymous letter?
Yes — authorship of an anonymous letter can be determined given the right suspect pool of two or three viable suspects, plus the letter itself and handwriting samples from the pool.
What solves anonymous letter cases?
Generally three things: the quantity of writing, the quality of writing, and the pool of suspects. A typed letter with only a short handwritten address and zip code offers very little to work with.
Where do anonymous letter cases come up most?
Constantly in companies and HOA disputes — someone needs to know which employee or neighbor is sending threats. That can mean narrowing employee files from hundreds of people down to the five or ten with a reason to write it.
Are anonymous letter cases worth the cost?
When the stakes are high, yes. Cases range from workplace threats to a student accused of writing on a bathroom wall with college prospects on the line — situations worth spending thousands on a forensic handwriting expert.
