Introduction

In 2013, a woman named P. Mariammal mysteriously vanished in the city of Garacharama, in the Andaman and Nicobar Islands. Since that day, no information or updates have surfaced, and her fate remains unknown. Today, we aim to uncover new leads in this case using OSINT and our data collection skills. Let’s delve into the mystery of P. Mariammal.

How did I get into this?

One day, there was a strike at our college. The day required day scholars to go home and hostellers to return to the hostel, but my friend Sayanth and I stayed back in the computer lab since some teachers were around. We planned to dive into programming discussions, but as usual, we sometimes browsed websites listing missing persons from different Indian states, mostly out of curiosity.

On that day, I accidentally came across an old missing persons website, with cases ranging from 2004 to 2013. As I scrolled through them, I saw some truly horrifying stories. One case, in particular, stood out: a boy named Sreenivasan, who had survived the 2004 tsunami, made it to a relief camp, and was then kidnapped from there. The story was deeply disturbing and stayed with me.

As we scrolled deeper into the list, one name caught my attention: P. Mariammal. I don’t know why, but I made a note of her husband’s name: T. Ravichandran. Just below her case, I noticed another missing person: a girl named Kumari R. Brinda. What struck me was that her father’s name matched Mariammal’s husband’s name. That’s when it hit me, this was a mother and daughter who had both gone missing from the Andaman and Nicobar Islands. But beyond their names, there was no other information, just silence.

Then, as I scrolled further, I came across another name: Shri S. Chinnaiah. And that’s where the connection started to form.

Part 1: Who are they?

Here, we can clearly see that all three went missing in the same place, on the same date, within a span of just 80 minutes. That detail alone suggested some kind of hidden connection, but we weren’t sure what it was.

Driven by curiosity, we began digging deeper, researching the Andaman and Nicobar Islands during that period, looking into the lives of these people, and searching for any threads that could link them together. Who were they? What exactly happened? And most importantly, what connection ties these three missing cases into one mystery?

First, I’ll share some of the common details we found between them. After laying out those similarities, I’ll connect the dots and present our perspective on this case.

• Missing Place: All three disappeared from the same location — Garacharama.
• Languages Known: All three spoke Tamil. Additionally, both P. Mariammal and Shri S. Chinnaiah knew Hindi, while Mariammal’s daughter did not.
• Age Factor: P. Mariammal was 23 years old, and Shri S. Chinnaiah was 24 years old, almost the same age.
• Residence: Shri Chinnaiah lived in Garacharama, Ward No. III. Mariammal frequently visited her parents’ house, also located in Garacharama.
• Dress Color: A subtle but striking detail, all three were wearing blue at the time they went missing.
• The distance between Austinabad and Garacharama, Ward No. III is less than 5 kilometers, practically neighboring areas.
• Both Mariammal and Chinnaiah shared the same educational qualification: Matriculation.

Part 2: Solving the Puzzle

So, let’s begin connecting the points. The first common link is language. All three knew Tamil, and the child’s mother tongue was also Tamil. This strongly suggests that all of them had roots in Tamil Nadu.

Interestingly, both Mariammal and Chinnaiah also knew Hindi. From our research, we found that in the Andaman and Nicobar Islands, Bengali is the most widely spoken language, while Hindi comes second as a common link language. So why Tamil?

The answer lies in the large Tamil-speaking community in South Andaman. The areas of Austinabad (where Chinnaiah lived) and Garacharama (where Mariammal lived) both fall within South Andaman, which historically developed strong Tamil roots.

From history, we discovered the reasons for this:

1. British Era — Tamils were brought as convicts, laborers, and staff during the penal settlement.
2. Post-Independence — The Indian govt resettled people from Tamil Nadu (and other states) in the Andamans.
3. Fishing & Trade — Tamils’ coastal skills made them active in fishing and local businesses.

So, the first piece of the puzzle becomes clear:
👉 They all had Tamil roots.

Looking at the data, it’s clear that all three went missing from the same place, Garacharama. While we cannot yet determine the exact reason, we formed some assumptions that I’ll explain after linking the remaining details.

Next, let’s connect their age and qualification. Mariammal was 23 years old, and Chinnaiah was 24, practically the same age group. Both of them also shared the same educational qualification: Matriculation. From our research, we found that during that time, there were three popular schools in the area, which could possibly indicate a shared academic or social environment.

Schools built before 2010

1. Govt. Senior Secondary School, Garacharma

• Existed long before 2010.
• Major government CBSE school, Classes 1–12.
• One of the oldest on the Garacharma side.

2. Saraswati Shishu Mandir, Pather Gudda (Garacharma)

• Established in 1988.
• CBSE-affiliated, running primary → higher secondary.
• Popular among local communities.

3. St. Mary’s School, Bathubasti (Garacharma side)

• Founded in 2005, it was already active before 2010.
• Private CBSE school, Classes up to senior secondary.

4. Local Govt. Primary & Middle Schools (Austinabad side)

• Some small government schools existed in Austinabad even in the 1990s–2000s for the settlement community.
• Example: Govt. Primary School, Austinabad (serving local families before 2010).

We also know that Mariammal’s parents lived in Garacharama, and Chinnaiah was residing there at the time. This allows us to assume that they may have attended the same school during their studies, which leads to a strong possibility that they had known each other since childhood.

Apart from this, we know that Mariammal regularly visited her parents’ house, and that very area is where Chinnaiah’s house was located as well, just a short distance away.

Now, we move into the main part: the conclusion. The strongest clue lies in what they were wearing at the time of their disappearance. All three were dressed in blue. But why blue? What does it signify?

Before we explore that question, let’s take a look at the picture of Mariammal that was available on the site.

From this picture, we can clearly see that Mariammal is wearing a churidar, which suggests she was comfortable dressing that way. But then a striking question arises: why do the official missing details mention that she was last seen wearing a blue saree? The discrepancy between what she usually wore and what was reported raises suspicion and adds another layer to the mystery.

Now, you might think, maybe she wore a churidar for official occasions and casually preferred a saree. That could sound reasonable, right? But here’s the problem. To understand it, we need to look at the case registration details of all three missing persons.

I’ve included their case records below; just read them carefully.

From this, we can clearly see that all three were described as wearing a formal dress code at the time of their disappearance.

Part 3: Our Assumptions

From this point onward, what I’m going to share is entirely our own perspective. Nothing here is officially confirmed; these are simply the conclusions we arrived at through our research and analysis of the available details.

Perhaps P. Mariammal and Chinnaiah shared a relationship and had planned to elope along with her daughter. The choice of wearing the same color code: blue formal dress, might have been intentional, creating the appearance of a family unit to anyone who saw them. It’s also possible that Mariammal’s frequent visits to her parents’ house were not just family visits, but opportunities to meet Chinnaiah.

From this, we arrive at three possible outcomes:

1. They successfully eloped and disappeared together.
2. They were murdered during their attempt, possibly after their relationship was discovered by her or their families.
3. Or, something even worse happened to them on that day.

But one thing is certain: whatever happened, the three cases are undeniably connected.

Conclusion

Our curiosity was sparked by the many common factors in this case, which is why we gathered every piece of available information. Unfortunately, we cannot push this investigation further. Traveling to the Andaman and Nicobar Islands for deeper research is beyond our current reach as students, both financially and logistically.

Still, we made efforts to connect with people from the islands, hoping to uncover new insights that could confirm one of our theories. If such a breakthrough ever happens, I will definitely share an update with you all.
