At dawn, during a routine patrol of the area, Eric noticed a saguaro with a suspicious swelling at shoulder level. The report would later call it an “anomalous growth,” but in person, it looked as if the cactus had swallowed something.

Instructions said not to interfere, but Eric acted carefully and methodically—he made an incision while Dana watched, the radio crackling with static. The blade first struck metal, then fabric—the object was tightly wedged inside.

Officer Thomas had already left for the scene, and Dr. Sophia had previously warned about caches in the desert—everything from drugs to weapons. But this was something else.

The object inside trembled.

In a panic, I transmitted the coordinates to Thomas, duplicating them with the GPS tag on my tablet.

A patrol SUV pulled up, raising a cloud of dust.

“Report,” Thomas demanded, stepping out.

I briefly outlined the situation. Dana handed him new gloves. He examined the markers and contacted dispatch, confirming jurisdiction.

Then they set up an additional perimeter—orange cones at a distance of sixty feet.

In silence, Dana handed me the clamps. The object inside moved and caught on a rib. There was a click—the mechanism released.

We saw a microcassette recorder in a dingy plastic case, rewound with tape. I carefully removed it and laid it on sterile foil.

After connecting the backup power, I pressed “play.” Dana raised the microphone.

A hoarse voice rang out:

“Eric… if you can hear this, answer.”

I whispered the coordinates, feeling fear mingle with hope.

A white pickup truck slowly approached from the east. It was Dr. Sophia, with containers and a refrigerator for samples. We continued our work, following the “Flag One” marker. After digging up the topsoil, I discovered darkened earth.

“This is where it all ends,” I said.

The permit was approved, and the rangers arrived. We were informed that the recorder had been sold a year ago at an electronics store in Tucson.

Footprints in the sand led to the road. New messages appeared: a fire pit, three stones in a triangle, ash. Sofia found remnants of fabric, under which were human remains.

Later, at headquarters, we plotted maps and a timeline.

“Partial number: 7-K-X,” Dana added.

That evening, a white pickup truck appeared at kilometer sixteen. The vehicle stopped. Thomas approached first.

“Good evening. Turn off the engine and show me your hands.”

The driver introduced himself: Hector Ruiz, contractor. We recorded the tire tracks and collected samples. The lab report soon arrived: the burlap matched the Desert Agro Supply shipments—a rare jute blend with blue thread.

A judge’s warrant authorized the seizure of the truck. The GPS device was dismantled.

The final act came in the lab.

“The dental x-rays are ready,” Dr. Rivera reported.

He compared the data with the case of the missing person.

“It’s a DEA informant who disappeared in Tucson,” he said quietly.

Ruiz’s arrest rocked the entire county.

And it all started with a cactus that wasn’t supposed to keep a secret.
