A police dog attacked a 16-year-old student and began barking loudly: when the police took the girl’s fingerprints, they discovered something horrifying 
At City High School No. 17, it was decided to hold an “open lesson” on safety. In the auditorium, senior students, teachers, and parents gathered. A police dog handler with his service dog, a German Shepherd named Rex, was invited.
The uniformed officer confidently stepped onto the stage with Rex. The dog was calm, even slightly lazy—walking casually beside him, but his eyes constantly scanned the room. The students exchanged glances and whispered to each other.
“This is not just a dog,” the officer said with a smile, “he is my partner. And he never makes a mistake.”
He demonstrated a few commands: Rex found a fake pistol hidden in a backpack and even lay down next to a person who had a special marker in their pocket. The children clapped.
But suddenly, everything changed.
As the officer was about to finish the demonstration, Rex suddenly became sharply alert. His ears perked up, the hair on his neck stood on end. He froze, staring at the crowd of students. And then… he lunged forward with a growl.
“Rex! Stop!” shouted the handler, but the dog did not obey.
The German Shepherd lunged at a girl in the third row, barking loudly. She was a modest, quiet student named Marie—she usually sat in the back rows. Today, she stood next to her friends, holding a notebook against her chest. At first glance, she looked like an ordinary, shy girl.
But Rex was charging at her as if he had gone mad. He growled, bared his teeth, and then jumped on her, knocking her to the floor. The girl screamed, the notebook flew, and panic erupted. The teachers tried to pull the dog away.
“Fu, Rex! Lie down!” shouted the handler, grabbing the collar and barely managing to pull the Shepherd back. But the dog still kept his gaze fixed on Marie.
The officer was stunned:
“He never behaves like this without reason… never.”
The student was trembling, her eyes filled with tears. Everyone assumed the dog had confused the scents. But the officer insisted:
“Miss, I need you and your parents to come with me to the station. We need to check something.”
The parents tried to protest, shouting about “shame on the whole class,” but the dog continued to growl, and arguing with his instincts was pointless.
When the girl arrived at the station, her fingerprints were taken. And then the officers were horrified. The computer showed a match 
Continuation in the first comment 
The prints belonged to a woman registered in the federal database of wanted criminals.
The officer slowly turned to the trembling “student”:
“Do you want to tell it yourself… or should I read the file?”
The girl took a deep breath, and suddenly her entire expression changed. From a timid, frightened schoolgirl, she transformed into a cold, adult woman with eyes that had seen too much.
“Alright… enough playing,” she said in a low, confident voice.
It turned out her real name was Anna, and she was already 30 years old, not 16. Due to a rare genetic condition, she still looked like a teenager: small stature, childlike facial features, thin voice.
Anna had been hiding from the police for several years, living in different cities. Her file included robberies, fraud, and involvement in jewelry thefts.
Fingerprints had been found on safes, doorknobs, in apartments… but each time she escaped pursuit because no one could believe that a “teenage girl” was behind the crimes.
She attended different schools, lived with families under the guise of being an orphan, and constantly changed her name. No one suspected that an adult woman was sitting among the children.
“No one would have recognized me,” she smirked. “If it weren’t for your damned dog.”
“You see, Anna,” he said coldly, “humans can make mistakes. But my partner—never.”
