Outside, Sophie watched the flashing lights approach.
A memory drifted through her mind.
A few days earlier, her mother had mentioned the furnace making strange noises.
Her father had sighed while looking at a stack of bills.
“We’ll deal with it later,” he had said. “Money’s tight right now.”
Inside the Bedroom
Upstairs, the bedroom was eerily quiet.
Sophie’s parents lay in bed, unmoving. There were no signs of violence, no struggle.
But their breathing was faint.
Too faint.
Near the wall, the gas detector sat silent, its battery dead for months.
Paramedics rushed in and carried both parents out on stretchers.
The ambulance lights cut through the darkness as they loaded them inside.
Sophie stepped closer to her mother.
“Are they going to wake up?” she asked quietly.
“We’re going to do everything we can,” a paramedic said gently, squeezing her hand.
But something didn’t feel right.
The gas valve was completely open—far more than normal.
And the ventilation duct had been blocked with a towel, shoved tightly into place.
Officer Ruiz looked at the scene again.
His stomach dropped.
“This wasn’t an accident,” he said.
The Hospital
At Phoenix General Hospital, doctors confirmed Sophie’s parents had been breathing gas for hours. They were alive but in critical condition.
Meanwhile, investigators returned to the house.
The furnace itself showed no major malfunction.
Someone had tampered with it deliberately.
Whoever did it knew exactly what they were doing.
Later, in a quiet room at the police station, Ruiz sat across from Sophie.
She spoke with the simple honesty only children have.
“Daddy was really nervous yesterday,” she said. “He was yelling on the phone… he said he couldn’t pay anymore.”
“Did you hear the other person?” Ruiz asked.
Sophie nodded slowly.
“He said today was the deadline.”
The Security Cameras
Neighborhood cameras revealed something chilling.
At 11:46 p.m., a hooded man walked toward the house.
He limped slightly on his right leg.
Five minutes later, he left quickly.
He hadn’t wandered there by accident.
He knew exactly where he was going.
But the most important clue hadn’t been discovered yet.
And it wasn’t in the furnace.
What They Found Under Sophie’s Bed
Two days later, detectives returned to the house to collect more evidence.
While searching Sophie’s bedroom, Officer Ruiz noticed something under the bed.
A small notebook.
A child’s sketchbook.
