Chapter 5 - THE DOCTOR’S CONFESSIONInside the sterile, fluorescent-lit interrogation room of the Federal Investigative Police headquarters in Guadalajara, the atmosphere was thick with the smell of cheap coffee and institutional despair.

Dr. Leonardo Estrada sat at the center of the stainless-steel table. His once-impeccable white lab coat was crumpled, his tie loosened, and his fingers interlocked nervously as he stared at the two-way mirror across the room.
The door swung open, and Commander Héctor Vance walked in, tossing a thick stack of medical files onto the metal table with a sharp slap that made the doctor flinch.
“I want my legal counsel,” Estrada stammered, adjusting his wire-rimmed glasses with trembling fingers. “You’re holding me under false pretenses. I am a licensed medical professional of this commonwealth. I demand—”.
“You demand nothing, Doctor,” Vance interrupted, pulling out a chair and sitting down directly across from him. He leaned forward, resting his forearms on the table. “Let’s talk about Héctor Vargas. Let’s talk about Ricardo Silva. And, of course, let’s talk about the cocktail of potassium chloride and synthetic paralytics you prescribed for elderly widowers under the guise of 'cardiac support vitamins.'”
Estrada swallowed hard, his Adam’s apple bobbing violently. “Those... those are standard prescriptions for palliative care. Medical science is complex, Commander. Autopsies can be misinterpreted—”
“Autopsies can be misinterpreted?” Vance cut him off, sliding a forensic report across the table. “These aren't local village autopsies, Estrada. These are federal exhumation reports conducted by independent pathologists in Mexico City. Every single victim in this folder had lethal concentrations of synthetic muscle relaxants in their liver tissue—doses administered precisely forty-eight hours before their official 'heart attacks.'”
Vance tapped a finger against a specific signature line on the bottom of a death certificate.
“And right here, in your own handwriting, you certified natural causes while pocketing forty percent of the life insurance payout funneled through Marisol Salgado’s shell accounts in the Cayman Islands.”
The room went dead silent. The heavy weight of undeniable proof pressed down on the doctor until his shoulders slumped completely. The defiance vanished from his eyes, replaced by a pathetic, hollow resignation.
“She... she promised me we’d retire in Costa Rica,” Estrada whispered, his voice cracking. “I didn't kill them with my own hands. I just... I just adjusted the charts. I signed the papers. Marisol was the mastermind. She found the men, she gained their trust, she managed the household staff, and she executed the transfers.”
“And Kevin?” Vance asked, his eyes narrowing. “What was the boy's role?”
“Kevin was the closer,” Estrada muttered, staring blankly at the metal table. “He was young, innocent-looking, easy to manipulate into forging signatures on minor property deeds, and ruthless enough to terrorize anyone who stood in the way of the operation—including her own stepson.”

Vance stood up, buttoning his jacket. “Save the sob story for the federal judge, Doctor. Your confession has been recorded, timestamped, and matched against the financial ledgers recovered from Querétaro. You’re going away for a very long time.”
As Vance turned and walked out of the interrogation room, leaving Estrada weeping into his hands, the final piece of the criminal syndicate had officially crumbled into dust.
