At night, Gab arrived at the forensics lab, the smell of disinfectant and chemicals filling the air. The fluorescent lights flickered slightly as he stepped inside, scanning the room for the lead forensic specialist. Dr. Felipe Navarro, an older man with graying hair and tired eyes, looked up from his workstation as Gab approached. "You’re here about the body, aren’t you?" Dr. Navarro said, rubbing his temples. Gab nodded. "Yeah. Any useful findings?" The doctor sighed and gestured toward a table where a set of scanned images and blood samples were laid out. "We checked everything. Cause of death was clear—single, precise strike to the chest. No hesitation, no struggle. But…" Gab raised an eyebrow. "But?" Dr. Navarro picked up a small vial filled with a strange, inky black substance.
