Cold Case K-9 — Caridad Pineiro

Only a competent K9 and her handler

Could find her sister's killer.

CBI Agent Gabriella Ruiz is convinced a missing hiker is a reemerging serial killer's next victim. Believing she's too close to the case, the Bureau refuses to follow her hunch. Luckily, Gabriella finds unexpected help in Crooked Pass Security's unique investigative team. Expert tracker Diego Rodriguez and his faithful K-9, Poppy, go searching for clues from the ground up. But when the killer focuses on Gabriella, Diego -- and Poppy -- must keep her safe from the killer's dangerous grasp.
