概要
 True Crime Mastermind — true crime stories for listeners who can't let go of a case. A true crime podcast by OBOMEDIA, built on real events.

Every true crime story in our archive begins with a question no one could answer: an unsolved murder, a cold case reopened decades later, a mysterious death the coroner couldn't explain, a disappearance that never made sense.

Open the crime files with us. Each episode follows the crime investigation from the first call to the trial — how investigators build a murder case, where a police investigation goes cold, and what justice looks like when it arrives late, or never arrives at all. Some episodes hunt a serial killer who hid in plain sight. Others reconstruct a family murder that tore a town apart, or a murder mystery that turned neighbors against each other.

And then there are the missing: a missing person report filed too late; missing persons whose trails went cold within days; a missing woman last seen leaving work; a missing girl whose face was on every screen in the country; a missing man found dead years after he vanished; the missing and murdered whose names deserve to be remembered. We tell every crime story with respect for the victim, for the families, and for those who survived.

From the infamous case the whole world watched to the unsolved case you have never heard of, from classic true crime to dark true crime and disturbing true crime, our true crime reports bring you real crime stories, real murder cases, true murder stories and unsolved mysteries — one true crime case at a time, straight from the OBOMEDIA true crime vault. Because if a killer is still out there, the story is not over.

    Daughter Prints Missing Posters While Mom's Body Is in Her Washer

    On October 17, 2025, neighbors in Guayaquil, Ecuador, reported a disturbing smell, leading police to a missing woman's apartment. What they found inside-the body of Marta Cecilia Solis Cruz-revealed a shocking truth: the woman whose disappearance the entire neighborhood had been following, whose face was on flyers taped to lampposts, had never left the building at all.

    In this episode, we analyze the case of Marta Cecilia Solis Cruz, a 49-year-old woman whose disappearance turned into a murder investigation with her own daughter at the center. We explore the forensic evidence, digital trails, and the chilling deception that led investigators to question everything they thought they knew about this family.
