AceShowbiz - Just a few years after the phenomenal success of The Tinder Swindler, Netflix has launched a gripping new true-crime documentary series that many are calling a "darker" successor to that hit. This fresh offering is a two-part series that delves into a chilling case set in Spain, spanning multiple decades—from the age of landline phones to the rise of social media platforms like TikTok. Since its debut, the show has quickly become one of the most-watched titles on Netflix’s global and domestic charts, alongside the Danish true-crime series A Friend, A Murderer.

The series centers on the mysterious disappearance of a 42-year-old woman some years ago and the relentless search led by her mother. The mother uncovers that her daughter had been traveling around Spain with an elderly man who enjoys a significant following on TikTok. This man, later identified as José Jurado Montilla, reached out to the mother expressing sorrow over the woman’s disappearance and promised to revisit their journey to find clues that could help the investigation.

Complicating matters, the mother began receiving suspicious text messages from her daughter’s phone, indicating a desire to leave Spain and start anew in Argentina. These messages raised her suspicions, prompting her to scrutinize Montilla, the last person reportedly seen with her daughter. What she discovered shocked her: Montilla harbors a dark history involving multiple deaths and has previously served a long prison sentence.

Named The TikTok Killer, the documentary follows the familiar Netflix true-crime style, combining interviews with key figures and dramatic reenactments. Fans of the genre will recognize these narrative techniques, similar to those dissected with humor in the acclaimed The Zodiac Killer Project. The series also features numerous clips from Montilla’s TikTok videos, in which he aggressively denies accusations and claims to have had a relationship with the missing woman—a claim her family firmly rejects.

This new true-crime series is designed to be highly bingeable, offering viewers a deep dive into the unsettling story through a modern lens, where social media plays a significant role in both the investigation and the storytelling. Netflix’s strategy of marketing it as a follow-up to The Tinder Swindler seems to have paid off, as audiences who were drawn to the earlier documentary are now showing strong interest in this chilling tale from Spain.

The popularity of The TikTok Killer alongside A Friend, A Murderer demonstrates the continuing global appetite for true-crime content on streaming platforms, with Netflix leading the charge. Both shows hold prominent positions on FlixPatrol’s rankings of the most-watched Netflix series worldwide and within specific countries.

For viewers intrigued by true crime and the complexities of modern investigations affected by social media, The TikTok Killer offers a compelling narrative packed with suspense and emotional depth. The series is available now for streaming on Netflix, inviting audiences to uncover the dark secrets behind this mysterious disappearance and the unsettling character at its center.
