From highly anticipated book-to-screen adaptations and returning shows to adult animated comedies and stand-up specials, Netflix has something for every genre lover this September.

But if you’re a true-crime aficionado expecting a content flow as before, you’re probably stuck writing the same keywords with no significant results.

While the last few weekends were packed with the most sensationalised true-crime stories, the upcoming one will be no different, and we’re here to see it through.

So, if you’re pre-planning to avoid a last-minute unravelling, here are four new true-crime documentaries to finish in a weekend.

Four true-crime documentaries to watch in a weekend

The TikTok Killer (Héctor Muniente, 2026)

2026 has given Netflix viewers a front-row seat to the most unsettling true-crime narratives, including the two-part Spanish documentary The TikTok Killer, directed by Héctor Muniente. The true-crime documentary tells the story of Josefa “Pepa” Perez, who sees every parent’s worst nightmare become a reality when her 42-year-old daughter Esther Estepa vanishes without a trace, prompting her mother to investigate the last man who saw her before her disappearance.

The haunting tale dates back to August 2023, when Pepa receives a concerning message from her daughter. Having recently come out of an abusive relationship, Esther informs her mother that she had been street-bound for a while, which is why she plans to relocate from Spain to Buenos Aires with a friend. But when Pepa tries to communicate with her daughter the next minute, Esther’s phone is found shut off. The TikTok Killer follows Pepa’s desperate journey to find out the truth as days turn into weeks without contact.

A Child of My Own (Maite Alberdi, 2026)

Described as a hybrid documentary film directed by Maite Alberdi, A Child of My Own tells the true story of Eleonor Alejandra Marin Mendoza, a young Mexican woman who suffered multiple miscarriages and faced immense societal and family pressure to conceive a child. Desperate to fulfil the mounting expectations, Alejandra turned to faking an entire pregnancy instead of divulging her last miscarriage to her husband and in-laws.

To keep up with the ruse, she ultimately attempted to kidnap a newborn baby in 2009 from a Mexico City hospital, claiming that she arranged it with a reluctant expectant mother. However, official statements from the mother whose child had been kidnapped suggest otherwise. While the first portion of A Child of My Own unfolds like a feature film, it later transitions into a traditional documentary, featuring real-life interviews with Alejandra, the baby’s mother, and the presiding judge.

Chompoo: Lost & Forgotten (Nontawat Numbenchapol, 2026)

Marking as the first true-crime entry from Netflix Thailand, Chompoo: Lost & Forgotten is a harrowing documentary that explores the tragic 2020 disappearance and death of three-year-old Orawan “Nong Chompoo” Wongsricha. Instead of being framed as a strict procedural whodunit, the Netflix series comes across as a sharp critique of media saturation, societal obsession, and social media culture.

For those uninitiated, Nong Chompoo disappeared from her home in the secluded Kok Kork village of Mukdahan province in May 2020, and her body was found on a harsh mountain slope in Phu Pha Yon National Park, roughly 1.8kilometers away from her house following an extensive three-day search. The primary suspect turned out to be the uncle of the victim, Chaiphol “Uncle Phol” Wipha, who, rather than facing immediate social ostracisation, evolved into a bizarre media icon.

Monster: The Lizzie Borden Story (Max Winkler and Sarah Adina Smith, 2026)

Serving as the fourth instalment of Ryan Murphy and Ian Brennan’s hit anthology series Monster: The Lizzie Borden Story, the eight-episode season comes exactly a year after The Ed Gein Story, recounting the life and crimes of the titular prime murder suspect who was tried and acquitted of the 1892 axe murders of her father and stepmother in Fall River, Massachusetts. While the first three instalments focused on notorious male perpetrators, this marks the first time a female Monster takes centre stage.

Although it is not a documentary, it specifically dives deep into female rage and repression, tracking Borden’s youth in a New England household built on humiliation and abuse against the backdrop of shocking true-crime. Monster: The Lizzie Borden Story goes back in time to chronicle and dramatise her youth growing up alongside her rebellious maid in a strict, wealthy Victorian-era family, shedding light on the gruesome murders that gave birth to an icon.
