Selection at a glance
These Netflix true crime documentaries span feature-length films and multi-episode series, with each format shaping how a case is presented. The selection covers different kinds of real-life crime stories, from murder investigations to deception and online sleuthing. A comparison of subject and storytelling approach helps distinguish interview-led accounts from narratives built around legal records, online material or recorded media. Netflix association does not guarantee current UK catalogue availability, which can change.
Selected titles and scope
The five selections are The Tinder Swindler, The Keepers, Making a Murderer, Don’t F**k with Cats: Hunting an Internet Killer and American Murder: The Family Next Door. They are associated with Netflix productions and include both feature documentaries and multi-episode series. The mix offers different ways into true crime: accounts from people connected to a case, examinations of criminal investigations and stories shaped by digital or recorded material.
This is an editorial guide to notable Netflix true crime films and series, not a ranked list or a live catalogue inventory. The titles are grouped by broad subject, format and storytelling approach, rather than by a claim that one is more definitive or compelling than another. That distinction matters when comparing a film’s concentrated narrative with a series’ room to develop multiple strands across episodes. UK catalogue availability can change over time.
Comparison by subject and format
The table separates each title’s central subject from its format and the material used to tell the story.
| Title | Broad subject | Format | Storytelling approach |
|---|---|---|---|
| The Tinder Swindler | Romance fraud and the accounts of people who say they were deceived. | Feature documentary | Interview-led, bringing personal accounts together with digital communications and other material used to trace the story. |
| The Keepers | A murder case and the questions and allegations connected to it. | Multi-episode series | Interviews and testimony are set alongside investigative reporting, allowing related accounts to develop across episodes. |
| Making a Murderer | A criminal case examined through investigation and legal proceedings. | Multi-episode series | Interviews and legal records shape an extended account of the case and the arguments raised during proceedings. |
| Don’t F**k with Cats: Hunting an Internet Killer | An online search linked to a criminal investigation. | Multi-episode series | Online material and participants’ accounts show how internet users followed clues, with official evidence forming a separate part of the story. |
| American Murder: The Family Next Door | A family murder case presented through material associated with those involved. | Feature documentary | Recorded media and digital material, including communications, carry much of the narrative rather than a conventional interview-led structure. |
The formats distinguish concise film narratives from series that can follow several strands over multiple episodes. Across these Netflix true crime series and films, the storytelling ranges from testimony and court records to online material and recorded media.
The Tinder Swindler
Released by Netflix in 2022, The Tinder Swindler follows women who describe alleged deception linked to Simon Leviev, born Shimon Hayut, whom they encountered through dating apps. The film builds its account around their recollections, recorded interviews and material they share. Its focus is not only the reported financial losses, but also how trust and urgency feature in the women’s accounts. Separating those accounts from independently established legal outcomes helps clarify what the documentary presents and what courts have determined.
Focus and accounts
The Tinder Swindler centres on the experiences of Cecilie Fjellhøy, Pernilla Sjöholm and Ayleen Charlotte, who recount encounters with Hayut and describe what they say happened afterward. Their interviews provide the film’s main narrative thread: they explain how an apparent relationship developed, how requests for financial help were presented, and how they interpreted those requests at the time. These are personal accounts, not detached narration, so the sequence of events is shaped by the speakers’ memories and perspectives.
The women describe a pattern in which Hayut allegedly presented himself as the son of a wealthy diamond businessman and claimed that he faced danger from enemies. In their accounts, urgent requests for money followed, with loans and credit used to meet the demands. The film pairs their recollections with messages, photographs, documents and recordings supplied or discussed by the participants. That material gives viewers a view of how the women say communication unfolded, while the interviews convey its emotional and financial consequences. Rather than relying on a conventional narrator, the documentary lets the participants explain their choices and compare experiences, making their testimony central to its account of alleged deception.
Claims and established findings
The film presents the women’s allegations that Hayut deceived them and obtained money through urgent appeals. Their reported experiences and the documentary’s arrangement of interviews and records are evidence of what participants say they experienced; they are not, by themselves, a court judgment on every allegation. Editing also determines which moments appear together, so the film’s narrative should be distinguished from an independently tested account of every transaction.
A separate legal outcome is established: in Israel in 2019, Hayut was convicted of theft, fraud and forgery in a case unrelated to the women featured in the film. He received a 15-month prison sentence and was released after five months. That conviction should not be treated as a ruling on the documentary participants’ claims. Keeping the distinction clear allows viewers to consider the film’s testimony without presenting reported allegations, documentary framing and official findings as interchangeable facts.
The Keepers
The Keepers is a seven-episode Netflix true crime docuseries released in 2017. It revisits the 1969 killing of Baltimore teacher and nun Catherine “Cathy” Cesnik while following accounts from former students at Archbishop Keough High School. The series connects those accounts to questions about whether abuse allegations and the murder investigation intersected. Interviews, archival material and reporting shape its account, but the threads do not carry the same evidentiary status. Its central distinction is between what witnesses say they experienced and what investigators established about Cesnik’s death.
Murder case and connected allegations
Cesnik, 26, taught English and drama at Archbishop Keough High School in Baltimore. She disappeared on November 7, 1969, and her body was found on January 3, 1970, in a wooded area near Lansdowne, Maryland. The murder remains unsolved. The Keepers follows the case alongside accounts from former students who say they experienced sexual abuse by Joseph Maskell, a priest and chaplain at the school.
Those accounts become part of the documentary’s investigation because some former students believed the abuse allegations were connected to Cesnik’s death, or that people with relevant knowledge had not come forward. The series traces their efforts to revisit the case and examine possible links, using interviews, records and the recollections of people close to the school. It presents the allegations as a significant line of inquiry, not as a proven explanation for the murder. The documentary’s focus is therefore broader than identifying who killed Cesnik: it also examines how former students’ accounts shaped efforts to assess the circumstances around her death.
Testimony and findings
The series includes former students’ testimony describing alleged abuse by Maskell and their recollections of events at Keough. These are personal accounts presented by the speakers; they should not be conflated with a court finding that Maskell murdered Cesnik or that a particular person concealed the crime. The documentary records what interviewees say and how those accounts inform their search for answers.
The established outcome of the murder investigation is that no one has been convicted of Cesnik’s killing. Maskell died in 2001 without being charged in the murder. In 2017, Baltimore County police reported that DNA testing excluded him as the source of DNA evidence collected in the case. That result did not identify the killer or resolve the case. The distinction between the witnesses’ allegations, their testimony and these documented investigative outcomes is essential for assessing what the series presents.
Making a Murderer
Among Netflix true crime documentaries, Making a Murderer stands out for following a Wisconsin criminal case through investigations, trials and appeals. Filmmakers Laura Ricciardi and Moira Demos focus on Steven Avery and his nephew Brendan Dassey, using interviews alongside courtroom material. The series connects Avery’s earlier wrongful conviction with the later prosecution involving Teresa Halbach’s 2005 disappearance and death. Its account can be read alongside the verdicts and subsequent court decisions, which provide a separate record of the case.
Criminal case and legal proceedings
Making a Murderer follows Steven Avery’s path from a wrongful conviction to a later murder prosecution in Manitowoc County, Wisconsin. In 1985, Avery was convicted of the sexual assault and attempted murder of Penny Beerntsen. DNA testing led to his exoneration and release in 2003. In 2005, he was arrested in connection with the death of Teresa Halbach, a photographer last seen at the Avery family salvage yard on October 31.
The series tracks the investigation and the court cases that followed. Avery was convicted of Halbach’s murder in 2007 and sentenced to life in prison. His nephew Brendan Dassey, who was 16 during the investigation, was tried separately and also convicted in 2007. Interviews with Avery, Dassey, their relatives, lawyers and investigators sit alongside trial testimony and other courtroom material, giving viewers a sense of how evidence and competing accounts were presented.
Rather than treating the case as a single mystery, the Netflix true crime series follows legal proceedings across multiple episodes. It gives particular attention to the prosecution’s evidence and the defense’s challenges, including questions raised about the investigation and Dassey’s confession. The trial outcomes, however, were guilty verdicts in separate proceedings, not conclusions reached by the documentary’s interviewees or filmmakers.
Documentary framing and later developments
The series places defense arguments, family interviews and investigative footage prominently in its narrative, while courtroom records show how juries assessed the evidence under the law. Allegations that evidence was planted or that investigators acted improperly are presented as part of the dispute; they should not be confused with findings that a court established. The distinction matters when comparing the documentary’s edited sequence of events with trial testimony, rulings and the full legal record.
Later proceedings did not overturn the convictions. Avery’s post-conviction efforts did not result in a new trial. Dassey’s conviction was challenged in federal court: a federal appeals panel initially ordered relief, but the Seventh Circuit Court of Appeals, sitting en banc, reinstated the denial of his habeas petition in 2017. The US Supreme Court declined to review his case in 2018.
These developments add legal context beyond the series’ original presentation. The episodes offer a crafted account of a high-profile case; verdicts, appellate decisions and the underlying court record remain the sources for what courts decided.
Don’t F**k with Cats: Hunting an Internet Killer
This three-episode Netflix true crime docuseries follows an online community whose members investigate videos showing kittens being killed. Their search for the person responsible eventually intersects with the 2012 murder of Jun Lin in Montreal. Interviews with key participants explain how internet users compared images, accounts and clues across online platforms. The series places that activity alongside the criminal case and its formal investigation. Its central distinction is between information crowdsourced online and evidence tested through legal proceedings.
Online investigation and criminal case
The series begins with videos posted online in 2010 that show kittens being killed. Viewers disturbed by the footage form a Facebook group and work to identify the person behind it. The documentary follows members including Deanna Thompson and John Green as they compare details visible in clips and photographs, trace online accounts and discuss possible locations. Their work is collective and largely remote: participants exchange observations across platforms rather than conducting police interviews or controlling a formal investigation.
As the online search develops, the group connects its target to Luka Magnotta. The story then shifts to the 2012 murder of Jun Lin in Montreal, making clear that the earlier videos and the later homicide are related parts of the case, but not the same event. The documentary uses participant interviews to reconstruct how internet clues shaped the group’s pursuit and how the case escalated beyond the online community’s original focus. It also shows the emotional strain of watching disturbing material and trying to interpret incomplete information. The result is a crime narrative told partly through the sleuths’ changing theories and partly through the known criminal case, rather than a simple account of police work alone.
Online material and official evidence
Images, usernames, posts and location clues examined by online participants are leads and records of internet activity; they are not automatically proof of a crime or of who committed it. Crowdsourced analysis can draw attention to a pattern, suggest a person to investigate or help locate material, but its conclusions depend on context and verification. A screenshot or visual resemblance, for example, does not by itself establish when an image was made, who posted it or whether it is authentic.
The criminal case required evidence handled and presented through official procedures. In Magnotta’s trial, the prosecution relied on evidence including video recordings and forensic findings, which jurors considered within the court process. That formal record has a different status from theories discussed in a Facebook group or clues assembled from public posts. The documentary brings both strands together, but they should not be conflated: online investigation contributes to the story of how attention gathered, while legal findings establish what was proven in court.
American Murder: The Family Next Door
Released on Netflix in 2020, American Murder: The Family Next Door recounts the Watts family killings in Frederick, Colorado. Rather than relying mainly on retrospective interviews, the film builds much of its account from material recorded before and during the investigation. Domestic images and digital exchanges appear alongside law-enforcement recordings. This structure makes the surviving record central to the film’s presentation of the case.
Family murder case
The film focuses on the 2018 murders of Shanann Watts and her daughters, Bella and Celeste, in Frederick, a community near Denver. Shanann was 34 and about 15 weeks pregnant; Bella was four and Celeste was three. On August 13, Shanann’s friend reported her missing after she could not reach her. Chris Watts told responding officers that his family had disappeared.
The investigation established that Chris Watts had killed his wife and daughters. Shanann’s body was found in a shallow grave at an oil-site property where he worked, and the girls’ bodies were recovered from oil tanks at the same site. Watts pleaded guilty on November 6, 2018, to the murders and the unlawful termination of Shanann’s pregnancy. He was sentenced to life in prison without the possibility of parole later that month.
The documentary follows the case from the missing-person report through the investigation and guilty plea. Its focus is the documented sequence of events and the evidence gathered by authorities, rather than speculation about what happened inside the family or an unproven motive.
Digital and recorded material
The film combines online records and recordings to show how investigators traced events and how the case unfolded publicly.
- Social media posts and photographs show moments Shanann shared about family life, offering a contemporaneous record rather than a later reconstruction.
- Text messages between family members and others appear as evidence of communications and help establish the timeline presented in the film.
- Home videos capture ordinary interactions among Shanann, Chris, Bella, and Celeste, placing family scenes beside the subsequent investigation.
- Police body-camera footage records officers’ response at the Watts home on August 13, including their initial contact with Chris.
- Recorded law-enforcement interviews show investigators questioning Chris and document statements made as the missing-person inquiry developed.
These materials give the film its chronology and let viewers see the original recordings alongside the investigation’s findings.
Choosing from these titles
These Netflix true crime documentaries vary in both subject and storytelling format, from a single feature film to a multi-episode investigation. Their material ranges from interviews and court records to online posts, home video and police footage. Comparing those choices can help match a title to an interest in legal proceedings, personal accounts or digital evidence. Production association alone does not confirm present availability in the UK, where catalogue listings can change.
Compare subject and storytelling format
The table compares each title by the case at its centre, its screen format and the material used to tell the story. These differences matter if you prefer a compact film or a longer account built across episodes.
| Title | Case subject | Format | Interviews and recorded material |
|---|---|---|---|
| The Tinder Swindler | Women deceived by a man posing as a wealthy heir | Feature documentary film, released in 2022 | Victims recount their experiences; messages and other digital communications help trace the deception. |
| The Keepers | The 1969 murder of Sister Cathy Cesnik and related allegations | Seven-episode docuseries, released in 2017 | Former students and others give personal accounts, alongside archival material and investigation-focused reporting. |
| Making a Murderer | Steven Avery’s criminal cases and the legal proceedings around them | Two-season documentary series, released in 2015 and 2018 | Interviews and courtroom footage follow the cases, legal arguments and responses from people involved. |
| Don’t F**k with Cats: Hunting an Internet Killer | Online users’ efforts to identify a man who posted videos of animal abuse, followed by a murder investigation | Three-episode docuseries, released in 2019 | Online investigators describe their search; videos, screenshots and other digital material show how it developed. |
| American Murder: The Family Next Door | The 2018 murders of Shanann Watts and her daughters in Colorado | Feature documentary film, released in 2020 | Texts, social posts, home videos and police footage form much of the account, rather than conventional talking-head interviews. |
For a self-contained film, the two feature-length titles offer concentrated accounts; the series allow more time for investigations, testimony and legal developments to unfold.
Criteria for choosing a subject
Choose by the kind of evidence or storytelling that interests you most:
- Legal proceedings: Choose Making a Murderer if you want courtroom footage, competing legal arguments and developments spread across two seasons.
- Personal testimony: Choose The Keepers for accounts from former students and others connected to the investigation of Cesnik’s murder.
- Online investigation: Choose Don’t F**k with Cats if you are interested in how online users examine posts and digital clues before an official murder investigation.
- Digital records: Choose American Murder for a film shaped by texts, social posts, home video and police recordings.
- A contained film: Choose The Tinder Swindler or American Murder for a feature-length account rather than a story extended over several episodes.
For a single sitting, a feature film is the practical fit; for a closer look at testimony, online searches or legal proceedings, choose the series whose subject matches that interest.
