Netflix will premiere The Investigation of Lucy Letby on February 4, 2026, delivering what the platform describes as the most comprehensive examination of the case to date. Directed by Dominic Sivyer, the feature-length documentary examines the crimes of Lucy Letby, a neonatal nurse at Countess of Chester Hospital who was convicted of murdering seven babies between June 2015 and June 2016.

Letby was found guilty of seven counts of murder and seven counts of attempted murder in 2024. She is currently serving 15 whole-life orders, meaning she will never be released from prison. The case gripped Britain and sparked widespread discussions about healthcare safety, institutional accountability, and how such crimes could occur within a hospital setting.

The documentary stands out for its exclusive access and never-before-seen material. It includes footage from Letby's arrest and subsequent police questioning—content that has not been publicly available until now. This intimate look at the investigation's critical early moments provides viewers with direct insight into how authorities approached one of the most serious criminal investigations in recent British healthcare history.

Among the documentary's most significant contributions is testimony from a victim's mother. This marks the first time a prosecution family member has participated in documentary format to discuss the case, offering a deeply personal perspective on how the crimes affected those closest to the victims. Their involvement adds an emotional and human dimension to the investigation's procedural elements.

The film also features interviews with the British police officers who led the investigation into Letby's conduct. Their accounts provide professional insight into the challenges of investigating crimes within a medical setting, where perpetrators exploit positions of trust and access to vulnerable patients.

To ensure comprehensive coverage, the documentary includes perspectives from both sides of the case. Lawyers representing both the prosecution and defense contribute their expertise, offering legal analysis and context for how the evidence was presented, challenged, and ultimately determined in court.

Additional commentary comes from experts in relevant fields, helping viewers understand the broader implications of the case for healthcare systems, criminal investigation procedures, and institutional oversight.

The release of this documentary comes as public interest in the Lucy Letby case remains high. The conviction raised serious questions about how a healthcare professional could carry out such crimes over an extended period, and what institutional failures allowed the situation to persist. The case also sparked inquiries into hospital safety protocols and staff monitoring procedures.

For an international audience, the documentary provides context on the British healthcare system and how such a case moved through the UK criminal justice system. The detailed examination helps explain not only what happened, but how the investigation unfolded and why it took considerable time to build the case against Letby.

The Investigation of Lucy Letby will be available exclusively on Netflix from February 4, 2026, making it accessible to viewers worldwide. The documentary's release represents Netflix's continued investment in high-profile true crime content that examines significant criminal cases with depth and detail.
