A former US Homeland Security agent details years undercover tracking child abusers on the dark web, revealing the emotional toll and rescue cases.

A veteran US investigator has shared an inside look at years spent undercover on the dark web tracking child sexual abusers, revealing both the impactful results and severe personal cost of this specialised work.
Greg Squire, a former agent with the US Department of Homeland Security, describes how he transitioned from civilian life into digital child protection work after viewing evidence of abuse early in his career. As the volume and sophistication of illegal content on hidden internet networks increased, Squire and a small international team focused on infiltrating paedophile forums and identifying offenders.
Many cases involved painstaking investigation and collaboration across agencies, including high-profile rescues documented in the BBC documentary “The Darkest Web”. One notable operation helped locate a child identified only as “Lucy” by analysing environmental clues within dark web content and tracing geographic indicators.
Squire says the work required long hours in highly disturbing environments, with exposure to graphic material contributing to emotional strain. He likens the toll to “drinking poison,” describing battles with alcohol and psychological pressure that ultimately required therapy and strong personal support systems.
The investigation team’s efforts reflect ongoing challenges in combating the exploitation of children online. Squire emphasises the need for increased public awareness, sustained resources for law enforcement and mental health support for specialists in the field. Despite the difficulty, he says that persistent vigilance and coordinated action can make a meaningful difference in protecting vulnerable victims.
