In this episode of The Crime Scene Insiders, we sit down with expert investigator and diving specialist Peter Faulding, Founder of Specialist Group International (SGI). Peter shares his remarkable journey — from early careers in emergency response to becoming a leading voice in underwater search and recovery operations.

We dive into the technology behind Peter’s work, the hidden challenges of interpreting sonar, and some of his most notable cases.

We then turn to the high-profile Nicola Bulley case — discussing the sonar footage released by SGI, the collaboration and challenges between private search teams and police, and the College of Policing review into how the investigation was handled. Peter speaks candidly about his role, the public scrutiny, and what accountability means in forensic search and major investigations.
