Intro

Police believe someone broke into their home that night and a fire was started, but no-one has ever been charged.

With claims of evidence compromised, mistakes made and missed opportunities. We turn our attention to the crime scene forensics.

Hear from people closest to the case, speaking for the first time about their concerns.
