Still a Mystery

Still a Mystery is an Investigation Discovery series that does exactly what cold case coverage should do — it goes back in. Premiering in March 2018 and running for six seasons through to 2023, each episode takes a single unresolved crime and asks the questions that were never properly answered.

Marshal Iwaasa's burned-out truck, found on a remote logging road near Pemberton, BC — the last physical trace of his disappearance in November 2019.

The format is straightforward but effective. Was it suicide or murder? A runaway or a kidnapping? Accidental or premeditated? Through interviews with law enforcement, family members, and private investigators — alongside news footage and social media — the show builds a forensic case for why the official verdict may not be the whole story.

What sets it apart from the crowded true crime field is that focus on the single case per episode. There's no rush to move on. The show sits with the ambiguity, and that patience is what gives it its weight. For the families involved, these aren't cold cases at all — they're open wounds. Still a Mystery treats them as such, and that's what keeps it compelling across six seasons.

An Investigation Discovery series re-examining unsolved and disputed cases, one at a time.

Delgaty Picture Post handled the colour grading, finishing and broadcast delivery for season 7.
