I don't know how much it costs David emotionally to invest so deeply in each case, but it shines through the episodes. I hope Trevor and his Dad find the answers they deserve. Thanks for letting us come along with you.

David treats each case with care and sensitivity. This is not exploitative or ghoulish. He really wants to find answers for the families and it seems he forms good relationships with them.

Introducing: The Flamethrowers
The Flamethrowers captures the punch-you-in-the-mouth energy and sound of right-wing talk radio. Host Justin Ling takes us from the fringe preachers and conspiracy peddlers of the 1920s to the political firestorm that rages today. With humour and candour, Ling examines the appeal of broadcasters like Rush Limbaugh, who found a sleeping audience, radicalized it, and became an accidental kingmaker — culminating in the election of Donald Trump.
