Detective, I beg you, find my son Nathan! His father, Marc, is a violent, paranoid, and unstable man. He snatched him from outside the school this afternoon. He lives like a savage on a rusted barge, 'The Blue Heron'. The police are too slow; they refuse to issue an Amber Alert because he has parental authority! Marc has completely lost his mind, accusing me of the worst atrocities. Find that boat before he hurts my baby. I'll pay you whatever you want, but please hurry.
