If you go down to the woods, tonight...don't let a strange man tie you to a tree, even if he does offer you two hundred bucks. Yes, you boy!
This documentary about sicko Daniel Conahan has it all. It begins with a dog finding bones in the woods. Its owners aren't the slightest bit suspicious until one day it brings home a bone that obviously does not belong to a deer or some such.
The documentary makers speak to Susan Brown who sounded mildly amused that she was transiently a murder suspect. Sadly, there turns out to be more than one body, and the men on the trail of a certain serial killer get a lucky break when a man in an orange suit tells them an implausible story about how he came to steal a car. The dude who reported it missing had been driving him to the woods for an ostensible photoshoot of him tied naked to a tree when Fate intervened as only it can.
This gave detectives a name. Anxious to arrest Conahan before he could claim anymore victims, they engaged in a stake-out. The documentary makers speak to the officer Conahan picked up in a public toilet. There is also actual footage of him being questioned in an hotel room rather than a police station, and a lot more.
At the end of the day, although he was charged with and convicted of only one murder, which earned him a death sentence, he is believed to have committed at least another fifteen. Although he was convicted in 1999, at the time of writing he has still not been executed.
