Here in Michigan many years ago, an island in the north was used for pedophiles. Boys were taken there from very poor areas of Detroit to go camping, then molested by wealthy men who flew to MI from all over the world, then flew one small plane to the island.
When it was all discovered the records for who flew on that one small plane just disappeared. The Traverse City Record did great work on this story.
Additionally there was a child serial killer in Oakland County, outside of Detroit in oh the 60s I think.
Children were kept alive, raped for days and then killed they think with vet anesthesia meds. So incredibly cruel!!!
Paralyzed until they suffocated.
But again ,corruption and evil won, records were changed and things disapoeared.
A great book on this is called The Kill Jar.
The levels of evil, lies, and years of public deception took my breath away. I was a child in Detroit in those years but in a less wealthy area.
I don’t know what it takes for things to stop disappearing, but it happens quite often.
Here in MI as well, sure hope that story is an urban legend...
