DDD: Folie à Deux -- Three Cases of Shared Delusions
Show Notes

There are countless examples in true crime of the psychiatric phenomenon Folie à Deux, also known as shared delusion or shared psychosis. In this short episode, Allison goes into three very distinct cases.

In 2016, an Australian family, the Tromps, took an extremely bizarre impromptu road trip that ended with all of them separated and in various states of mental agitation and catatonia.

In the late 1970s, two men were incarcerated together and spent all their spare time feeding a shared fantasy of raping young girls. Once paroled, they set about putting their plans to work. Only it soon escalated to murder. Eventually becoming known as the Toolbox Killers, Lawrence Bittaker and Roy Norris were eventually arrested, but not before raping, maiming, and killing upwards of a half dozen young women and girls.

Finally, learn about Mr and Mrs A, a couple who became entrapped in one of the partners' psychotic states, feeding a series of delusions that eventually led to the death of their infant son.
