Abi describes the eerie goings-on that led up to the heinous murders of six family members living on their quiet farm northeast of Munich in Bavaria, Germany. There's is a strong possibility the assailant stayed four days after committing the murders, tending the animals and fixing meals. The murders went unsolved until a 2007 investigation where a possible suspect has been kept secret to this day.

 The episode comes to a close with talk of the U.S. inauguration, the frustration with social media and politics, controversial opinions on the cartel, and how Abi would hope to be recovered should she ever go missing.
