According to Human Rights Watch, it’s estimated that about 90 per cent of crimes in Mexico are never reported, while a third of reported crimes are never investigated. About 2,600 foreigners have gone missing in Mexico in the past 15 years.

In this episode of the True Crime Society Podcast, we discuss two separate cases of foreigners who have gone missing in Mexico.

  • Canadian man Malcom Madsen was a snowbird who enjoyed traveling to Mexico every year.  Malcolm purchased a home near Puerto Vallarta for his girlfriend Marcela Acosta.  In 2018, the couple were seen on CCTV enjoying a night out at a local bar.   Marcela could be seen putting a substance into Malcom’s drink.  Minutes later, they left the bar and Malcom was unsteady on his feet.   He has not been seen since.  Marcela and two accomplices have been sentenced to over 50 years in prison in relation to Malcom’s disappearance.
  • Australian woman Tahnee Shanks had been living in Mexico for years in 2022.   She and her husband Jorge had been having marriage problems, and she planned to return to Australia with their daughter Adelynn.  The family decided to take one last vacation together.  In May 2022, Adelynn was found wandering alone and barefoot outside a church in Cancun.   Now, almost three years later, both Tahnee and Jorge remain missing.  Is Jorge on the run after killing Tahnee or could they both have been murdered by the Mexican cartel?
