Missing in Mexico | Malcom Madsen & Tahnee Shanks

Timestamp to skip the intro and get straight to the case: (10:11) 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?

Timestamps: (5:50) - Tracey Nix Update (10:44) - Amy Lynn Bradley In March 1998, Amy Bradley boarded a Royal Caribbean cruise with her brother, mother and father, looking forward to some fun in the sun. The family enjoyed seeing Aruba and taking advantage of all that the ship had to offer including restaurants, bars and nightclubs. One night on their cruise, Amy and her brother Brad danced until the early morning hours at the nightclub on the ship. They went back to their cabin and Amy was seen asleep by her father just after 5am. When he woke up again at 6am, Amy was gone.   27 years later, Amy remains missing. The investigation into her disappearance has been criticized by her family as Royal Caribbean did not want to alarm other passengers on board.    Over the years, there have been many reported sightings of Amy and it is feared that she has been trafficked and is being forced to work in the sex industry. Was Amy abducted and smuggled off the ship?  Could she still be alive? Or did she fall overboard and drown?

Timestamp to skip intro: (8:45) In 2019, Evelyn Boswell (15 months) was seen alive for the last time, reportedly by a babysitter in Blountville, Tennessee. Evelyn was not reported missing until February 2020.   Her grandfather raised the alarm after he said he had not seen the child since Thanksgiving. Authorities started investigating and zeroed in on Evelyn’s mother, Megan ‘Maggie’ Boswell.   Megan gave varying accounts of where the child was and repeatedly lied to law enforcement. In March 2020, Evelyn’s tiny body was found with her head wrapped in aluminum foil.   She had been stuffed into a trash can and discarded like waste. Megan would be arrested and charged with Evelyn’s murder.   Now, five years later, Megan’s trial has just concluded and she has been found guilty of killing her daughter.  Read our blog for this case Be sure to follow us on Instagram for the latest crime news Join us on Patreon for exclusive, ad-free content This episode is sponsored by: Cure Hydration:  The electrolyte drink mix that tastes as amazing as it makes you feel.  Cure is offering 20% off your first order!

Timestamps: (7:57) - Poisoning Cases In this episode of the True Crime Society Podcast, we discuss two cases where men were possibly drugged to death by women. Sports reporter Adan Manzano (27)  was found dead with no signs of trauma in his New Orleans hotel room in February 2025.  Adan had been in the city to cover the upcoming Super Bowl.  When police began investigating, they discovered Adan was last seen with a female ‘career criminal,'  Danette Colbert.   Danette has a history of drugging and robbing men. It was discovered that Danette used Adan’s credit card after his death. His cause of death is still pending with the Medical Examiner. Indiana man Harold Allen died in 2022 from what was initially thought to be natural causes.  It was only after his step-daughter, Ashley Jones, staged a robbery that his death was investigated.   It came to light that Harold was likely poisoned to death with ethylene glycol by his wife Marsha and Ashley.  The women tried multiple times to kill Harold with varying substances before they were successful. After Marsha was questioned by police, she took her own life. Ashley is currently awaiting trial.   Read our blogs for these cases: Adan Manzano Harold Allen Podcast Recommendation: Looking for a podcast that’s unfiltered, hilarious, and totally unpredictable?
