Mystery in Mexico

When a two-year-old toddler, all alone but seemingly unconcerned, walked bare-footed into a church in Cancun, Mexico four weeks ago, kind-hearted locals rushed to help. First they needed to work out who she was and then who she belonged to. The child was too young to talk, so her photograph was shared on social media. It was a strategy that worked, but the answer surprised everyone. The toddler's name was Adelynn, and she was the daughter of a Queensland woman, Tahnee Shanks. One mystery had been solved, but it led to another one. There was no trace of Tahnee or Addy's father, a local man, Jorge Aguirre Estudillo. As Tara Brown reports, a major police investigation is now underway to find the couple. But in a country gripped by cartel-related violence, there are fears it could already be too late.
