The 33-year-old Ontario woman’s painstaking digging uncovered the fact that key evidence had been tampered with, in a legal ordeal that kept her and her airline crew trapped in the Dominican Republic for more than seven months.The nightmare began on April 5, 2022, when the Pivot Airlines crew was making final preparations to return seven Canadian passengers on a chartered flight from Punta Cana to Toronto.The passengers disembarked and headed to a VIP lounge while Christina and the rest of the crew stayed on the tarmac.They watched in horror as a big black duffle bag, tied up in yellow rope, was removed from the plane’s avionics bay -- a compartment under the plane that houses the computer systems.For the first time, Carello is telling the story of how she discovered that someone had tampered with airport surveillance video taken the night before the drugs were found."
