A 23-year-old Austin, Texas man was arrested at Miami International Airport on March 7, 2026, while trying to board a flight to London’s Heathrow with nearly 75 pounds of marijuana hidden in his checked luggage. U.S. Customs and Border Protection officers flagged him amid heightened outbound narcotics smuggling checks.
Bust Details
Harrison Oneill Tiernan was questioned about his bags, which contained 65 vacuum-sealed packages of a green leafy substance later confirmed as marijuana. The discovery stemmed from routine inspections targeting high trends in drugs leaving the U.S.
Charges and Aftermath
Tiernan faces a Florida state charge of cannabis trafficking for 25 to 2,000 pounds, booked into Miami-Dade’s Metro West Detention Center. Federal authorities reviewed but declined prosecution due to insufficient quantity threshold, handing it to the Miami-Dade Sheriff’s Office. Jail records confirm his custody status.
