Wow. Intense. Probably got a hefty fine and probation (presuming no other issues with the law).
But here is the Florida Statute 379-2431 subsection something or other (presumung they were in Florida)......
A person, firm, or corporation that illegally possesses any marine turtle species or hatchling, or parts thereof, or the nest of any marine turtle species described in this subsection, commits a felony of the third degree, punishable as provided in s. 775.082, s. 775.083, or s. 775.084.
Since they traveled over State lines, it became Federal (pretty sure).
