Show Notes

November 8, 2025, a small SUV drives up to the Carnival cruise ship docked at Port Miami. The thick letters on the side of the car read:

MIAMI DADE COUNTY
MEDICAL EXAMINER

FBI agents are seen bringing what appears to be a cadaver stretcher off the ship.

Just 24 hours before docking, in a cabin where three step-siblings were rooming together, a crew member finds a dead body.

An 18 year old girl named Anna Kepner, hidden underneath a mattress amongst blankets and life jackets.

The youngest sibling is seemingly ruled out and the most likely person of interest appears to be her 16 year old step brother...Whom Anna’s father and stepmother seem to be defensively ‘protective’ of.

This is the ongoing case of Anna Kepner’s murder.
