Jennifer Marteliz was seven years old when she disappeared while walking home from school in Tampa, Florida, on November 15, 1982. She was only blocks from home. Witnesses later described seeing Jennifer upset near a crossing guard and possibly near a rust-colored car shortly before she vanished. What should have been an ordinary walk home became one of Florida's most haunting unsolved child disappearance cases.

In Episode 3 of SEQUESTERED Season Four, Sara Reid reconstructs Jennifer's final known moments through witness accounts, search records, media reporting, and the growing fractures inside the investigation itself. As police and volunteers searched neighborhoods, drainage pipes, vacant lots, and wooded areas across Tampa, the case slowly became defined by uncertainty: conflicting sightings, theories that never fully fit, and a timeline that seemed impossibly small for a child to disappear without a trace.

More than forty years later, Jennifer Marteliz has never been found. And the few minutes between school and home still remain unexplained.
