T02:C11 - S02:E11 - Family Secrets

A young mother and her infant son mysteriously disappeared from their home. The woman's husband was the only suspect, but he was eventually cleared. There was no solid evidence that a crime had even been committed. Six months later, a local farmer found the remains of the missing woman and her child. Both had been murdered. Agents and local police had only one tiny piece of evidence, an unidentified hair found in the murdered woman's car. The hair was too small for analysis.
