She left behind a daughter who was just three at the time. Every year on the anniversary of Hammel's disappearance, her family makes the long trip from New Jersey to Houston, hoping to keep the case alive.
"Somebody knows what happened to my daughter, somebody is watching this on TV right now and is looking me in the face and knows that we are looking for you and it is time you come clean," said Hammel's mother Catherine Henderson.
