Crime Stories with Nancy Grace.

Jenny Carreri never lost her drive to find the killer of her twin sister, Jody Lacornou.

The sisters shared a bond that began in their mother's wound, twins, or in two minutes apart.

Jenny came up with a unique way to generate new leads in this cold case. A larger than life billboard

Lots of mixed emotions over the years, you know, sadness, frustration, anger.

Jenny says she knows the first face her sister saw when she was born. She wants to know the last

face she saw when she died. You're hearing our friend, David Collins at WBAL NBC 11.
