3. 'We Call It Life Row': Two of the Youngest US Women on Death Row Describe Life Behind Bars

When Tiffany Cole and Emilia Carr walk down the hall in Florida’s Lowell Correctional Institution for Women together, they seem more like smiling girlfriends than convicted felons sitting on death row.

Cole is now 33, and Carr is now 30. Carr is the youngest woman in the United States sitting on death row, and Cole is the third youngest. The two women are behind bars for committing two separate crimes, and they had separate lives until they arrived as neighbors on the famous death row corridor at the women’s correctional facility in Ocala, Florida.
