Dana Walsh was a senior data analyst at CTU New York. She was engaged to the director of field operations at CTU New York, Cole Ortiz. Dana had a hidden past with another name - Jenny Scott.

Day 8
After working with fellow CTU personnel to avert a terrorist crisis, Dana received a threatening call in which Kevin Wade referred her as Jenny from Rock Springs 5:29PM. Walsh was periodically harassed by Wade over the phone until he finally showed up at CTU. There, he interrogated and blackmailed her to give him a place to stay; if she refused, he would reveal troubling secrets about her past.
He later revealed over the phone that Dana was an ex convict and was involved in a car robbery murder as a juvenile. Kevin Wade thought she had testified against him since she got out of jail before Kevin.
