Allegations of a forced confession, manipulated evidence fuel Illinois day care worker's push for clemency

Melissa Calusinski has served 16 years of a 31-year prison sentence for the death of Benjamin Kingan, a 16-month-old whom she cared for at an Illinois day care center. She has long insisted she is innocent.

"This is not where I belong," Calusinski told "48 Hours" correspondent Erin Moriarty. "I'm gonna continue to fight no matter what 'cause I did not do this."

"48 Hours" has been covering this case for more than a decade, and over the years, Melissa's appeals have failed. But she and her attorney, Kathleen Zellner, are not backing down. Now, they are taking their fight out of the court system and straight to the governor of Illinois, J.B. Pritzker, and his prisoner review board.
