Alexis Manigo drew national headlines when news broke that she had been kidnapped as a newborn, only to be found 18 years later.
On Thursday, ABC News obtained court records showing Manigo knew she had been abducted.
Two tips to the Jacksonville Sheriff's Office showed Manigo had been told by a friend she was a missing person, and that Gloria Williams confessed to stealing her from the hospital when she was a baby.
I understand what she did was wrong, but just don't lock her up and throw away the key. I still think of her as 'mom.'
Manigo reunited with her biological family last week. In an interview on "Good Morning America," Manigo said the reunion was bittersweet but that Williams was a "great mother."
Manigo, initially Kamiyah Mobley, was allegedly stolen by Williams, 51, who posed as a healthcare worker in 1998 and stole her from the University of Florida Health Jacksonville hospital.
At the time of the abduction, nurses thought that the kidnapper was a member of the Mobley family because they saw the suspect interacting with the family.
Surveillance would prove too grainy to ultimately identify the kidnapper. A broken camera in the nursery brought the case to a standstill.
The case eventually made its way on 'America's Most Wanted' with a $250,000 reward.
