Lititz Borough Police Det. John Schofield said Heist expressed shame and apologized for what she did to her family.

"She has a birth certificate and a death certificate so she's got a long ways to make this right again," Schofield said. "She's got to take it slow with her family, I'm sure, and it's going to be a long process."

Schofield said Heist lived with a man in a camper in Key West for about seven years and worked odd jobs. Schofield said she never had access to a computer and never checked to see if she was being sought, although she assumed she was.

Heist remained in protective custody in the Keys, the sheriff's office said Wednesday.
