In the beginning of 2012 Forrester told Heist that she was moving in a different direction, and that she could no longer live with her. At that point, according to Forrester, Heist moved in first with Forrester's ex-husband and then with another family whose home she cleaned in Gulf Breeze, Fla.
"She lived there until very recently," Forrester said. "My ex-husband went to the house because her phone had been disconnected, and her Facebook had gone down. The gentleman at the house said he hadn't seen her in a few weeks."
What happened to Heist since then and her reemergence to authorities last Friday is not clear. Schofield said that when he met with her, her appearance was consistent with someone who had been living the homeless lifestyle, and she looked malnourished.
Heist's ex-husband, Lee Heist -- who was at one point a person of interest in her disappearance -- is now remarried and living in Montgomery County, Pa.
