( CNN ) -- Though her mother has suddenly reappeared after 11 years , do n't expect a family reunion any time soon , Morgan Heist says . `` I do n't think she deserves to see me , '' the 20-year-old told CNN 's Piers Morgan on Thursday night . `` I do n't really have any plans on going to see her . '' Anger is one of the many emotions Morgan Heist has gone through since she learned last week that Brenda Heist , the mother she last saw when she was 8 , had mysteriously reappeared . Brenda Heist disappeared from her Pennsylvania family some 11 years ago , leaving her husband , daughter and son wondering if something terrible had happened to her . Police searched for her for years , even at one point creating a cold case task force . Then last week Brenda Heist , 54 , turned herself in to authorities in Key Largo , Florida , saying she had just walked away from her family because of stress . The fact that her mother abandoned her and never even called has left her seething , Morgan Heist said . The anger is captured in a post on the daughter 's Twitter page that reads she hopes her mother `` rots in hell . '' `` That makes me really mad , '' Morgan Heist said . `` I ca n't believe she would do that because she was a good mom . She was great . But , I mean , I guess something happened . Something snapped in her. `` Her father , Lee Heist , said he is not planning on visiting his former wife anytime soon . `` I do n't see where it would do any good for either of us to see her again , '' Lee Heist said . Left on a whim . Brenda Heist disappeared February 2002 after last being seen dropping off her children at school . She was going through a divorce from Lee Heist and was applying for housing assistance so that she could get an apartment . She worked as a bookkeeper for a car dealer and hoped to receive some financial aid . However , her request was denied , police said . `` She was very upset , she was sitting in a park crying , thinking about how she would raise her children , feeling sorry for herself , '' said Sgt . John Schofield , a Lititz Borough , Pennsylvania , police detective . Schofield was one of the many officers who searched for Heist . It was n't long before she was approached by two males and a female who asked her what was wrong . After she told them what had happened , they invited her to hitchhike with them down to Florida . `` At a whim , she decided at that very moment , she would go along with them , '' Schofield said . Schofield spoke to Heist at length after she turned herself in . `` She was very emotional ; she hung her head ; she 's ashamed . She was crying when I met with her . She knows what she did was completely wrong , but all that while , she 'd never made one effort to call or contact her family at all , '' Schofield said . Years homeless while husband under suspicion . She spent the first two years homeless , living under bridges , eating food thrown out by restaurants after they closed . For the next seven years , she lived in a camper with a man she had met . They made money as day laborers , cleaning boats and doing other odd jobs for which they did n't have to show ID and were paid in cash . After that relationship soured , Schofield said , she lived on the street again for another two years . Lee Heist even became a suspect though he was eventually cleared . Some believed he was involved in Brenda Heist 's disappearance , he said . `` The hardest thing I had to deal with was , the families of some of my children 's friends would not let them play with them , because of what they thought of me . That just tore me apart . I hope they 've learned a lesson not to prejudge , '' he said . In 2010 , Lee Heist filed a petition with the county court to have Brenda declared legally deceased , according to a Lititz police news release . It was a measure necessary for closure , he said . Lee Heist later remarried and said he will learn to forgive his former wife . But for Morgan Heist , forgiving her mom may not be easy . `` I hope to eventually forgive her one day for myself , not for her , '' Morgan Heist said . CNN 's Laura Ly contributed to this report .
