I think that my stepdaughter is a psychopath.  She is 10 years old.  Her mom died shortly after birth.  She turned evil about 3 years ago.  Lies about everything, blames everybody else for everything that occurs, has no concern for others, manipulates to no end.  Here are the big ones.  Told my 6 month old baby that maybe (name) will have an accident and die and then I will be your mommy.  Jumped on her bed because her 7 year old brother was under it.  He was scared to death and when confronted about what if he had gotten hurt  "well I would have gotten in trouble".  No concern that she could have killed or hurt him.  She called maternal gps (who are a major pain in the butt-they have court ordered visitation and I am sure put stuff in her head)that I was beating her-Spanked her on butt with open hand with fathers permission-I had children's services and the police at the front door.  No care that that isn't what happened.  Did it to get me in trouble.  Doesn't want to live here wants to live with maternal gps.  Father absolutely against it because they are a different breed of people, yet he married their daughter.  Has no friends because is very bossy.  She has stolen from us.  Has no emotion what so ever and has a dead look in her eyes.  She was put in a partial hospitalization program in the fall for the two incidents involving her half brothers.  She was to be released from it on Monday and on Sunday she threw dirt balls at the neighbors school bus.  I called the police hoping they would do something and they wouldn't.  She got the 7 year old involved in that as well.  she showed no remorse to the police officer which he also noticed.  She said that she will do whatever she has to do to get out of our home.  Then her dad talks to her and the next day she wants to stay here.  she was put on meds because of the bus incident and her father took her off of them after about a month.  He is in denial.  I think that she has serios problems and if I had my way she would not be in my home.  He is taking her to the pediatrician at the end of the month.  She has not hurt any animals that we know of.  She has no respect for other people or their property and my biggest complaint is that she lies 99.99% of the time.  Please adivise me.  Sorry so long and thanks in advance for your opinions.
