My father is a sexual predator and I have come to the end of my rope with him. How do I evict him?

My father is 77 and mentally sound; ie. pays his own bills, drives, makes and keeps doctor appointments for himself and his dogs. I don’t get phone calls about him being lost or confused. He lives in his own double wide on my property adjacent to where my home is located.

Recently he has decided he is gay, but that's not the problem. However, he has had one of my son's friends (26 yr old male) come to help clean the yard and invited him in for a soda. Long story short, my father behaved in such a way that the young man did not become violent because it was his best friend's grandfather.

Fast forward 4 years. I have a young man (31) staying in my home who just got out of a mental hospital for schizophrenia (my best friend's son). He is on the shot and is getting his life together. My father was made aware of the situation and not to be alarmed by him walking in the yard talking to himself and such. I never thought about my father and his… whatever it is! I went to work to return home to this young man telling me how my father needed help with a shower. To spare the gory details, my father convinced him to let him use his phone to look at porn and touch himself in front of him. This young man said he was just trying to help an old man who was scared to fall in the shower. He ended with, “I took off my glasses so I didn’t have to see. To tell the truth I didn’t appreciate it very much. Do you have something to clean my phone with because I think it’s dirty now.”

My father told him not to tell anyone and he would go to the bank in the morning and get him $100. I am furious with my father. I told him so, I told him he had to leave. I called my aunt, who is POA, and she is no help. My father made out like it was innocent, then he tried to blame the young man, then he ended with he doesn’t remember what happened. He lies!

I called the sheriff's office and they suggested not to put the young man through this since he had a job interview and was moving into an apartment.

My husband thinks I should let it ride because my father is unstable. He will shoot guns out his back door (we live in the country). He feels he might just not care and try to hurt someone. My son refuses to speak to him. My son was the last family member beside my aunt who had any dealing with the man. My son wants him gone, evicted. My son and his pregnant wife were planning to move in at the end of this month. My husband and I are moving to another state to help his mother. So my son is taking care of things here and he no longer feels safe to have his family next door to a predator.

So really my question is: WHAT THE HELL DO I DO??? The law isn’t much help till he actually hurts someone. He is a master manipulator.
