My son takes nothing seriously

My oldest son (11) has been accused by my daughter (8) of showing her porn and trying to get her to give him a bj. The police are involved and he will likely be charged by the ada. He has to go stay with his dad for the time being.Since this situation developed about a week ago, my son has continued to act as though nothing has happened. He got in trouble at school. He ignored his responsibilities. He goofs off and laughs. I am sick and can't even eat. His stepdad and I are keeping him for the weekend so his dad can have time with his sister before he has to go stay with his dad.I just don't know how to make him see that this is serious. Is he a sociopath because he feels no remorse about the situation? Or, because he maintains his innocence, is it just because he doesn't want to make himself seem guilty?I'm so worried. I'm worried for my daughter if he did do it. She will be having therapy for quite some time. I'm worried for my son if he did do it and the type of person he is becoming. I'm worried for both of them if it didn't happen. Why would my daughter lie? What will this do to my son?This is awful. Thoughts? Anyone ever been in a similar situation? How do I be a good parent to both of them?TL:DR. Son accused of attempting to molest daughter. Police involved and charges possibly pending. He seems unaffected. How do I be a good parent to both of them? via /r/Parenting http://ift.tt/2dfTcOR
