Abusive relationship???

My sister is in a very abusive relationship. The "boyfirend" has her scared to death to leave. He told her he would kill her the kids and extended family members. I have contacted different police agencies and they say there is nothing they can do until she comes forward. I have contacted Childrens Aid (CPS) and they lie through their teeth that nothing is wrong. My sister lies so she won't get a beating.
Regularly they are fighting and she screams for help but no neighbors will call the police. The "boyfriend" has destroyed the house phones so neither my sister or her oldest child could call the police.
He has destroyed most of her clothes, anything my parents have bought the kids. He is destroying her and the childrens lives.
Is there anything that could be done to make this guy stop what he is doing and pay for these crimes?
My sister says she won't be at peace until he is dead.
Is killing someone from self defence like killing someone on purpose?

I jump everytime the phone rings thinking it is my mom calling to say she or the children have been seriously hurt or worse....

Time to move and hide this family. The only reason he is alive today, because it's against the Law to kill him. Don't take his threats lightly. He could carry out his plan and kill the most important things to your sisters life. Also go to his family and tell them, their son needs to be committed. To kill someone in self defense, is a hard thing to prove. Many women have killed their husbands claiming it was self defense, only to be found guilty, after major investigations. Poor Children, they don't deserve this. Good Luck and I will Pray for your Sister and her Family. Also Pray for the troubled Man, that he may be healed and become a good person.

It's not self-defense if he hasn't done anything to warrant being killed (like assault in progress). I would call the police and file a report about the "he would kill her, the kids, and extended family members" and that oughta get a nice surveillance and investigation going on. Bottom line: Call the police (non-emergency number unless it's a real emergency) and tell them what's going on.

If she shoots and kills this guy while he is beating her then no charges will be brought against her because it would be self defense and beaten wife syndrome. In this case she should just leave him and NOT bring a gun into the house he may use it on her. The best thing to do is ship her and the kids out of state and every one else get an order of protection against him.

Dont kill this man unless its from self defence, what i suggest is that you take your sister and her children away to your house, a friends house, mothers house, any where that isnt where that guy is, and try to convince your sister that she should contact the police herself about this, maybe file a restraining order, or a law suit to get him in jail, anything that may get her and him farther apart, i hope this helps

The mission that I support has a program to hide them, and then get them back on their feet. It depends where you live. We helped a family from North Carolina escape up north, paid for their housing, food, and helped relocate them. That was a very extreme case. Do you know anyone on the Force?

It is legal to use deadly force to protect yourself or someone else ONLY when the danger is IMMEDIATE.

Yes - you can report the domestic violence.
Even if they lie when the Police come, if there are any signs of abuse, the Police are mandated to arrest him.
In answer to your other question; if you kill someone in self defense, especially after suffering abuse from them, it is definitely NOT the same as murdering them.
You need to get your sister and those kids out of that house and into a domestic violense "safe house." Even if they have to leave all of their belongings behind, it is better than them being killed by this person.
Domestic violence is a cycle of abuse that only ends in one of two ways. The incarceration of the abuser or the death of either the abuser or the victim.

Get her out of there as soon as you can.

If there are witnesses, the police have a duty to arrest the individual for domestic violence, assault, battery, assault with intent.
The best thing would be to contact the police, if they won't do anything file a complaint with the police complaint center. www.policeabuse.org.
Contact the State police. FBI Highway patrol, or any outside law enforcement agency,
if she kills him, she could be charged with premeditated murder. because she has thought about it in advance.
If your sister won't go to the police, she may indeed end up dead from his violence, Its time she looked fear in the eyes and turned it back on him in the legal way
Hope this helps
