Abused friend wants to remove parents as beneficiary when she escapes

I live in the state of New York. I have a wonderful friend (25F) who has been refused freedom of movement, medical care, and sometimes food by parents who would not allow her to have her own bank account or learn to drive despite being in her twenties. She is also not to leave the house without permission. She is terrified of her controlling, mean-spirited parents and in particular her violent alcoholic father. And finally she feels ready to leave. We are helping her square away all the little details and making plans to get her out while they are working.

One fear that she has brought up is that her grandfather bought a life insurance policy on her when she was born. She believes her parents took over the policy and continued to pay into it after her grandfather’s death. Her mother drains her bank account on occasion, as the father is often unemployed. My friend believes that the resultant financial desperation of her cutting them out of her life may lead them to attempt to kill her for the insurance money. Now, I know it would be a long shot of them getting away with it, but these people are maybe just stupid enough to try. So is there a way to remove the temptation, so to speak? Can you change the beneficiary or even cancel a life insurance policy you didn’t open if it is on yourself?
