Can I have my grandmother's husband arrested for abuse?

My grandmother has been very ill, and her husband refuses to assist her, will not bring her food/drink, won't respond when she calls for him. Recently, my mother went to their house and found my grandmother laying in bed, in her own feces, with a 103 temperature, moaning in pain. Her husband wouldn't allow my mother in the house at first, she had to shove him out of the way. He later raised his fist to my mother. An ambulance was called, my mother invoked her proxy and had my grandmother taken to the hospital, where they found she had a very bad urinary tract infection. Can my grandmother's husband be arrested on charges of abuse/neglect?
