My Dad is taking care of my Mom who has terminal cancer. He has been getting frustrated and depressed because he is tired and needs help. My sister and I have tried to hire nurses to come in twice a day but they fired them. Mom has home health three to four times a week. My sister comes in a lot during the week and I am paying for a housekeeper. I am concerend he will snap when my Mother passes. Is there any legal way to get the guns out of the house?
