What is the statute of limitations on suing a nursing home for elder abuse, neglect, and violating a medical power of attorney?

Hello it's been a while since I've posted in this form. The last time I posted, I was very irate at a nursing home/rehabilitation facility. And to refresh your memory, it was because the nursing home did not fully explain with a DNR meant. DNR do not resuscitate is a very cruel thing. after a certain point they will take all your medications away. If you are in medicine, and they will not give you any more food. My mother, because of this, died in an anorexic state. Now, she did not have a feeding tube because she did not want one after I explained to her what a full code was. And what a full code is it means, that if you pass away. They were resuscitate you and they will hook a feeding tube up to you. My mother did not want to live on machines. So she told me to tell them that she did not want the full code. Mind you, she had just had brain surgery. And there were a lot of confusing things that were going on at the time. Well, they had convinced her to get a full code. But, at that point she did not know what a full code was there were so many people in the room that it confused her. We did check in to get an attorney, and most of them wanted money up front one said $7000. The other one said $5000 and the other ones were between $3000 and $4000 and we don't have that kind of money to sue a nursing home. My cousin is known attorney and he said he would take the case, but it's been almost 3 years. Is it too late under the statue of limitations to sue the nursing home that was responsible for my mother's death? If anybody has the answer to this. Please make sure that you let me know because we do intend on taking a case against the people that were at fault for the nursing home neglect. Now, I don't know if we have to sue each person, or if we have to go after the nursing home in court? Because, there was a lot of neglect not only in explaining what a full code was but basically, for starving my mother to death. I know she had a brain tumor which was a glioblastoma and that would have taken her life. But, I had the full medical power of attorney and I had told them that I wanted my mother to go to the hospital and they wouldn't do it. I did sign a piece of paper giving some of the rights to hospice, but I am unsure of whether we have to go after the nursing home, or hospice themselves. If we have to go after hospice, I will do that. But, I still want to hold people responsible for the nursing home neglect. Because they did not only neglect her by taking her food and her medicine away. But, they neglected her because a lot of times when she had to go to the bathroom. Nobody would come to the room for at least an hour and a half and she ended up messing herself several times because of this. There were only three or four people that were over at the nursing home/rehabilitation center that did their jobs correctly. Sometimes. But most of the people did not do their jobs correctly and were neglectful to my mother. If we do go after this place. It's called Genesis healthcare and it was called "the Butte Center"that was connected with Genesis healthcare. I know people are praising nursing homes and hospitals at the moment. But, in this situation. They don't deserve to be praised. So, if you know what the statue of limitations on this is please, make sure to let me know so me and my siblings can get our lawsuit started on this place. I am also writing a book called " the dangers of hospitals and nursing homes" I want to expose these people for the kind of tyrants that they are. For example, there was a man that was over at this facility and when I let him know that I was coming for all my mother's records. He quit the very next day: so, sounds like he got scared and ran. The nurse that was also responsible for the neglect got fired and it's a good thing she did. I talked to another resident that was in distress at that facility and was told to shut up and also got slapped by this nurse....
