What is the actual issue in reversing Roe v Wade? Is it murder? Help me out here.

In trying to do some research, the key phrase I come up with in articles about is "According to the opinion, abortion is “fundamentally different” because it destroys fetal life."
So, do they mean it's murder? Manslaughter? What would the actual crime be called?
The reason I ask is that there appears to be no statute of limitations on murder, and varying amounts of years for manslaughter, so can they go after women years after the "crime"? If they can, it's gonna be chaos, especially as people hopefully turn in all the fundamentalist females who had abortions. (I'm not saying that vindictively, I'm saying fair is fair.)
I really don't know any of the answers here, I've lived the last 50 years of my life not even ever having to wonder about it.
My heart goes out to all who will be affected by this.
