There was a case like that here in my area early this year.In June a woman went missing leaving her 2 year old son home alone.She was 8 months pregnant.Her name was Jesse Davis.Her baby was a little girl.I forget what her name was going to be.Cloe I think.
Two weeks later her body was found in a national park a few miles from her home.Her boyfriend and a friend of his were arrested.He was charged with 2 counts of murder and the friend with abuse of a corpse x 2.He was a cop.
In Ohio if you kill a pregnant woman and the fetus dies or you kill her fetus and the mother lives it's murder.Doesn't matter if the child was born alive or not.Doesn't matter if the child could have lived or not it's murder.Also if a pregnant woman takes drugs while pregnant she can be charged with child abuse.
