This can be simply resolved. All pregnancies are presumed to be intended. If a woman or a girl if under age claims the pregnancy is the result of rape she has to give up the rapist. Or the abortion provider has to both give up the rapist and a dna sample of the aborted fetus so the rapist can be identified.
What is it that this will resolve? It doesn't resolve the problem of a child whose doctors say she is at risk of dying not being able to get the medical care she needs.
In this case the rapist was identified.
In general, I would ask you who you are to tell a rape victim what she has to do. In many if not most countries an 11-year-old who is pregnant is by definition a rape victim and the child shouldn't be forced to say any more than she is ready to handle.
Again, that is moot in this case. The rapist is known.
If the rapist is known prosecuting him for the murder of the unborn child should be easy. Ariel Castro is charged with the murders of five unborn children. Amanda Berry was forced to have a baby conceived by rape. Should this six year old be executed?
