The mother and rapist boyfriend should be jailed for life and the poor girl should have had access to post-rape emergency care. Morning after or whatever is used to insure rape victims don’t become pregnant.
I don't know under what circumstances the morning-after pill is available in Chile, but in the US it is now available OTC w/o prescription to people of any age. The ""boyfriend"" will probably stock up on them after he gets out of jail, so as to protect his azz in the future, and t'hell with physical, emotional, and spiritual wreckage to the girl.
I'm fairly sure that's not what you want.
