Ah-ha!!! Now it makes sense!!!
So, today, Jan 4th I rape my victim. On Jan 18th she misses her period. On Jan 20th, just to be sure, she calls me, tells me she is pregnant, and I phone up the abortion clinic, which organizes an abortion. This is to be done within the 24th week, which happens at the beginning of June.
But even though I have plenty of time, I do not want to waste any, so I organize something in between, say mid March. I go to my victim's place, kidnap her, bring her to the abortion clinic, have the abortion performed within the 12th week.
No big deal. I release my victim, conscious of the fact that she will never report me to the police. The abortion clinic then freezes the fetus till its due delivery, which happens around end of September, and on October 1st they send my new little boy to my home, ready for my dark satanic purposes.
NOW it makes sense. Thank you for clarifying it.
