Remember that by the time of the last baby, this woman was G10, P10.
As in, gravida 10. Ten pregnancies and deliveries that we know of. That is pretty uncommon in the U.S. nowadays. Some religious and cultural groups have a lot of kids, but 10 in a woman of her age is a lot.
Labor and pushing may have been extremely fast by about baby #4. We don't know if they were all full term.
And she may not have kept accurate dates, or any kind of dates, of when the babies were born. Actually, keeping the bodies in the garage of the home she and her 3 girls lived in is very odd and "disorganized behavior" even for a serial killer. You would think she might want to dispose of the bodies over time to cover her actions. Surely she knew they were still in the garage in boxes, and could be discovered by anyone.
Just a horrific case. I hate to admit this, but with so many bodies, I actually wondered if any of the babies were birthed by her daughters. DNA will be interesting.
I am not asking whether she kept accurate dates. I am asking whether she gave the police accurate years. She claims all these babies were born before hubby was send to prison.
It would have made more sense to me if they were born after hubby went to prison.
