There’s an article in The Washington Post today about the murder of pregnant women. It’s a surprisingly common event, and it probably always has been. Most of the murders are by (ex-)husbands/boyfriends of the pregnant woman, although some are by the wife or another girlfriend of the (ex-)husband/boyfriend, plus there are a few cases like this one where someone steals the baby. It’s estimated that 20% to 40% of American women who die during pregnancy are murdered. A hundred or so years ago, it was approximately 100 times as common to die during pregnancy because of the various medical problems that pregnancy causes. Now that the medical side-effects of pregnancy have nearly all been taken care of, it’s possible to see how often pregnant woman are murdered. There are also a fair amount of women who are killed not too long after having a baby, and the problem of pregnant women being killed by husbands/boyfriends is, in a sense, a subcategory of the problem of pregnant women being beaten by husbands/boyfriends.
I’m not sure why you find a pregnant woman being murdered by someone who steals her baby so much more terrible than a pregnant woman being murdered by a boyfriend/husband (or by another woman that the boyfriend/husband is involved with) In all these cases, it’s somebody killing somebody else because they are an inconvenience. The husband/boyfriend is getting rid of someone who is going to cramp his lifestyle. The other woman is getting rid of competition. The baby-stealer is getting rid of someone else who wants the baby.
