Is that something we can credit to postpartum depression?
Yes, but postpartum depression is different from postpartum psychosis. With postpartum depression, women do not kill their children unless they're having depression with a psychotic episode. (Comment on this story.)
By definition, women are at risk for a postpartum disorder up to the first 12 months after childbirth. However, because many of these conditions go under- or untreated, they can be vulnerable for years. I'm not saying that I can tell that she [Duley] had postpartum psychosis because she had a one- and two-year-old, but I would say that she was clearly in a confused and desperate state of mind.
In Duley's case, it seems like she had gone to pretty great lengths to cover up what she had allegedly done. How do you determine whether or not psychosis is a factor in a case like this?
I think when the mother attempts a cover-up, people tend to believe that psychosis is not a part of it, but again, what we see is that women [suffering from postpartum psychosis] go in and out of psychotic thinking. When they come to, they're really horrified.
Some women, like Duley, who are charged with killing their children do not have prior criminal records. What is the right thing to do with them? Do we send them to jail?
The first thing to do is evaluate the women within a short time after the incident occurred by a licensed mental health practitioner who is trained to do assessments of people. You must make a determination of their mental health status. Then, I think based on that assessment, the woman needs to get treatment for any existing mental health problems. Once she is recovered, she is to be held accountable for what has happened. If it's determined that she was in her right mind, that she was in possession of her mental faculties, that this was premeditated, then you need to take that information into account.
I think in too many of these cases, women aren't evaluated at all or [investigators] wait for weeks or months, so the women have started on medicine. Of course, they're thinking clearly by then. You have to make a medical assessment at or near after the incident occurs so you can determine to what degree she's going to be held accountable.
