What do you think happened to Lindsay Clancy?

I think that Lindsay Clancy probably suffered a psychotic episode or a series of them that were not diagnosed or treated properly. Contrary to what it says in the press, with the exception of a very small dose of Seroquel (which is usually given at that strength just for sleeping), none of the other medications she was taking were antipsychotics. Seroquel, given at the prescribed strength, was unlikely to have any antipsychotic activity.

I also think, given her alleged symptom presentation to the practitioners who saw her prior to her murdering her children, the medications she was given were reasonable, but they did not seem to work. I strongly suspect that she was probably having some hallucinations and delusions prior to murdering her children that she never reported to those practitioners. In the hospital, after she had murdered her children, she complained of visual hallucinations.

All that said, at least one practitioner was supposedly an expert in postpartum illness despite her apparent lack of experience. I think we could reasonably expect her to be more suspicious than she apparently was about Lindsay's stability going forward, regardless of what Lindsay told her. She could have provided her with psychotherapy, though I understand she was not trained in it - but I'm certain she had and continues to have colleagues who are trained and qualified in it, and one referral

A referral might have made all the difference. Lindsay had three children and a household to take care of; it's a very heavy burden in and of itself for a stable person. Her degree of distress was a red light. A much more comprehensive referral, or set of referrals, was needed, especially since the medications never seemed to work. If the provider felt she was out of her depth, then she should have gotten a consultation, and apparently did not. Dunning-Kruger applies even to professionals.
