Summary:

Heilbrun offered a nonpsychotic suicidal-filicide explanation before an excluded religion reference prompted a denied mistrial motion, a curative instruction, and early dismissal.

Body:

[SWORN TESTIMONY] Prosecution rebuttal psychologist Kirk Heilbrun diagnosed bipolar II disorder but rejected acute psychosis and command hallucinations as the explanation for the killings. He instead described a suicidal or altruistic-filicide theory. [VERIFIED FACT] A religion reference prompted an objection, a defense mistrial motion, and argument outside the jury's presence. Judge William Sullivan denied the mistrial, struck the religion testimony, instructed jurors to disregard it, and dismissed them early. [VERIFIED FACT] Heilbrun did not complete testimony; the judge said he understood the Commonwealth expected one additional witness after Heilbrun. Testimony resumes Tuesday, with closings expected Wednesday. [UNKNOWN] No verdict occurred, and no new scene or third-party evidence changed the staging assessment.

Structured claims:
- [sworn_testimony] Heilbrun testified that he diagnosed Clancy with bipolar II disorder but did not believe she experienced acute psychosis with command hallucinations during the killings.

- [sworn_testimony] Heilbrun opined that Clancy made a serious suicide attempt and killed the children because she did not want to leave them to suffer without her, rather than because a command hallucination controlled her.

- [sworn_testimony] Heilbrun testified that a never-before and never-since voice limited to the approximately 18-minute killing period would be a very unusual hallucination pattern and cited differences in reported wording as relevant to reliability.
