Summary:

Heilbrun retained his criminal-responsibility opinion while acknowledging severe illness, adverse medication reactions, possible psychosis indicators, interview limits, and no detected malingering.

Body:

[SWORN TESTIMONY] On cross, Heilbrun acknowledged that Clancy had severe mental illness, reported adverse psychotropic-medication reactions, felt hollow or detached, and described intrusive thoughts she feared others could hear. He said acute psychosis had been one possible explanation and that psychosis can affect memory, but he retained his bipolar-II, no-command-psychosis, criminal-responsibility opinion. [SWORN TESTIMONY] He acknowledged interviewing Clancy more than three years later, roughly $54,000 in billed work, and no publication focused on postpartum psychosis. [SWORN TESTIMONY] On recross, he agreed a test did not indicate that Clancy lied or malingered during their interviews. [SWORN TESTIMONY] Heilbrun said Clancy told him she cut the bedroom screen before jumping, while the screen was not cut; he also said psychosis could affect memory accuracy. These qualifications affect weight and alternative explanations but do not independently prove psychosis, negligent treatment, fabrication, or staging.

Structured claims:
- [sworn_testimony] Heilbrun acknowledged severe mental illness and adverse psychotropic-medication reactions from approximately October 2022 through January 2023, while declining to opine whether providers delivered proper care.

- QUALIFIES: Trial Day 20 noon · Heilbrun concludes criminal responsibility; rebuttal continues — https://lindsay.conspirograph.com/topic/trial-day-developments/card/241. Cross and recross added severe-illness, adverse-reaction, possible-psychosis, interview-limit, and no-malingering evidence that bears on the weight of Heilbrun's retained-capacity opinion without superseding it.

- SUPPORTS: Avram Mack · completed cross, redirect, and interview-video admission — https://lindsay.conspirograph.com/topic/psychiatric-treatment/card/235. Heilbrun's recross concession that testing did not indicate lying or malingering is consistent with the earlier testing evidence Mack acknowledged, while neither validates every reported symptom or memory.

Heilbrun's account of an untrue screen-cutting recollection adds a memory-reliability question to the observed raised-screen evidence but supplies no evidence of staging or another person's involvement.
