Card #01: What the parties agree and dispute
Canonical URL: https://lindsay.conspirograph.com/topic/defense-case/card/2
The trial's central legal divide.
[VERIFIED FACT] Defense counsel conceded that Lindsay Clancy physically caused the children's deaths; the defense contests criminal responsibility, not identity. [Defense stipulation report](https://www.courttv.com/news/defense-lindsay-clancy-willing-to-stipulate-to-her-involvement-in-kids-deaths/) · [Trial Day 1](https://www.youtube.com/watch?v=_v9vz_Nw3lE)
[ALLEGATION] The prosecution argues that the errands, communications, timing, and scene show intentional and planned killings by a criminally responsible actor. [Trial Day 1](https://www.youtube.com/watch?v=_v9vz_Nw3lE)
[DISPUTED CLAIM] The defense argues that severe mental illness and medication effects left Clancy legally unable to appreciate wrongfulness or conform her conduct to law. Defense experts had not testified by the Day 11 cutoff.

Canonical URL: https://lindsay.conspirograph.com/topic/defense-case/card/29
The defense's legal claim at trial.

Card #05: Symptoms versus legal conclusion
Canonical URL: https://lindsay.conspirograph.com/topic/defense-case/card/18
Why serious symptoms do not decide the verdict by themselves.
[VERIFIED FACT] The Massachusetts criminal-responsibility test asks whether mental disease or defect removed substantial capacity to appreciate wrongfulness or conform conduct to law; a diagnosis alone does not resolve that test. [Massachusetts model instruction](https://www.mass.gov/info-details/model-jury-instructions-on-homicide-i-criminal-responsibility)
[UNKNOWN] Defense expert testimony addressing that ultimate question had not begun by the Day 11 cutoff. [Court TV tracker](https://www.courttv.com/news/lindsay-clancy-trial-opening-statements-set-for-mom-accused-of-killing-her-3-children/)

Card #07: An evolving regimen
Canonical URL: https://lindsay.conspirograph.com/topic/defense-case/card/20
Why the number of prescriptions can mislead.
[DISPUTED CLAIM] The defense says thirteen medications were prescribed across roughly four months; public testimony describes starts, stops, tapers, dose changes, and discontinued bottles, not thirteen drugs taken simultaneously.

Canonical URL: https://lindsay.conspirograph.com/topic/defense-case/card/44
An affidavit characterization under dispute.
[ALLEGATION] A warrant affidavit used language suggesting investigators were examining whether Clancy may have researched ways to kill. [Warrant packet](https://www.insideedition.com/sites/default/files/inline-files/Linday%20Clancy%20Search%20Warrant.pdf)
