Warning: This article contains discussion of child death and suicide, which some readers may find distressing.
A court has heard that Lindsay Clancy spent the morning building snowmen with her three children before strangling them to death with an exercise band.
Her ex-husband, Patrick, gave his first witness statement this week, backing up the Massachusetts mum's defence that she'd been battling severe postpartum psychosis before the January 2023 attack.
Her team have raised an insanity defence, citing that Lindsay had been prescribed medical treatment for psychiatric issues that developed postpartum following the birth of her youngest son, and that she spent several days at a psychiatric institution in the weeks before the attack.
Lindsay also attempted to take her own life that day, which resulted in her becoming paralysed.
Prosecutors argue, however, that Lindsay, 35, had 'intentionally' killed her daughter Cora, five, and sons Dawson, three, and Callan, eight months.

In court earlier this week, Patrick - who has since divorced Lindsay and remarried - told Plymouth Superior Court Judge William Sullivan and a 12-member jury how his ex had spent the hours leading up to killing her children.
He recalled that Lindsay spent the morning with their daughter at a doctor's appointment before the pair returned home.
With her sons, the family then built a snowman together while Patrick worked downstairs in their basement.
Claiming it was one of Lindsay's 'best days', he recalled: "She seemed happy."
Patrick doesn't dispute that he ventured out to run errands that afternoon - to pick up takeout food and a prescription for Lindsay - while she murdered their three children and attempted suicide.
Patrick claims Lindsay spent the morning of the attack building snowmen with the children (Boston 25 News) The prosecution is using this element of the story against Lindsay, alleging she looked into how long it might take Patrick to return home before acting.
Plymouth County Assistant District Attorney, Shanan Buckingham, claimed in court: "One by one, [Lindsay] grabbed exercise bands around each one of the kids’ necks and pulled until their little bodies were limp and lifeless."
Despite this, Patrick insisted Lindsay had been 'very depressed' before the alleged attack, and that in the immediate month prior, 'her big spiral started'.
"She started to lose a lot of weight, and she became very depressed, and she was having a really hard time," he said, per the BBC. "She was having a really hard time. She started to say that she was suicidal."
Patrick and Lindsay filed a civil lawsuit earlier this year, accusing her medical providers of both failing to issue a proper diagnosis and not monitoring her 'severe postpartum psychiatric condition' after prescribing her treatment.

He also claims he asked Lindsay 'if she needed to be kept away' from the children, even though she 'did not show any intention of harming the kids'.
"It was very confusing," Patrick continued. "The next minute, she was making them lunch or playing with them."

Prosecutors allege the following took place this day:
Morning: Lindsay takes Cora to a scheduled pediatrician appointment. After returning home, they play in the snow with Dawson. She sends photos of the kids to Patrick and her mom.
4:02pm: Lindsay searches for ‘kids Miralax’ (a laxative) on her phone, and 11 minutes later looks up ‘take out 3v’, referring to restaurant ThreeV in Plymouth. She uses Apple Maps to calculate how long it would take to drive from the family’s home to ThreeV.
4:47pm: Lindsay rings a CVS in Kingston to ask if they have any Miralax in stock. A manager tells her they don’t, but they do have similar medications.
The manager later tells authorities that she did not slur her words or sound impaired during the call.
4:35pm: Lindsay texts Patrick, who is working from home: “Any chance you want to do takeout from 3V … I didn’t cook anything … It’s been a long day.”

5:15pm: Lindsay allegedly texts Patrick: “Pedialax liquid stool softener.” He then leaves to pick up the medication.

5:54pm: Patrick gets to ThreeV, pays for the food and leaves.
6:09pm: Patrick returns home. “The first thing he noticed was the silence,” prosecutors say. “He did not see or hear the defendant or the children.”
