Lindsay Clancy was practically “a vegetable” before she allegedly killed her three young kids, her lawyer claimed at a hearing Thursday — as the mom appeared grim-faced in court.

Clancy, 35, looked forlorn, her eyes downcast, as she was brought by wheelchair into a Plymouth County courtroom in Massachusetts, Thursday for a hearing ahead of her trial set for next month.

Her lawyer, Kevin Reddington, described for a judge the harrowing months during which Clancy battled postpartum depression and her husband, Patrick Clancy, was shuttling her around for  doctor appointments and hospital stays.

“I’m talking about when Patrick would take his wife in the condition she was in, as a vegetable practically, and see these doctors and they would prescribe her medication,” Reddington said.

For the four months leading up to the murders, Clancy’s mom, dad and sister helped to take care of Lindsay and Patrick’s kids so they could deal with Lindsay’s mental health problems, Reddington explained.

“It’s her mother and father and her sister who lived this torture along with Pat … lived with her and her family to try to help out,” Reddington said.

The defense attorney said they could testify at trial about, “What they observed, what they did to try to help during that period of time that Lindsay and Patrick were consulting with doctors. When she went to McLean Hospital and they were taking care of the kids and helping out.”

Clancy is accused of strangling her kids Cora, 5, Dawson, 3, and 8-month-old Callan with elastic workout bands at her Duxbury home on Jan. 24, 2023. Clancy then slit her wrists and throat and jumped out of the second story of her home, prosecutors have said.

She was partially paralyzed and is now wheelchair-bound.

Redding is expected to ask a jury to find her not guilty by reason of insanity, claiming she was suffering from severe postpartum psychosis at the time of the crimes.

Lindsay was in court for the second-to-last hearing where prosecutors and Reddington were arguing over what evidence should and shouldn’t be allowed to come in at trial.

Judge William Sullivan sided with Reddington that Lindsay’s mother, father and sister didn’t need to be barred from listening to other witness testimony at trial.

The judge said he would likely allow a jury to hear Patrick’s heartbreaking 911 call when he arrived home to find Lindsay lying wounded in their backyard before discovering all three of their kids dead in the basement with elastic bands around their necks.

And Sullivan also approved the prosecution motion to allow the jury to be taken to view the house where the murders occurred — despite the fact the home is currently owned by someone else.

Lindsay and Patrick have filed lawsuits against the doctors treating her, claiming she was misdiagnosed and overmedicated.
