PLYMOUTH, Mass. — Lindsay Clancy’s lawyer stunningly questioned, “Where is the evidence” that the mother of three killed her kids — after spending weeks in court insisting she was psychotic when she fatally strangled them.

Defense lawyer Kevin Reddington asked Judge William Sullivan to find the 36-year-old Duxbury, Massachusetts, mom not guilty on three counts of first-degree murder after a grueling six-week trial that ended with a hung jury earlier this month.

“Where is the evidence that she did this?” Reddington asked the court Tuesday morning.

The 75-year-old veteran attorney claimed the DNA and fingerprint evidence were “woefully deficient,” the prosecution’s timeline was “ridiculous,” and the police investigation was inadequate.

“In this case, there was no investigation. They just immediately assumed that this woman was guilty,” Reddington said.

The impassioned lawyer also claimed there’s “no evidence” Clancy admitted to the killings — instead, she was told by others what they believed happened when she awoke from sedation at the hospital.

“This entire case is based on speculation,” he argued.

“She was told what happened. She had no memory of what happened,” the lawyer added. “There’s no evidence that she admitted that she did this.”

The stance in court Tuesday – the first hearing since the mistrial was declared Sept. 4 – appeared to be in stark contrast to Reddington’s strategy at trial not to contest the killings but to claim Clancy should be found not guilty by reason of insanity.

But Reddington said the fact that Sullivan denied his request to split the trial into two parts — whether she was guilty of murder and if she was criminally responsible — put him in a “conundrum” of having to admit she carried out the crimes in order to put forth the insanity defense.

“We are put in a conundrum where we have to admit culpability in order to raise the issues of criminal responsibility,” Reddington explained.

Afterward, prosecutor Shanan Buckingham claimed Reddington was only now raising questions about whether or not the mom carried out the stranglings.

“What we heard over and over from the counsel during the trial were objections when we presented evidence of the actual crimes where he objected, ‘She admits that she did this’… but now he’s saying there’s not enough evidence,” Buckingham argued.

“The suggestion that there is not enough evidence, I’d argue, is a laughable argument,” she said.

Prosecutors claimed at trial that Clancy coldly planned and executed the slayings of her three young children: Cora, 5, Dawson, 3, and Callan, 8 months.

But Reddington wanted his client to be found not criminally responsible, claiming she was in the throes of severe postpartum psychosis at the time and hallucinated a voice commanding her to 𝘬iᩚll the kids and herself.

Despite Reddington’s latest legal maneuvering appearing at odds with his previous arguments, two Massachusetts lawyers — who are not connected to the case — explained how it may not totally contradict his trial tactics.

“I think he’s pushing the point that, look judge, if you’re going to consider whether or not this case can move forward, go back to the beginning and allow me to make a motion that they haven’t even established probable cause for these charges here,” lawyer Brad Bailey told The Post.

But Bailey and fellow Boston lawyer, Peter Elikann, both acknowledged the chances of the judge granting the motion to find Clancy not guilty are slim at best.

“I think he has an uphill battle here,” Bailey predicted.

Elikann explained it’s not uncommon for a judge to go their whole career without ever once granting this specific type of motion.

Still, “It didn’t strike me as contradictory because I understood that this is a very technical legal argument that the prosecution did not produce the evidence,” he added.

After Reddington made his arguments Tuesday, Buckingham reminded Sullivan about testimony that Lindsay Clancy’s DNA was found on the ends of the exercise bands she used to strangle the kids.

At trial, the jury also heard testimony from Clancy’s then-husband, Patrick Clancy, that she sent him out on errands for roughly an hour and when he returned home, he found his children lying motionless and unresponsive on the basement floor with exercise bands around their necks.

The grieving father told the court how he saw his then-wife lying on the ground in the backyard with wounds to her neck and wrists after she’d attempted to take her life by throwing herself from her second-floor bedroom window.

The jurors learned from testimony that Lindsay Clancy struggled with her mєntal health for four months leading up to the alleged murders — including regularly seeing a psychiatrist, calling a sᩚuᩚiᩚcide hotline on two occasions and checking herself into a mєntal institution for nearly five days.

She was prescribed 13 powerful prescription medications by five different providers during that time — drugs which Reddington claimed worsened her declining mєntal state.

Sullivan said Tuesday he would rule on Reddington’s motion to find Lindsay Clancy not guilty at a later date.

During the hour-long hearing, prosecutors didn’t announce whether they are planning to retry the case –saying they first wanted to hear the judge’s rulings on Lindsay Clancy’s post-trial bids to have the charges tossed altogether.

Reddington also told Sullivan he wouldn’t be available for a potential second trial until June, as both he and prosecutors asked for the judge to hold off on picking a trial date until they return to court on Nov. 2.
