Lindsay Clancy’s lawyer lost his fourth attempt to get the murder charges his accused killer mom client faces thrown out Thursday.

Judge William Sullivan denied a motion by Clancy’s lawyer, Kevin Reddington, to have her found not guilty on all three first-degree murder charges after the high-profile case ended in a mistrial on Sept. 4.

Reddington, 75, argued the motion in court Tuesday, questioning the evidence that the 36-year-old mom strangled her three young kids with exercise bands.

“Where is the evidence that she did this?” he asked the court, before insisting, “This entire case is based on speculation.”

But Sullivan ruled in a decision Thursday that prosecutors had presented sufficient evidence at trial of Clancy’s alleged crimes and therefore he couldn’t drop the charges.

“There was evidence introduced, both physical and circumstantial, that would permit a rational trier of fact to find beyond a reasonable doubt the elements of the charge of murder,” the judge declared.

Here’s the latest on Lindsay Clancy’s murder trial

At the six-week-long trial, prosecutors claimed Clancy coldly planned and executed the murders of her kids, Cora, 5, Dawson, 3, and Callan, 8 months, in their Duxbury, Massachusetts, basement on Jan. 24, 2023.

But Reddington asked the jury to find her not guilty by reason of insanity, claiming she was experiencing extreme postpartum psychosis and heard a voice commanding her to kill the kids and herself.

Reddington previously tried to get his client’s charges dropped three other times — but Sullivan denied every attempt.

The trial ended earlier this month after the jury, made up of nine women and three men, said three times they couldn’t reach a unanimous agreement after seven days of deliberations.

Several of the jurors spoke out publicly after the mistrial was declared and revealed that 11 members of the panel were in favor of finding Clancy not criminally responsible, while a lone holdout wanted to convict her.

Prosecutors haven’t announced how they plan to move forward with the case and a new trial date has yet to be set.

Clancy is due back in court on Nov. 2.

Reddington didn’t immediately return a request for comment Thursday afternoon.
