BOSTON — A lawyer for the lone holdout juror in the Lindsay Clancy trial is calling a motion to look into his client’s background, “disgusting,” saying it’s an attack on the U.S. Constitution.

“The Looney Tunes motion filed ... by Kevin ‘Shooter McGavin’ Reddington to investigate Michael (Peguy Desronvil) is not just an attack on Michael for being the courageous lone holdout juror,” Edward Andrew Paltzik said in a post on X Tuesday. “If the new normal is that jurors are going to face brutal reprisals for disagreeing with a defense attorney, you can kiss the Sixth Amendment goodbye.”

The Sixth Amendment guarantees the right to a speedy and public trial, as well as an impartial jury.

Paltzik warned in his post that the tables could turn, writing that if there was a hung jury split 11-1, guilty to not guilty, “I doubt you folks would be alright if the District Attorney then filed a motion to investigate that lone holdout standing in the way of a conviction.”

Fellow jurors in the Clancy case reported to Judge William Sullivan that one juror had expressed doubt but refused to find Clancy not guilty by reason of insanity like the other 11 panelists. Desronvil has refuted that characterization, saying he didn’t have doubt.

On Sept. 4, Sullivan declared a mistrial in the case after nearly 40 hours of deliberations. The Plymouth County district attorney’s office has not announced if it will prosecute Clancy again.

The Duxbury mom currently faces three charges of first-degree murder for the 2023 strangling deaths of her children, Cora, 5, Dawson, 3, and Callan, eight months. Clancy doesn’t dispute that she killed the kids, instead Reddington argued that she was suffering from postpartum psychosis at the time and can’t be held criminally responsible.

Since the mistrial was declared, Reddington has filed motions for a required finding of not guilty and to dismiss the case altogether.

On Friday, Reddington also filed a motion for an inquiry into “Juror Doe,” using a pseudonym for Desronvil as the jury list remains indefinitely impounded.

Clancy’s attorney requested information from the Commonwealth on Desronvil’s “record from the statewide domestic violence registry ... including the order now in force and its docket,” any present or prior case information involving the juror from the Plymouth DA, and information from jury background checks the prosecution may have performed.

Additionally, Reddington asked for data from Desronvil’s phone during the deliberations and court logs jurors used to sign their phones in and out.

Desronvil’s attorney, who has also represented President Donald Trump in the past, said that the issue isn’t partisan and anyone who cares about the Constitution should be upset about the inquiry request.

“Kevin Reddington’s disgusting motion to investigate Michael is worthy of nothing but universal condemnation,” Paltzik wrote. “This is certainly not the final word from us on this subject, but merely our first words. It’s all going to backfire spectacularly on sore loser Reddington.”

Reddington declined to comment on the post, via a spokesperson.

Clancy and Reddington will be back in court Sept. 29 for their first hearing since the mistrial was declared.
