The holdout juror in the Lindsay Clancy murder trial has been taken to a “secure location,” his attorney announced Thursday, after other members of the jury in the high-profile case alleged the lone juror had doubts the mother of three was sane when killing her children.

Michael Desronvil was the holdout juror in the Massachusetts trial, which ultimately ended in a mistrial after the jury was unable to make a unanimous decision. Several other members of the jury have since come forward with accusations that Desronvil had admitted to having doubt, but refused to agree to a not guilty by reason of insanity verdict.
