Lindsay Clancy’s trial over the murder of her three children has collapsed after the jury was unable to come to a decision.

Judge William Sullivan read the jury note aloud: ‘It is with a heavy heart that we cannot come to a decision and will not be able to.’

Shortly after reading the jury’s note, Judge Sullivan declared a mistrial, to the dismay of those in the courtroom.

Clancy appeared ‘crestfallen’ after the announcement, reporters in the room observed.

Clancy’s lawyer is set to appeal the mistrial to the Supreme Court of Massachusetts – with a deadline of an hour, Judge Sullivan said.
