Kayla Montgomery cross-examined in trial of estranged husband accused of killing young daughter

MANCHESTER, N.H. — The estranged wife of the New Hampshire man accused of killing his 5-year-old daughter, Harmony Montgomery, returned to the stand on Monday.

Kayla Montgomery, 33, who has a plea deal with the state, began her testimony on Friday.

She offered gruesome testimony as a key star witness in the trial, saying that her husband violently punched the little girl when he flew into a rage on Dec. 7, 2019, shortly before they noticed her lifeless body.

But Adam’s lawyers are attacking Kayla’s credibility because she lied more than once to a grand jury.

Adam Montgomery is charged with second-degree murder. He told the judge he intends to plead guilty to charges of abuse of a corpse and falsifying evidence.
