MANCHESTER, NH - After nearly two full extended days, Kayla Montgomery finished testifying against her estranged husband Adam in his trial for the murder of his daughter Harmony.

Harmony Montgomery was reported missing in late 2021, but hadn't been seen since 2019. Prosecutors are making the case that her father Adam beat the little girl to death on December 7, 2019, due to a bathroom accident, before spending months manipulating and concealing her corpse to avoid getting caught. Adam's wife Kayla, Harmony's stepmother, is the state's key witness.

According to prosecutors, Kayla is a recovering drug addict and domestic abuse victim who lied about Harmony for years to protect Adam as he abused her, and she was too scared to come forward. "Why stay with someone who does what he did to a helpless girl like this?" prosecutor Christopher Knowles asked Kayla on the stand Monday. "Because I still cared about him," Kayla answered through sobs.
