COLUMBUS, Kan. — A Kansas woman has been convicted of killing a man who had warned child welfare officials that she was planning to kidnap her children from foster care and take them out of state.

Crystal Galloway, 37, of Scammon, was found guilty Wednesday of first-degree murder, arson and interference with law enforcement in the May 2015 death of 59-year-old Robin Fought, of Dennis, The Joplin Globe reported ( ). She and her boyfriend, 19-year-old Dakota Cunningham, were arrested two days after the killing in Oklahoma.

During the trial, prosecutors played a voicemail that Fought left for a Kansas Department of Children and Families caseworker in which he warned that Galloway was planning to flee the state with her children. Five of Galloway’s six children were placed in state custody in 2014 and she was only allowed supervised visits.

Days after leaving the message, Fought’s body was discovered lying face down in a field near his burning pickup truck. Evidence technicians testified that Galloway’s DNA was found on the handle of a knife used to stab him. A picture also was found on Galloway’s cellphone of Fought slumped against the door of his truck with blood on his clothes, according to testimony.

On the night of the killing, Galloway and Cunningham showed up at the Welch, Oklahoma, home of an acquaintance and shared that Galloway was pregnant. The acquaintance testified that she gave the pair food and loaned them a tent, but that she was alarmed the next day when they told her that Cunningham had stabbed Fought, and that he had done so in self-defense. She said the couple told her that Fought had pulled a knife when Cunningham tried to get paid for helping to collect junk.

Galloway, who gave birth in December, testified that she had tried to take the knife away from Cunningham. Asked how a photo of the bloodied victim got on her phone, she said that Cunningham had access to the phone.

Cunningham was deemed mentally unfit to stand trial and is being evaluated and treated at a state psychiatric hospital. Meanwhile, one of Galloway’s children has run away from her foster home and remains on the run, according to testimony.
