GERING, Neb. (AP) — The mother of a western Nebraska child who was slain in 2008 has been detained as a material witness against a man who’s scheduled to go on trial Monday.

Charyse Geurts is expected to testify next week in the trial of her former boyfriend, 28-year-old Dustin Chauncey. He’s charged in Scotts Bluff County District Court with child abuse resulting in the July 2008 death of 2-year-old Juliette Geurts.

Prosecutors had obtained a Nebraska order to detain Geurts, who was taken into custody in Texas. She arrived Wednesday at the Scotts Bluff County Jail. Prosecutors want to keep Geurts in custody until after her testimony is finished.

Judge Leo Dobrovolny has said he likely would rule Friday on whether the county may continue to hold Charyse Geurts.
