BELLEVUE, Neb. (AP) – A police captain says authorities are searching the Missouri River south of an Omaha suburb because a man told officers he dumped his wife’s body there.

Sarpy County prosecutors have charged 37-year-old Brandon Norton with second-degree murder, and he’s being held without bail. Court records don’t list the name of an attorney who could comment for him.

Police say he told Bellevue officers what he’d done after surrendering Tuesday evening, but authorities have been unable to find 32-year-old Jennifer Norton or her body.

Police Capt. Tim Melvin said Thursday that investigators think Norton killed his wife Monday evening and then hauled her body to the river south of Bellevue. Melvin says Brandon Norton has told investigators how he killed his wife, but Melvin wouldn’t share the information.
