BELLEVUE, Neb. (AP) — Police in an Omaha suburb say they’ve been unable to find a woman whose husband says he killed her.

Bellevue police Capt. Tom Dargy says the 37-year-old man told officers what he’d done after surrendering Tuesday evening. Investigators obtained warrants to search the man’s home, but they didn’t find the woman or her body.

The man was arrested on suspicion of second-degree murder. Court records don’t show that he’s been formally charged.
