ST. PAUL, Minn. (AP) — A missing Minnesota woman’s husband was charged Thursday with murder, after investigators found blood on the floor, furniture, walls and stairs of the couple’s home as well as evidence of an extensive effort to cover it up.

Authorities said they have not found 30-year-old Kira Trevino’s body, but they believe she’s dead because of the amount of blood found in her car and in the couple’s St. Paul home, and because it wasn’t like her to disappear without telling anyone.
