Sheriff's Deputy Craig Chamberlin says the body was found Friday in the trunk of a car near apartments on Spokane's South Hill area. The woman was reported missing March 7.
Chamberlin says the dead woman's daughter, 29-year-old Racheal Colby, was arrested for investigation of rendering criminal assistance and trafficking in stolen property. Colby's boyfriend, 32-year-old Juan Sifuentez, was arrested for investigation of second-degree murder.
Chamberlin says the investigation continues.
