An autopsy was scheduled Tuesday for a woman found bound and stabbed to death in her Lodi home.
Officers were called Saturday to the home of Dorothy Wiederrich, 74, in the 2300 block of Woodlake Circle after a relative discovered her body.
Officers did not find any evidence of forced entry into the house, and the motive for her killing is not known.
Detectives have interviewed neighbors and family members to find her killer. Wiederrich lived alone.
