EVANSDALE, Iowa (AP) — Authorities say they believe they’ve found the remains of a missing Arizona woman and her stepfather in Iowa inside the stepfather’s car after it was found buried in an undeveloped lot. The Waterloo Courier reports that authorities were waiting for confirmation from a medical examiner that the remains found on a dead-end road in Evansdale, Iowa, are those of 28-year-old Elissa Landry and 45-year-old David Batten, of Chino Valley, Arizona.

Landry and Batten were reported missing April 19. No arrests have been made, but a 24-year-old suspect who was formerly from Waterloo, Iowa, has been detained.
