An investigation, that started as a search for “endangered subjects,” has turned into a homicide investigation in Chino Valley. Investigators are still looking for 45-year-old David Batten and 28-year-old Elissa Landry. Police say 24-year-old Mitchell Mincks was arrested in Waterloo, Iowa on an unrelated warrant and is a person if interest in their disappearance. Chino Valley Police are traveling to Iowa to interview Mincks. The three were last heard from back on April 19th at around 3:45 p.m. Officers took a missing person’s report on Chino Drive last Tuesday at around 6 p.m. at a home. Batten is the home owner, Landry is his stepdaughter and Mincks is her boyfriend. When officers came back to the home last Wednesday, officers discovered evidence indicating foul play. Officials now say evidence collected during the investigation indicate Batten and/or Landry are deceased. Both Batten and Landry have not been located and either has Elissa’s blue 2013 Subaru Forester, bearing an Arizona Women’s Veteran plate WV1236.
