Hundreds of police documents in the Isabel Celis case have just been released, giving us a new look inside the investigation. Isabel Celis disappeared from her Tucson, Arizona, home overnight April 20. She was 6 years old at the time.
Isabel’s dad, Sergio, says the family came home late on the April 20 and he fell asleep on the couch after putting Isabel to sleep in her bedroom. Isabel’s mom left for work at 7 a.m., but did not check on Isabel. Later that morning, Sergio discovered that Isabel was missing and called 911.
