Tucson police released a report related to the recovery of the remains of Isabel Celis.
According to the heavily redacted documents, officers were apparently led to evidence by a man who was worried "his family was going to be in jeopardy."
Police also interviewed a man who claimed not to be involved in the crime.
"He denied involvement in the kidnapping and murder of (redacted)," the report says. "He said that had he had been involved in something like that he would be dead and it would be from his own hand. Stated that when he went into a house there was no one home. He said that we could look into his history."
It's not clear whether the two men were the same.
Isabel Celis, who was 6-years old at the time of her disappearance, went missing from her family's home near Broadway and Craycroft in April 2012.
The incident date in the report was listed as March 3. A warrant was served March 24 and the report was filed April 24. Police announced
that they had found Isabel's remains in a remote area of Pima County March 31.
Judge Jane L. Eikleberry has ordered the TPD warrant sealed for 180 days, which would make it available in September.
The report also says that police recovered SD cards at the scene, and that remains were confirmed to be those of Isabel Celis by the Pima Medical Examiner following the analysis of DNA samples by Bode Forensics in Lorton, Va.
