Clements’ girlfriend told FBI agents Clements knew where to find Celis, according to the court records.
Clements told them he did not kidnap or kill the girl, but he would not tell them how he knew where to find her. He said he would cooperate if authorities released his vehicle and dismissed two burglary charges, according to the records.
He led them to the desert near Avra Valley and Trico Roads on March 3, 2017. While looking for Celis, they walked by the area where deputies found 13-year-old Maribel Gonzales in June 2014, according to the documents.
The records also indicate Pima County Sheriff’s Department detectives have linked Clements’ DNA to Gonzales.
In a letter to his girlfriend, detectives believe Clements referenced a total of four bodies in the desert, but they do not know who the other two victims may be, according to the document.
Detectives found a child’s purple hooded sweatshirt and child’s homework with the name “Mercedez,” according to the document. Mercedes was Celis’ middle name. Purple was her favorite color.
With another warrant, detectives found sexually explicit images of children between the ages of 3 and 13, according to the document.
Detectives also found internet searches for “Isabel Celis,” “body found in desert,” “Arizona cold cases,” “trace evidence found on body,” and “Kauilani Tadeo,” according to the document. Tadeo was a 6-year-old girl who was kidnapped, sexually assaulted and murdered in Hawaii in 2001.
A handwritten note led detectives to interview Clements’ former cellmate. The cellmate said Clements talked about knowing where Celis was. He said Clements was concerned about evidence in his car. He said Clements showed him photos of the Celis house and said that she was taken through the bedroom window, according to the document.
