Christopher Clements was arrested for unrelated charges and he’s now facing charges for homicide of Isabel Celis And Maribel Gonzales.

Celis, 6, disappeared on April 20, 2012 after she went to bed at her family’s home near Broadway Boulevard and Craycroft Road. She was reported missing by her father, Sergio Celis, the next morning.

Her remains were found in March 2017.

Gonzales, who was 13 at the time of her disappearance, went missing in 2014.

Both bodies were found with close proximity of each other.

The suspect had been in Maricopa County Jail for unrelated charges.

According to the indictment, Clements was charged with two counts of first-degree murder, two counts kidnapping a minor under 15, two counts of second-degree burglary, one count of theft by controlling stolen property, one count of trafficking in stolen property and 14 counts of sexual exploitation of a minor.

In 1998, Clements was convicted of a sex offense in Oregon at the age of 15. He was sentenced to a year and a half in prison plus 10 years of post-prison supervision. He was also required to register as a sex offender.

Officials say Clements was found guilty of failing to register as a sex offender in the state of Florida. That same year, the 36-year-old was charged with violating a protective order against stalking and telephonic harassment in Oregon.

Clements was then charged for providing false information to law enforcement in 2007. In this case, Clements reportedly gave a false name and date of birth to a Tucson Police Department officer two times. The TPD officer was serving a search warrant in another case. The officer said Clements acted suspiciously, by doing actions such as removing an item out of a trash can near a bus stop.
