Christopher Clements is arraigned via video in Pima County Superior Court in Tucson on Sept. 25, 2018. Clements is accused of killing Isabel Celis and Maribel Gonzalez.

A man accused in the killings of two Tucson girls pleaded not guilty during a hearing Monday in Pima County Superior Court.

Christopher Matthew Clements, 36, was extradited to Tucson for theΒ arraignment in the killings of 6-year-old Isabel Celis and 13-year-old Maribel Gonzalez.

Clements was indicted earlier this month in the girls' killings.

He faces 22 chargesΒ in the killing of the girls. Those charges include two counts of first-degree murder, two counts of kidnapping of a minor under 15, and burglary. He’s also facing 14 counts of sexual exploitation of a minor, which are said to be related to child pornography.

Members of both the Celis and Gonzalez families were in the courtroom for Monday's video arraignment.Β

Clements, dressed in an orange jail jumpsuit, showed little emotion during the short hearing and appeared to have a black eye. Last week Clements was in a fightΒ at the Maricopa County jail, where he has been held for several months on unrelated burglary charges.

Clements' next court dateΒ in Pima County is scheduled for Nov. 19.

Isabel went missing from her midtown home in 2012. Her remains were found in a desert area northwest of Tucson in 2017. Court documents made public last week showed Clements led investigators to Isabel's remains in a dealΒ he made with investigators to get unrelated burglary charges dropped.

Maribel went missing in 2014. Her body was found a few days later in the same general area as Isabel’s. The same court documents showed that investigators have linked his DNA to Maribel's body.

Clements is a convicted sex offender and has a long criminal history that started when he was a teenager.
