A man convicted last month in the first of two murder cases in Tucson is seeking a new trial, according to authorities.
Christopher Clements was convicted Sept. 30 of first-degree murder and kidnapping in the death of 13-year-old Maribel Gonzalez.
He was scheduled to be sentenced Wednesday in Pima County Superior Court, but the date has been moved to Nov. 14.
Court officials also said Clementsβ attorneys have filed a motion for a new trial and a motion for judgment of acquittal not withstanding the verdict.
A Nov. 7 hearing is set for both motions.
A judge also will hear testimony Nov. 14 for a possible change of venue for Clementsβ other murder trial, scheduled for Feb. 2 involving the death of 6-year-old Isabel Celis.
Clements, a 40-year-old convicted sex offender with a long criminal record, is facing life in prison when he is sentenced in the Gonzalez case.
Clements was arrested in 2018 and indicted on 22 felony counts including two counts each of first-degree murder and kidnapping in the girlsβ deaths.
Celis vanished from her parentsβ home in April 2012 while Gonzalez disappeared while walking to a friendβs house in June 2014.
Authorities said Gonzalezβs body was found days after her disappearance while Celisβ remains werenβt recovered until 2017 after Clements led federal agents to the location.
Clements currently is serving a prison term of up to 35 years for a Maricopa County burglary in 2017.

Clements is facing 22 charges that include two counts of first-degree murder, two counts of kidnapping of a minor under age 15, burglary, and 14 counts of sexual exploitation of a minor, which is said to be related to child pornography.Β
He is currently being held in the Maricopa County jail on unrelated charges.
Records show that Clements has a long criminal historyΒ and that he was out of jail on bail when Maribel was killed.
September 21, 2018
UpdatedOn Sept. 21, 2018, the Star obtained new court documents showing that Clements led investigators to Isabel's remainsΒ after asking for unrelated burglary charges to be dropped.
He also asked that his impounded car be released. Investigators agreed to his terms.Β
The same court documents show that DNA taken from Maribel's body was linked to Clements.Β
They also say that investigators found a letter from Clements thatΒ implied there were four bodies left in the desert area.

February 11, 2019
UpdatedOn Friday, Feb. 8, the county attorney's office filed notice that they would be pursuing the death penalty.Β
On Monday, Feb. 11, Judge Deborah Bernini said she would be drafting up a document to address pre-screenings, which includes an IQ screen.
"We don't take five years to try death penalty cases here like they typically do in Phoenix," Bernini told Clements' lawyers, Eric Kessler and Joseph DiRoberto, adding that she wanted to give them adequate time to file an objection to the pre-screening.
The hearing addressed several other items, including the state's motion to appoint a special master to review recordings of dozens of recorded jail phone calls between Clements and Tucson attorney John Kaufmann, who represented Clements in a 2012 case.
