TUCSON, Ariz. (KOLD News 13) – The first murder trial of accused Tucson child killer 40-year-old Christopher Clements continued Thursday, Sept. 15, with more testimony from his former girlfriend.
Clements is facing several charges for allegedly kidnapping and killing 6-year-old Isabel Celis in 2012 and 13-year-old Maribel Gonzalez in 2014. The current trial is for Maribel’s death. Clements will face a jury for Isabel’s death next year.
The trial started last week with jury selections but kicked into high gear Tuesday and Wednesday with opening statements and witness testimony.
Melissa Stark, Clements’ former girlfriend, returned to the stand Thursday.
Stark said she and Clements were living together in the 5800 block of East Elida Street in 2014. That is about two miles from where Maribel went missing, the Broadway and Wilmot area.
On Wednesday, Stark testified she had a “huge argument” with Clements the night Maribel went missing. She said she accused him of being interested in one of her friends.
She said after the argument, Clements left and came back asking for bleach. He then allegedly left again in her vehicle before coming back with more bleach. She said he left yet again in his vehicle and stayed out all night.
When he did return, she said he took a shower, and asked her to clean despite recently giving birth.
On Thursday, she was cross-examined by the defense.
