West Valley Superior Court Judge Richard V. Peel made his decision Wednesday following testimony of a San Bernardino County sheriff's detective who investigated the girls' reports.
Abiathor Stephen Mejico of Rancho Cucamonga is charged with four felony counts of sexual penetration with a foreign object of a victim under 18, five felony counts of unlawful sexual intercourse with a minor more than three years younger, one count of oral copulation with a person under 18, and three misdemeanor counts of sexual battery, according to court records.
Prosecutors say the sexual contact happened when the girls lived with Mejico for a time.
One of the girls, known in court as Jane Doe 1, claimed Mejico forced her to have sex with him - among other things - San Bernardino County Sheriff's Detective Lynn Silvey testified during the preliminary hearing. The girl said the contact happened between August and September 2011, when she was 17 years old.
The other girl, identified as Jane Doe 2, started playing softball for Mejico when she was 12 years old and continued until she was 18, Silvery said.
From late 2010 to the summer of 2011, when she was 16 years old, Mejico committed sex acts with her, Silvey testified based on the girls reports.
When asked why Jane Doe 2 continued to live with Mejico while those things were going on, Silvey answered, "She looked at him as a father figure. He had done a lot of things for her family. She felt she had an obligation to stay there."
Jane Doe 2 told Silvey there were three to four incidents when she would fall asleep and wake up to find the defendant kneeling on the floor next to her, touching her.
"There was one incident where she pushed his hand away but he came back. Another time when she closed her legs he was able to open her legs back up," Silvey testified.
Both girls lived with Mejico so they could go to a better high school and have better softball opportunities, Silvey testified. But the incidents did not overlap.
San Bernardino County sheriff's deputies learned of the case when they responded to a disturbance call on Sept. 30, 2011, at a home in the 6200 block of Taylor Canyon in Rancho Cucamonga.
While there, deputies learned about the accusations.
Mejico, who denies the charges, was arrested that October and released from custody after he posted bail.
He was present and out of custody for Wednesday's preliminary hearing and is scheduled to be back in court in February.
In addition to being a travel ball coach in Rancho Cucamonga for several years, Mejico was also a teacher's aide at Pomona High School, according to authorities.
