A Morrison Christian-school principal who students claimed regularly engaged in vulgar sex talk with his male pupils is now accused of sexually assaulting one of them and attempting to sexually assault a second student.

Charged with sexual assault on a child and unlawful sexual contact in connection with one alleged victim is Daniel Charles Brock, 36, who has been on administrative leave from Silver State Christian School, 14711 W. Morrison Road. Brock also was charged Tuesday with attempted sexual assault on a child involving a second pupil.

Calls to the school inquiring about Brock’s current status at the institution were not returned.

Pam Russell, spokesperson for the Jefferson County district attorney’s office, said investigators “believe Brock was terminated at the end of May.”

In an arrest-warrant affidavit unsealed Tuesday in Jefferson County District Court, male pupils told investigators how Brock repeatedly asked them intimate questions about their sexual activity with their girlfriends. He would ask in graphic terms if they had engaged in specific sex acts with their female friends.

He allegedly asked them if they viewed pornography as well.

Brock also described to the students sex acts he had performed with his wife, according to the affidavit.

When one student complained about Brock’s behavior, the school “suspended the student for unrelated reasons,” according to the affidavit written by David Lynn, an investigator for the Jefferson County DA’s office.

The students also claimed that Brock fondled male students in both school hallways and in Brock’s office.

One student claimed that on a trip to California, when 11 students traveled to what was described as “Brock’s family Christian camp,” Brock engaged in aggressive fondling.

When they stopped in Las Vegas on the way to California, one student said that he was forced to sit in the front of the van with Brock. That night, he said, Brock demanded he sleep in a bed with him. There, he allegedly rubbed the student’s lower back and talked about sex and his wife.

Investigators were told that once in California, all the boys shared a cabin with Brock. One student said that after he was in his bunk, Brock came over and rubbed his legs. He described how on other occasions, as they sat around a campfire and took walks together, Brock would fondle his genitals.

One of the alleged victims said the fondling started when he was in the 10th grade and continued through his senior year.

During the years of abuse, the student told investigators that “all he wanted to do was graduate.”
