PHOENIX — The daughter of a county supervisor has been arrested on suspicion of sexual misconduct with the same teenage boy that her mother is accused of sexually abusing over a three-year period, police said Thursday.
Rachel Katherine Brock, 21, was arrested Wednesday on three counts of sexual conduct with a minor and one count of transmitting obscene material as part of an ongoing investigation surrounding her mother, 48-year-old Susan Brock.
Both women were being held without bond at the Maricopa County jail.
In Rachel Brock's initial court appearance, acting attorney John Rock argued that the judge should free her on bond because there appeared to be no physical evidence to support any of the charges. Rock also said the teen would have been asked if he had been a victim of any other sexual abuse when Susan Brock was arrested in October.
"It appears that he's given contradictory information," Rock said. But the judge wasn't persuaded.
It was unclear whether Rachel Brock had a permanent attorney. Susan Brock's attorney, Pheron Hall III, did not immediately return a call seeking comment Thursday.
Rachel Brock is the daughter of Maricopa County Supervisor Fulton Brock, and Susan Brock is his wife of 28 years. The family lived together in the Phoenix suburb of Chandler but Fulton Brock filed for divorce after his wife's arrest.
Rachel Brock is accused of committing numerous sex acts with the teenage boy between February 2007 and August 2008, and sending him nude photos and a video of herself masturbating; none of the acts involved intercourse. The boy was 14 at the time, and Rachel Brock was 18, classifying the crimes as dangerous crimes against children.
Police said that between August 2007 and October of this year, the teen met Susan Brock for sexual trysts. Susan Brock reportedly provided the boy with cell phones, and police seized text messages reportedly recording sexual exchanges between the two.
Chandler police Sgt. Joe Favazzo said it appears that Susan and Rachel Brock didn't know about each other's relationship with the teen.
"You have a situation where you have a mother who's abusing a juvenile victim, seemingly unknowingly to the daughter, or vice versa, and the daughter is also abusing the same victim," Favazzo said. "I just can't imagine a mother and daughter having this conversation, and the investigators say they don't have anything indicating the two of them knew about it."
The boy, now 17, told police that Rachel Brock began abusing him in 2007 by inappropriately touching him during a trip to California, and it escalated to other sexual contact in a vehicle about a month later, according to a court document released Thursday. The boy also told police there was sexual contact with Rachel Brock at the Brocks' home and at a property owned by the Brock family.
Susan Brock was arrested in October on two counts of child molestation and two counts of sexual contact with a minor involving the same boy.
The teen told police Susan Brock would pick him up at school or home and drive him to secluded areas where they would have sexual contact in her car, although there was no intercourse, according to a court document. Authorities say Susan Brock also helped the boy meet his girlfriend and provide places where the young couple could have sex.
In a statement Thursday, Fulton Brock said "'shocked and devastated' are not sufficient words to describe the news this day or what has transpired over the last two months."
"I have filed to divorce my wife. I cannot divorce my daughter," Fulton Brock said. "She is my blood. I will always be her dad. And she needs me now more than ever."
A third woman, Christian Hart Weems, 37, was arrested in the case Tuesday on suspicion of obstructing a criminal investigation and conspiracy to commit computer tampering. She's accused of deleting potentially incriminating e-mails between the boy and Susan Brock. Police say Weems is a friend of Susan Brock.
