Chandler police have arrested Rachel Katherine Brock, 21, as part of an ongoing sex abuse investigation involving her mother, Susan Brock.
Police say that between February 2007 and August 2008, Rachel Brock committed "numerous acts of sexual conduct with a minor and at least one count of furnishing harmful items to a minor," according to a news release. At the time the crimes occurred, the victim was younger than 15, classifying them as dangerous crimes against children, according to the news release. Rachel Brock has been booked into the Maricopa County jail in Phoenix.
The victim is the same child allegedly victimized by Susan Brock, according to police.
Susan Brock pleaded not guilty to charges that include sexual conduct with a minor, sexual exploitation of a minor and furnishing harmful items to a minor.
On Wednesday, Chandler police arrested an acquaintance of Susan Brock, Christian Hart Weems, 37, who faces charges related to computer tampering or altering of data, hindering prosecution and tampering with physical evidence in the Susan Brock case.
Susan Brock is the estranged wife of Maricopa County Supervisor Fulton Brock. Shortly after her arrest, Fulton Brock filed for divorce.
In a prepared statement Thursday, Fulton Brock said: "Shocked and devastated are not words sufficient to describe the news this day or what has transpired over the past two months. In October, my wife of 28 years was arrested and charged with having an inappropriate relationship with a minor. Now, my daughter has been arrested, pending charges."
Fulton Brock said his daughter is being accused of having a relationship with the same young man when she was 18.
"I have filed to divorce my wife. I cannot divorce my daughter. She is my blood. I will always be her Dad. And she needs one now more than ever," he said. "All families are challenged. But no family should ever be challenged this way whether it be ours, or that of the victim and his family."
He added that "justice demands answers and cooperation."
"Nothing can ever make this situation right other than raising awareness so other families can avoid such sorrow," Fulton Brock said. "As a person of faith I ask for your continued prayers."
