The Contra Costa District Attorney's Office charged Rustom Bhagwagar and Jennifer Powell each with more than a dozen felonies, including counts of engaging in a sexual act with a child 10 years old or younger, oral copulation with a child, forcible lewd acts upon a child, and aggravated sexual assault of a child.

Prosecutors say the suspected abuse began when the girl was only six years old and continued until she was 11, around the time Powell and Bhagwagar ended their relationship.
