Allen and Ina Rogers, the father and mother of the children, were arrested earlier in May. Ten children, ages 4 months to 12 years, were found living in squalor in a Fairfield home.

Prosecutors had already charged Allen and Rogers with child abuse. Authorities also said some of the children were allegedly tortured by their father.
