A couple is facing charges of child abuse related to incidents at a home with at least 21 children. The investigation began after an allegation of child abuse was received. A nanny was recorded allegedly shaking and hitting an infant, who lost consciousness and was later hospitalized.

The nanny, who was seen on video, has not been taken into custody and is believed to have fled to China. The couple, Silvia Zhang and Guojun Xuan, were initially arrested but not charged at the time to allow the investigation to continue.

Further details on the case are available from the source, including the events that led to the charges and the current status of the investigation.
