The mom not only knew her daughter was being abused, she watched — and even participated, according to the documents.

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.

On July 26, as Delta Flight 2809 landed at SFO, deputies coordinated with Homeland Security Investigations to board the plane and make the arrest without alerting the suspect in advance. Viral footage taken by passengers shows law enforcement entering the cockpit and escorting Bhagwagar off the plane in handcuffs.
