The Texas mother, accused of killing her ill 6-year-old son, was flown back to the US after a joint FBI-India-Interpol operation

Cindy Rodriguez-Singh, the North Texas mother accused of killing her young son, is now in Tarrant County custody, FBI officials announced Thursday.

Days later, Rodriguez-Singh allegedly left for India with her husband Arshdeep Singh, and six other children, whose ages ranged from 5 months to 11 years, the FBI previously said. (Singh is not Noel's father.) Noel was not on the flight, per investigators.
