According to a police affidavit obtained by ABC affiliate KLTV in Tyler, Texas, the woman was allegedly tortured and made to call her captors "master."
Six people were arrested late Tuesday and charged with the aggravated kidnapping of a woman who was held against her will and tortured, according to Sheriff Botie Hillhouse.
"The mother said she awoke Tuesday morning to play video games," Hillhouse said. "She then checked on the three children and found the 18-month-old dead."
