The woman, Deanna Robinson, was 38 weeks pregnant at the time, and home security camera captured a Hunt County Sheriff's Deputy appearing to punch her several times after she was handcuffed.
According to court documents, CPS has a history with the family at their Quinlan home dating back to last September.
Records show "…CPS began investigating after Robinson's 6-year-old stepson told someone that she and the child's father, Jose Llenas, were disciplining Llenas' 8-year-old son with cerebral palsy by putting a sock in his mouth to stop his yelling and would leave him in soiled diapers."
Then, last October, a violent argument happened between Robinson and her husband. The documents say Robinson busted a window.
Documents say that a few days later, the "6-year-old twins have injuries to their legs and appear to be losing weight."
The CPS worker says he puts a safety plan in place for the family.
Robinson addressed questions Monday about CPS involvement with her kids.
"Do you have any prior history with CPS?" FOX 4 asked her Monday.
"Prior to this incident and with our family, we were in the FBSS program. We were receiving services from them," said Robinson.
That program helps families implement CPS recommendations.
But it was last month when things really heated up. On March 1, a fight erupted between Robinson and her husband after he allegedly hit his 6-year-old son in the head, and then Robinson.
"My husband shoved me, which was in the presence of the children," said Robinson. "I shoved him back and picked up Landry at that time and attempted to leave the room, and so the investigation revealed that a domestic violence incident occurred while I was holding an 18-month-old."
The next day, Robinson moved out to her parents' Quinlan home, taking the 1-year-old and leaving her three stepchildren with their father.
