Houston police brought Seaton back early Wednesday morning from Milam County. He surrendered there on Tuesday after a tearful plea by the boy's biological father.
Homicide investigators are questioning Seaton in the death of 4-year-old Dustyn Roff. Police say Seaton attacked the boy after getting into an argument with Roff's mother, Britni Glover.
"I feel like it was my fault. I should have done something. He was my baby," she told Eyewitness News on Tuesday.
Glover, who is Seaton's girlfriend, faces charges of injury to a child by omission for not stopping the alleged abuse.
On Tuesday, we also learned CPS had two previous reports of abuse involving the mother and child but a spokeswoman says when they followed up, they could never find the two.
Seaton, 21, is charged with capital murder.
