FORT WORTH -- A Fort Worth man was in custody Sunday accused of sexually assaulting and beating to death his girlfriend's 2-year-old daughter, whom he had been baby-sitting.
Authorities arrested Donald Ray Sparks, 20, on Saturday, a day after Brelynn Nobles died at 12:52 a.m. at Cook Children's Medical Center in Fort Worth.
The Tarrant County medical examiner's office has ruled her death a homicide caused by "internal hemorrhaging associated with shock." It attributed the internal hemorrhage to "blunt trauma to the abdomen suffered during an assault by another person."
At the time of her injuries, Brelynn's mother was at work, and Sparks was taking care of her, police said. Sparks was interviewed numerous times before he was arrested Saturday.
He was in jail Sunday with bail set at $100,000.
He is expected to be charged with capital murder and aggravated sexual assault of a child, police said.
No charges are expected to be filed against the mother, police said in a news release.
Marissa Gonzales, a spokeswoman for Child Protective Services, said Brelynn had four siblings, three of whom lived in the same home. She said the agency has placed those children -- a 4-year-old twin boy and girl and a 1-year-old girl -- with a relative.
Gonzales said the children are in good health.
According to a Fort Worth police report, officers were sent to a home in the 5900 block of Wilkes Drive about 9:35 p.m. Wednesday.
The CPS spokeswoman said the family had no history with CPS.
