Williams said Sutherland was arrested after police tested a DNA sample taken from him by court order. Police earlier said they were collecting DNA from all male employees at Hacienda HealthCare, a long-term care facility.
The 29-year-old victim has been incapacitated since the age of 3, according to The Associated Press. Thompson said earlier this month that she was "unable to move, she was unable to communicate." However, in a statement released to KNXV-TV on Tuesday, her family's attorney disputed reports that she was in a coma.
"She has significant intellectual disabilities as a result of seizures very early in her childhood," the statement said. "The important thing is that she is a beloved daughter, albeit with significant intellectual disabilities. She has feelings, likes to be read to, enjoys soft music and is capable of responding to people she is familiar with, especially family.”
Employees at Hacienda said they had no idea she was pregnant before she gave birth on Dec. 29.
Thompson said Tuesday that the baby was in good condition, despite the circumstances surrounding his birth.
“I would just say that we can’t always choose how we came into this life, but we can choose as a community to love this child,” Thompson said.
