Police charged three people, including the girl's mother and grandmother.
Around 1:20 a.m. Sunday, police were dispatched to a home in the 2200 block of Webster Avenue for the report of an unconscious infant.
When officers arrived, they found two-month-old girl unconscious.
They immediately rushed her to Shannon Medical Center while another office gave her CPR on the way.
According to court documents, the infant’s 21-year-old mother, Destiney Harbour, gave birth at the home on Aug. 23.
Her mother, 37-year-old Christin Chanelle Bradley, and Bradley's boyfriend, 34-year-old Dustin Wayne Smock, helped deliver the baby.
Bradley told police she cut the umbilical cord and tied it with a shoelace.
But the baby never left the home, including for medical care.
Smock claims he and Bradley laid the baby down to go to sleep Sunday and went to brush their teeth.
When they came back, Bradley claims the baby was not breathing. So, they called 911.
According to court documents, a doctor at Shannon Medical Center found injection sites on the infant’s hand, arm and head.
Her urine tested positive for heroin.
She was also blue.
The doctor said the child was in cardiorespiratory failure when she was brought to the hospital.
According to court documents, he said Smock and Bradley should have noticed the child's medical condition and gotten help much sooner.
He said the girl would have died had she not gotten to the hospital when she did.
The infant was transported to Cook Children’s Medical Center in Fort Worth, where she remains on life-support.
While serving a search warrant at the home, officers found drug paraphernalia and a small amount of suspected heroin, methamphetamine, marijuana, and pills.
Harbour, Bradley, and Smock were charged with injury to a child-serious bodily injury.
Harbour's bond was set at $100,000.
Bradley and Smock's bond were set at $50,000.
Bradley bonded out.
