An Antioch woman accused of shaking her 9-month-old baby hard enough to cause bleeding in the child’s brain and retina turned herself in at county jail this afternoon, Antioch police Sgt. Diane Aguinaga said. Georgette Duperval, 27, has been charged with felony child abuse causing great bodily injury and was booked into jail on $150,000 bail. She had arranged through her lawyer to turn herself in as soon as the charges were filed. The charges stem from two separate incidents, the first of which happened on June 9 when Duperval’s daughter was rushed to Children’s Hospital in Oakland.Doctors discovered that child had bleeding in her brain,Aguinaga said.Duperval allegedly told police that the girl had fallen off the bed, but doctors later determined that the only way the baby could have received that type of injury was if she had been in a high-speed car crash or she was shaken, Aguinaga said.The child was released from the hospital on June 11, but later that day, she was taken back to the hospital for treatment of retinal hemorrhaging, or bleeding in the back of the eyes, a symptom often associated with long-term child abuse and shaken baby syndrome.The baby was in the hospital for more than a week being treated for her injuries and then released into protective custody.According to Aguinaga, doctors said they do not believe the child, who is now 10 months old, has suffered any permanent damage.
