THE ACREAGE, Fla. - The driver suspected of hitting a 9-year-old in The Acreage on March 4 is in custody, according to the Palm Beach County Sheriff's Office.
Dynasdy Williams turned herself in after a warrant was issued for her arrest, according to the sheriff's office.
Melanie Ponce De Leon, a student at Golden Grove Elementary, was struck while she was walking home from a bus stop.
Williams told an investigator that she thought that she had hit a sign and did not realize she struck a child until one of her two children in her car started crying and she returned to the scene, according to a probable cause affidavit.
She also admitted that she takes prescription medication and that she had a shot of alcohol earlier in the day, according to the report.
The sheriff's office said results of a blood test later revealed that Williams had an alcohol level of 0.118 as well as Alprazolam (Xanax) in her system.
Williams, according to accident reports and school board information, used to work as a bus driver for Palm Beach County Public Schools. She was involved in a school bus crash in January.
Williams worked as a temporary bus driver from Thanksgiving of last year until Jan. 21.
Police reports show she was driving a school bus when she rear-ended Nova Ballard of Royal Palm Beach who was stopped at a red light on Jan. 15.
A family member says Melanie had two more surgeries last week to remove fluid from her brain and is back on a feeding tube.
The Golden Grove Elementary PTO has helped raise money for the child's medical expenses.
Williams is being held at the Palm Beach County Jail. She's facing a charge of D.U.I. Crash Causing Serious Bodily Injury.
