Erin Hughes, 18, returned to a Skokie courtroom one day after she was released from jail on bond. She is accused of hitting Sarah Goone, 16, with her car Friday at New Trier High School in Winnetka and leaving the scene of the accident.
During the brief court appearance, results of a toxicology report were read. Marijuana was found in Hughes' system, officials said, but more tests would be needed to determine how much. Officials said more charges could be filed against Hughes.
"I'm sure they will provide any charges they think is appropriate we will deal with it when they do," said Barry Spector, Hughes' attorney.
Because other drugs and alcohol were not found in the toxicology report, Cook County Judge Marcia Orr said she was comfortable with Hughes taking off an electronic monitor.
While walking out of court, Hughes told the media her prayers were with the victim, who remains hospitalized in stable condition with a severe head injury.
"All you people need to know is that I'm praying for Sarah. I hope she gets better," said Hughes.
It's the first time Hughes has spoken publically since the crash.
"She is overwhelmed by that. And it's not just her. It's her family. It's her friends. Their only concern is that this young lady make a complete recovery," said Barry Spector, defense attorney.
Hughes will have to undergo periodic drug testing, including a test Thursday. Her next court date is June 14.
Hughes allegedly confessed to police to smoking marijuana the night before the crash, which prompted the judge to set a $500,000 bond. After six days in jail, Hughes was released from the Cook County Jail Wednesday after an anonymous donor provided the $50,000 bail needed to get her out of jail.
