CHICAGO -- A Chicago Public Schools teacher is charged in the hit-and-run crash that injured two young sisters outside their Portage Park school this week. Among the charges, a DUI.

“I saw my sister laying there on the other side of the street, and I remember I tried to get up, but I couldn’t, and it was just really scary, ‘cause I just saw her laying there and I thought she was dead," said Jazmine Oquendo.

Little Ava certainly took the worst of it, and she didn't feel like talking about it Thursday night.

But witnesses, including her brother, describe seeing the 7-year-old’s tiny body flying through the air Tuesday morning. She and her big sister were in the crosswalk outside their school just a couple of blocks from home

“I’m glad that they’re alive, breathing and they’re home with us," said mom Christina Frangos. "I would hate for any other parent to go through this. Being at work, hearing that something happened to your child and you’re not there to comfort them."

Witnesses say the driver got out of his car for a minute, saw the girls lying in the street, then tried to flee. He was stopped a short distance away.

Matt Lucchini is charged with DUI, leaving the scene of an accident, failing to yield to pedestrians in a crosswalk and negligent driving.

Chicago Public Schools confirms he’s a physical education teacher at nearby Locke Elementary. While a spokesman told WGN he can’t comment on an ongoing investigation, he said CPS "takes allegations of unlawful activity by its employees very seriously.”

The girls, rushed to Lutheran General Tuesday, are recovering at home now.
