NORWALK - A Westport mom pleaded not guilty to all charges today after she was accused of driving drunk with her children in the car and causing an accident.

According to investigators, Lana O'Brennan's blood-alcohol level was four times the legal limit when she slammed head-on into another vehicle last month on Main Street in Westport. No one was seriously hurt, but O'Brennan's two young children were in the car with her.

At her hearing, a visibly emotional O'Brennan was upset upon seeing cameras in the courtroom. Her lawyer raised an objection, which was denied by the judge. She is due back in court on June 14.
