New information could help the woman charged in a deadly school bus accident. Her attorney said there is new DNA evidence that could clear Olga Franco as the driver of a van that crashed into a school bus in February killing four children. At a hearing Friday, attorneys for Franco said they have DNA evidence that proves a man was driving the van. They said DNA taken from the driver's side airbag shows it came from an unidentified male. Franco has told police that her boyfriend, Francisco Sangabriel-Mendoza, was driving the van. Police have yet to locate him.
