Police said a forensic investigation had shown the driver, one of two aboard, was at the wheel when the bus carrying 56 people ploughed into a bridge pillar on January 20th and burst into flames on a northern Italian motorway near the city of Verona.
The driver, charged with a new offence of "vehicular homicide," involving reckless conduct or negligence leading to serious injury or death, was only identified by his initials.
In all, 11 youngsters died along with five adults, including the other driver.
