Rhode Island State Police have opened an investigation into whether any criminal violations occurred when a 5-year-old girl was left unattended inside a school bus in Westerly.
Police launched the probe last week after the school district's former director of transportation lost track of the girl on Sept. 21.
Peter Denomme resigned this month. He had worked for Westerly Public Schools since 2009.
Capt. John Allen says troopers will begin conducting interviews next week.
Superintendent Roy Seitsinger Jr. says the district will fully cooperate with the investigation.
An attorney representing the girl's family requested that state police investigate because the potential criminal acts occurred in multiple towns.
