A former Massachusetts attorney general has been hired to conduct an independent investigation into allegations of sexual abuse at a prestigious Rhode Island boarding school.

More than 40 former students at St. George's School in Middletown have alleged they were molested or raped there, mostly in the 1970s and '80s.

Last month, the school said an investigation found 26 students had been sexually abused by six former employees and several former students. The school acknowledged it didn't report abusers to authorities at the time and apologized.

The school agreed to do a new investigation after many victims questioned the impartiality of the first one, which was led by the law partner and spouse of the school's attorney.

Ex-Massachusetts Attorney General Scott Harshbarger has been hired. He also worked as a state prosecutor.
