COLUMBUS (AP) — A law firm hired by Ohio State University to investigate a former team doctor accused of sexual misconduct against athletes and students hopes to wrap up its fact finding by the end of the year.

The investigators told the university’s governing board Thursday about 150 former students have given firsthand accounts of alleged sexual misconduct by the now-deceased doctor.

The law firm says the allegations against Richard Strauss cover a time from 1979 through 1997.

Strauss killed himself in 2005. His relatives have said they’re shocked by the allegations.

The independent investigators say they are also looking into whether any university employees at the time knew about the allegations against Strauss.

They say they have talked with a number of former university employees, but some have not cooperated.
