COLUMBUS, Ohio (AP) — Ohio State University has been billed about $1.5 million and counting for the investigation into a team doctor accused of sexual misconduct against scores of athletes and other men.

A list of related invoices provided by the university shows most of that is from Perkins Coie, the law firm hired to investigate claims raised this year about the now-deceased physician, Richard Strauss.

The list reflects invoices only through Aug. 17. The investigation continues, and three related lawsuits are pending.

At least 145 former students have given investigators firsthand accounts of alleged sexual misconduct by Strauss between 1979 and 1997. The allegations involve athletes from 16 sports, plus the student health center and his off-campus medical office.

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