ANN ARBOR (AP) — University of Michigan leaders said Friday that they plan to stay the course with their own investigation into allegations a deceased team doctor molested hundreds of people going back decades, declining the state attorney general’s offer to get involved and angering lawyers for the accusers, who described the school’s stance as shameful.

In response to Michigan Attorney General Dana Nessel saying Thursday she would investigate the claims against Dr. Robert E. Anderson and how the school dealt with them, but only if the school fully cooperates, the university released a statement Friday from its president, Mark Schlissel, and eight-member board of regents.

“We have met with, and sought counsel from, survivors, doctors and mental health experts and believe we are overseeing a process that will ultimately serve as the best course of action for the survivors and University community,” the school said.

The response didn’t mention Nessel, but lawyers for some of Anderson’s accusers wasted no time in offering their take on what the school was saying.
