Calling it a "painful moment in our history," University of Michigan Health System CEO Ora Pescovitz wrote in a blog post Monday that the university has "identified significant problems" with the way it handled an allegation last May that child porn was found at U-M Hospital. Recently unsealed court records show that a physician found an illegal image May 23, spoke with her supervisors, and met with hospital security officials and the Office of the General Counsel about it. However, the incident wasn't reported to police until Nov. 21, when a hospital security official came forward.
