MORGANTOWN, W.Va. (AP) -- Federal documents filed by a NASA fraud investigator say a former head of the Mine Safety and Health Administration and the Catholic college in West Virginia where he works used millions of grant dollars from the space agency for personal gain and the school's benefit.

The affidavit by the NASA Office of Inspector General targets Davitt McAteer and Wheeling Jesuit University. It shows investigators believe McAteer and the school fraudulently billed from 2005 through 2011 for everything from McAteer's $230,000 salary to cellphones, computers and technical support.

The allegations were made to obtain search warrants in a criminal investigation of the mine safety expert and his alma mater.

McAteer's attorney did not immediately return a message for comment. A Wheeling spokeswoman said she hadn't seen the document and couldn't comment.
