WINONA, Minn. -

A Winona State University professor is fired after allegedly having inappropriate contact with 16 students.

Bill Murphy, Dean of the College of Business, was fired in September of last year.

Students and parents were told of the firing Friday in a letter from university president Scott Olson. Olson says Murphy was in possession of inappropriate pictures of some male students and was engaging in sexually-oriented discussions with them.

The university president says the behavior was "clearly inappropriate."

Officials were tipped off after an anonymous student complaint. An investigation was started right away and Murphy was fired a couple weeks later.

Olson calls this incident out of character for the university. "So out of line with our values and norms, why it won't be tolerated, and why activities such as this is going to result in swift and decisive action just as this did, student well being is our paramount concern."

The university waited until now to tell people as part of the termination agreement with Murphy.

Right now, the Winona District Attorney's office says there are no criminal charges being filed.

Winona police investigated material on Murphy's school-issued computer, but found nothing criminal.
