Former Allegheny English Professor Kirk Nesset faces at least five years in federal prison following his guilty plea in Erie federal court on April 6.

Charged with possession, distribution and receipt of child pornography, Nesset had originally entered a plea of not guilty on Oct. 15, 2014.

U.S. District Judge David S. Cercone heard the change of plea. Cercone set the sentencing date for Aug. 10, 2015; however, he agreed to let Nesset report to federal prison before his sentencing hearing, according to news reports. Nesset is free on an unsecured $10,000 bond while wearing an electronic monitor.
