William Lee Hunter Jr., 42, pleaded guilty Wednesday to a felony count of possessing child pornography in accordance with a plea agreement that requires supervised probation but not prison time.

Tulsa County Special Judge Carlos Chappelle ordered Hunter -- who was free on bond -- to pay a $500 fine, a $250 victims compensation assessment and court costs.

Hunter said that on July 2 he "watched and viewed child pornography on a public library computer," a court record shows.

Tulsa Public Schools records show that Hunter taught during the 2006-07 school year at Springdale Elementary School, 2510 E. Pine St.

Hunter, who had been a TPS employee since 2002, submitted his resignation effective at the end of last school year, a school official said.

Police said a security guard noted suspicious behavior by Hunter at the Central Library and "watched his activity from a covert position." The guard saw Hunter view child pornography videos and called police, an investigator reported.

Detective W. Scott Gibson's affidavit states that when interviewed, Hunter said the "child pornography website and videos were already opened" when he sat down at an open computer. Hunter admitted that he browsed the Web site and viewed the videos, according to Gibson.

Defense attorney Kevin Adams said the case was resolved under a statute that does not require sex-offender registration.

The outcome gives Hunter a felony conviction, and "he will not be able to teach again," Adams said Wednesday.

A library official previously said a filter system protects the computers but cannot catch everything in the ever-evolving Internet.
