A Wichita man who worked briefly as a special education paraeducator in the Lawrence school district pleaded guilty Monday in Sedgwick County District Court to four counts of sexual exploitation of a child.

Gregory Phillip Nicks, 33, who is also a former Wichita police officer and a former Kansas University football player, was arrested in 2011 along with a female co-defendant, Luz Coronado. The arrests came after it was discovered Nicks had sent Coronado lewd photographs of a 14-month-old girl by email.

Coronado was convicted in August of four counts of sexual exploitation and one count of aggravated indecent liberties with a child.

KAKE-TV in Wichita reported that Nicks entered the guilty pleas in exchange for the state dropping two counts of aggravated indecent liberties with a child.

According to Lawrence school district records, Nicks was employed as a special education paraeducator at South Junior High from April 18 to May 25, 2005. District spokeswoman Julie Boyle said records indicate he resigned his position after that.

Nicks played football at KU in 2001 and 2002 as an offensive lineman and center.

Paraeducator positions do not require a teaching license. Lawrence district officials could not say whether he held a teaching license or whether he had worked in any other districts.

Sentencing is scheduled for May 3 before Sedgwick County District Judge Terry Pullman.
