A 49-year-old Gillett man arrested in an internet sex sting in September pleaded not guilty Wednesday to the allegations against him.

Keith Nelson Luebke is faced with two charges — internet stalking of a child, a Class Y felony, and sexual solicitation, a Class B misdemeanor — following his Sept. 28 arrest. He is currently free on a $50,000 bond.

A waiver, filed by the Jams Law Firm on Wednesday, maintains Luebke’s innocence and requests a waiver of formal arraignment.

"I, Keith Luebke, the undersigned Defendant in the above-style cause, hereby voluntarily and with advice of counsel, waive formal arraignment on the charges now pending against me," the motion filed by William O. "Bill" James Jr. reads.

A plea an arraignment hearing is scheduled 9 a.m. Monday in Luebke’s case.

In his motion filed with the Faulkner County Circuit Clerk, he pleaded not guilty to the allegations against him and asks that a pretrial hearing be set in his case.

"I waive formal arraignment and request that the Court enter my plea of not guilty to the charges against me," the motion reads. "I understand that my bond is to guarantee my appearance before this Court; that I am to keep in contact with my attorney who will be notified of all times I am to appear before the Court; and that I am required to appear before the Court at those times. If I fail to appear in Court, my bond may be forfeited and a warrant may be issued for my arrest."

According to a probable cause affidavit, the sheriff’s office reached out to Luebke after he posted a suspicious online ad seeking a "younger" female.

An investigator messaged Luebke posing as a 15-year-old girl.

According to the affidavit, Luebke made arrangements to meet up with the investigator’s undercover profile in Mayflower, noting he would bring condoms and $100 "to pay the UC for either sexual intercourse or oral." Luebke told the undercover investigator posing as a 15-year-old girl that he would arrive at the predetermined spot around 9:15 a.m. Friday in a white SUV.

Investigators blocked in Luebke’s vehicle when he arrived at the predetermined location at 9:30 a.m.

According to the affidavit, Luebke admitted to "discussing sexual contact and paying for that contact" with a girl he met online. However, he said he would not have followed through with those plans.

Deputies seized multiple firearms, loaded magazines, multiple doses of Viagra, condoms, more than $600 in cash and "large quantities of other prescription medications" as evidence following Luebke’s arrest.
