Greg Allen Henke, 41, pleaded guilty to sexual exploitation of a child and to possession of child pornography Monday, according to Acting U.S. Attorney Robert J. Troester.

On May 31, 2021, FBI agents arrested Henke in Oklahoma City after he met with an undercover agent to attempt to engage in sexual activities with children. He has been in federal custody since his arrest.

Prior to his arrest, Henke was employed at Highland Park Elementary School in Mid-Del school district.

On June 1, 2021, a federal grand jury returned an Indictment against Henke, charging him with attempted receipt of child pornography and attempted coercion and enticement of a minor. That Indictment alleged that on or about May 10, 2021, Henke knowingly attempted coercion and enticement of a minor. That Indictment alleged that around May 10, 2021, Henke knowingly attempted to receive child pornography using a means and facility of interstate and foreign commerce.

That Indictment further alleged that, between April 1, 2021 and May 13, 2021, Henke used a cell phone and the internet to attempt to persuade, induce, entire and coerce a minor to engage in sexual activity.

On Sept. 7, 2021, a federal grand jury returned a Superseding Indictment against Henke. It added to the original Indictment one charge of possession of material containing child pornography and two charges of production of child pornography. Specifically, the Superseding Indictment alleged that between 2019 and 2021, Henke used two minor students at Highland Park Elementary School to engage in sexually explicit conduct.

It also alleged that Henke used his cellphone to capture the sexually explicit conduct.

At a plea hearing today, Henke pleaded guilty to one count of producing child pornography using a student while he was working at Highland Park Elementary School. Henke also pleaded guilty to possessing child pornography on several electronic devices. As part of a plea agreement, the United State agreed to dismiss the remaining charges at his sentencing.

Henke’s sentencing is expected to take place in 90 days. He faces a maximum penalty of 50 years in federal prison, in addition to a term of supervised release for at least five years and up to a life sentence. The guilty plea to producing child pornography carries a mandatory minimum term of 15 years in federal prison.
