PROVO, Utah (KUTV) — The first man to be taken into custody in the aftermath of the Charlie Kirk assassination at Utah Valley University in September entered a guilty plea earlier this week.

George Hodgson Zinn, 71, pleaded guilty to third-degree felony obstruction of justice and two counts of second-degree felony sexual exploitation of a minor.

He faces up to 15 years in prison for each of the second-degree felony charges and up to five years in prison for the obstruction charge.

Zinn was first taken into custody immediately after the Charlie Kirk shooting after he was found on campus shouting, "I shot him, now shoot me." According to documents, he later admitted to not being behind the shooting but he wanted to draw attention away from the real shooter.

He allegedly made comments saying he was glad that he had said he shot Kirk so the real shooter could escape.

Officers originally booked Zinn on a second-degree felony charge of obstruction of justice. However, as part of their investigation, agents with the FBI and Utah State Bureau of Investigation went through Zinn's phone, where they reportedly found 20 sexually explicit images of children and "several very graphic sexual text threads" where Zinn shared images with other people.

Zinn was then charged with four counts of second-degree felony sexual exploitation of a minor.

As part of his guilty plea, prosecutors agreed to drop two of the sexual exploitation of a minor charges and lessen the obstruction charge to a third-degree felony.
