Lincoln Man Sentenced to 60 Years for Production and Possession of Child Pornography

For Immediate Release
U.S. Attorney's Office, District of Nebraska

United States Attorney Susan Lehr announced that Amikhet En Maati, also known as Warren Coker, 53, of Lincoln, Nebraska, was sentenced on May 20, 2024, in federal court in Lincoln for two counts of production of child pornography concerning two separate victims, two counts of committing production of child pornography while on the Sex Offender Registry, and one count of possession of child pornography. Senior United States District Judge John M. Gerrard sentenced Maati to a total of 720 months’ (60 years’) imprisonment. There is no parole in the federal system. He was further sentenced to a lifetime of supervised release following his release from prison. Additionally, Maati is ordered to pay $6,000 to a federal fund established to assist victims of child exploitation crimes. 

On September 9, 2022, Lincoln Police Department (LPD) received a report regarding the sexual abuse of a minor female where Maati was the subject. A search of the residence was conducted and a cellphone belonging to Maati was seized. Around that same time, LPD determined that Maati was also the subject of a recent tip made to the FBI. A forensic examination was completed on Maati’s cellphone. Law enforcement discovered multiple child exploitation videos of minor Victim 1 and one video of minor Victim 2. Maati uploaded and distributed these videos to a cloud-storage website where his friend, who was another registered sex offender, had access to them. Further review of Maati’s cloud-storage account revealed additional child exploitation videos of each of the victims.

Maati was charged in April 2023 and proceeded to a bench trial before Senior District Judge Gerrard in February of this year. He was found guilty on all counts.

Maati was previously convicted on or about January 2, 1997, for Attempted Sex Assault of a Child in Douglas County District Court, Nebraska, and on or about July 1, 1999, for one count of Second-Degree Sexual Assault and one count Sexual Assault of a Child in Sarpy County District Court, Nebraska. 

This case was brought as part of Project Safe Childhood, a nationwide initiative to combat the growing epidemic of child sexual exploitation and abuse launched in May 2006 by the Department of Justice. Led by United States Attorneys’ Offices and the Criminal Division's Child Exploitation and Obscenity Section (CEOS), Project Safe Childhood marshals federal, state and local resources to better locate, apprehend and prosecute individuals who exploit children via the Internet, as well as to identify and rescue victims.
