Lincoln Man Convicted for Child Pornography Charges

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

United States Attorney Susan Lehr announced that Amikhet En Maati, formerly known as Warren Coker, 52, of Lincoln, Nebraska, was found guilty by a bench trial on February 22, 2024, in federal court in Lincoln, Nebraska for two counts of production of child pornography concerning two separate victims, two counts of committing the production of child pornography offenses while on the Sex Offender Registry, and one count of possession of child pornography. Senior United States District Judge John M. Gerrard presided over the bench trial and set sentencing for May 20, 2024.

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 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 of Sexual Assault of a Child in Sarpy County District Court, Nebraska. Due to these prior convictions, Maati now faces a mandatory sentence of at least 45 years imprisonment based on today’s guilty verdict.

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 U.S. Attorneys’ Offices and 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.
