Sioux Falls Man Sentenced to 15 Years in Federal Prison for Production of Child Pornography

SIOUX FALLS - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Karen E. Schreier has sentenced a man from Sioux Falls, South Dakota, convicted of Production of Child Pornography. The sentencing took place on September 8, 2025.

Amir Kalomo Mulamba, age 29, was sentenced to 15 years in federal prison, followed by five years of supervised release, and ordered to pay a special assessment to the Federal Crime Victims Fund in the amount of $100. Upon release from federal prison, Mulamba must register as a sex offender.

Mulamba was indicted by a federal grand jury in November 2021. He pleaded guilty on June 16, 2025.

The conviction stemmed from incidents between May 30, 2021, and June 25, 2021, when Mulamba used Snapchat to meet and coerce a 14-year-old female living in Utah to engage in sexually explicit conduct, record that conduct, and provide those recordings and images to Mulamba. The coercion included convincing the minor female to record and send to Mulamba a video of her penetrating herself with a foreign object. In exchange for the videos and images, Mulamba promised to buy the victim a cellular phone.

This case was investigated by Homeland Security Investigations and the Sioux Falls Police Department. Assistant U.S. Attorney Elizabeth A. Ebert-Webb prosecuted the case.

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 the U.S. Attorneys' Offices and the DOJ's Child Exploitation and Obscenity Section, Project Safe Childhood marshals federal, state, and local resources to locate, apprehend, and prosecute individuals who exploit children, as well as identify and rescue victims.

Mulamba was immediately remanded to the custody of the U.S. Marshals Service.
