A Sioux Falls man has been sentenced to 15 years in federal prison for producing child pornography, according to an announcement from U.S. Attorney Alison J. Ramsdell. The sentencing was handed down by U.S. District Judge Karen E. Schreier on September 8, 2025.
Amir Kalomo Mulamba, 29, will also serve five years of supervised release and must pay a $100 special assessment to the Federal Crime Victims Fund. Upon his release from prison, Mulamba is required to register as a sex offender.
Mulamba was indicted by a federal grand jury in November 2021 and pleaded guilty on June 16, 2025.
According to court documents, between May 30 and June 25, 2021, Mulamba used Snapchat to contact and coerce a 14-year-old girl living in Utah into engaging in sexually explicit conduct. He instructed her to record these acts and send him the recordings and images. One incident involved convincing the minor to create a video of herself penetrating herself with a foreign object. In exchange for these materials, Mulamba promised the victim he would buy her a cellular phone.
The investigation was conducted 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," according to the press release from Ramsdell's office. "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."

Following sentencing, Mulamba was immediately remanded into custody by the U.S. Marshals Service.
