United States of America v. Zam Lian Mung

Rapid City, SD - Rapid City Man Sentenced to 10 Years in Prison for Attempted Sex Trafficking



A Rapid City, South Dakota, man convicted of Attempted Commercial Sex Trafficking of Children and Attempted Enticement of a Minor Using the Internet following a federal jury trial, was sentenced.



Zam Lian Mung, age 30, was sentenced to 10 years in federal prison, followed by 5 years of supervised release, and was ordered to pay a $200 special assessment to the Federal Crime Victims Fund.



Mung was one of seven men who were arrested and federally indicted as a result of an undercover sex trafficking operation conducted during the 2018 Sturgis Motorcycle Rally, targeting persons willing to pay to have sex with minors obtained through the Internet. The conviction stemmed from Mung communicating with someone he believed to be associated with a 15-year-old girl, but who was in fact an undercover agent, for the purpose of arranging a meeting to engage in sexual acts with the minor.



The undercover operation and arrests were a joint effort between the South Dakota Division of Criminal Investigation, the Department of Homeland Security, the Federal Bureau of Investigation, the Rapid City Police Department, and the Pennington County Sheriff’s Office. Assistant U.S. Attorney Sarah Collins prosecuted the case.



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