Rapid City Man Found Guilty of Attempted Commercial Sex Trafficking of Children

United States Attorney Ron Parsons announced that Zam Lian Mung, age 29, was found guilty of Attempted Commercial Sex Trafficking of Children following a federal trial in Rapid City, South Dakota.

The charge carries a mandatory minimum of 10 years up to life in federal prison and/or a $250,000 fine, 5 years up to lifetime supervised release, and a $100 special assessment to the Federal Crime Victims Fund.

Evidence at trial established that on August 7, 2018, Mung responded to a prostitution advertisement on posted by Division of Criminal Investigation undercover agents, which purported to offer young girls for sex. Following several messages with a person Mung believed to be associated with a 15-year-old girl, but who was in fact an undercover agent, he proceeded to negotiate the time and place they would meet, along with the $150 he would pay to engage in sex acts with the minor.

The undercover operation and arrest was 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 and tried the case.

A sentencing date has not been set.  Mung was remanded to the custody of the U.S. Marshals Service pending sentencing.
