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

Tampa, Florida – U.S. District Judge Charlene E. Honeywell has sentenced Nathan A. Madsen (37, Tampa) to 17 years and 6 months in federal prison, followed by a life term of supervised release, for enticing a child to produce child pornography and for possessing child pornography. The Court also ordered Madsen to forfeit his vehicle and multiple electronic storage devices that had been used in the commission of the offenses. Madsen pleaded guilty on February 3, 2017. Prior to his arrest, he had worked as a music professor at the University of Tampa.


According to court documents, Madsen responded to an online advertisement for prostitution services posted on Madsen requested and negotiated the price to have sex with a 14-year-old-girl. Unbeknownst to him, the message had been posted by agents from U.S. Immigration and Customs Enforcement’s Homeland Security Investigations. In an attempt to verify the existence of the minor, Madsen asked for her picture, spoke to “her” on the phone, withdrew money from the ATM and drove to the designated meeting location. Madsen met with and paid an undercover special agent $140 to have sex with the minor.


After his arrest, agents executed a search warrant at Madsen’s apartment and seized multiple electronic devices. Forensic analyses of his cellphone and tablet revealed that from at least May 2015 and continuing through July 2015 Madsen engaged in a series of sexually explicit online conversations with a 16-year-old girl. During this time, he persuaded, induced, and enticed the child to produce and transmit explicit images and videos for his personal benefit. At the time of his arrest, Madsen had 61 explicit images and 14 videos of the child, some of which depicted violent, sadistic or masochistic conduct.


“Our HSI special agents, in partnership with the Tampa Police Department, have prevented this predator from harming more children,” said Ivan J. Arvelo, acting special agent in charge of HSI Tampa. “This investigation demonstrates that child exploitation continues to be a threat that can’t be ignored. Today’s sentencing sends a message that HSI is committed to the investigation and prosecution to the fullest extent of the law of individuals who engage in any heinous crime against our children.


This case was investigated by U.S. Immigration and Customs Enforcement’s Homeland Security Investigations and the Tampa Police Department. It was prosecuted by Assistant United States Attorneys Stacie B. Harris and Lisa M. Thelwell.


This case was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 by the Department of Justice to combat the growing epidemic of child sexual exploitation and abuse. Led by United States Attorneys’ Offices and the Criminal Division’s Child Exploitation and Obscenity Section (CEOS), Project Safe Childhood marshals federal, state, and local resources to locate, apprehend, and prosecute individuals who sexually exploit children, and to identify and rescue victims.
