A local federal prosecutor, who has a well-earned reputation for
successfully prosecuting cases investigated by U.S. Immigration and Customs
Enforcement's (ICE) Homeland Security Investigations (HSI) in Boston, received
top honors from the agency Friday, January 18, 2013. He was honored for his
outstanding professional achievements as a leading member of the U.S.
Attorney's Office for the District of Massachusetts.
Assistant U.S. Attorney Michael Yoon was recognized for his contributions to
federal child exploitation prosecutions, particularly Operation Holitna. His
work with HSI, focused on child exploitation investigations, has resulted in
the arrests of numerous child predators worldwide.
Operation Holitna is an ongoing HSI-led investigation that originated in
Boston in 2010. In
November 2010 the U.S. Attorney's Office for the District of Massachusetts and
HSI Boston arrested Robert Diduca on child pornography production charges. He
was convicted and subsequently sentenced in June 2012.
Forensic analysis of
Diduca's computer led investigators to the
Netherlands where a Dutch national
was arrested and charged with production, distribution and possession of child
pornography, as well as the sexual abuse of 87 minors. Since the launch of this
worldwide operation, more than 160 children have been rescued and 50
perpetrators arrested worldwide.
"The grim reality is that online child exploitation is a very real part
of our modern lives and it is going on throughout the world, right now, on a
grand scale," said ICE Director John Morton. "Thanks to the expertise
of Assistant U.S. Attorney Michael Yoon - who has demonstrated his unwavering
commitment to prosecuting these types of cases - child predators are being brought
to justice each and every day. Michael's dedication to the cause ultimately led
to the discovery of the largest case of child exploitation in Dutch
history."
"During his time in the Major Crimes Unit, Michael demonstrated
unwavering commitment to prosecuting child exploitation cases," said U.S.
Attorney Carmen M. Ortiz, District of Massachusetts. "It was Michael's
extraordinary ability to balance the complexity of a constantly expanding case
- that demanded the collaboration of national and international law enforcement
agencies - which led to the prosecution and sentencing of Robert Diduca and a
vast network of online child sex offenders. We are fortunate to have such a
passionate and dedicated prosecutor working on our team."
His expertise on prosecuting these cases continues to this day, as Operation
Holitna continues to arrest pedophiles who are sexually abusing children and
producing child pornography in Europe, Asia and
North
America.
HSI special agents, who have worked closely with Assistant U.S. Attorney
Yoon for years stated:
- "There was never a day
or night that Michael wouldn't respond to calls from HSI Boston for
assistance - even at 2:30 in the morning. His efforts were constantly
going above and beyond the normal expectations special agents have of
federal prosecutors."
- "He is the most
responsive assistant U.S.
attorney I have ever worked with in my career. When working with Mike,
there was never any doubt we were one team."
- "Mike has a unique blend
of legal experience - with an investigator's mindset - which fit perfectly
with the goals of Operation Holitna. Without his guidance and support, I
am certain that we wouldn't have achieved the many successes over the past
two years."
Assistant U.S. Attorney Yoon has been assigned to the U.S. Attorney's Office
for the District of Massachusetts since 2010. From 2005 to 2010, Yoon worked as
a trial attorney in
Washington
for the Department of Justice's Child Exploitation and Obscenity Section. He
has been recently reassigned to the U.S. Attorney's Organized Crime Drug
Enforcement Task Force.
Operation Holitna, and other New England-based investigations that protect
children from sexual predators, including those who travel overseas for sex
with minors, Internet child pornographers, criminal alien sex offenders and
child sex traffickers, are run out of HSI's state-of-the-art forensic
laboratory in
Boston.
This facility, located in the John F. Kennedy Federal Building, assists
federal, state and local law enforcement authorities in New England with a wide
range of forensic investigative support in cases that are often complex, and
require significant examination and analysis.
The forensic lab prepares investigators as they team with other state and
local investigative experts, as well as prosecutors throughout
New England. Several other federal, state and local law
enforcement authorities have expressed their support of efforts to strengthen
investigative techniques to remain competitive with the ever-changing world of
scientific technology. The lab employs the latest technology to collect
evidence and track the activities of individuals and organized groups who
sexually exploit children through the use of websites, chat rooms, newsgroups
and peer-to-peer trading. As Internet access continues to expand, the forensic
lab brings the full range of HSI computer and forensic assets together in a
single location to combat such Internet-related crimes.
These types of investigations are part of Operation Predator, a nationwide
HSI initiative to protect children from sexual predators.
