Contact: Ultan Doyle, Assistant Attorney General, (802) 828-5512

Attorney General Thomas J. Donovan announced today that four men were arrested during the week of April 17th for possession/promotion of child pornography. The arrests were made as result of Operation Peer Review. Operation Peer Review, which was conducted by Vermont’s Internet Crimes Against Children Task Force (VT-ICAC), involved undercover investigations of peer-to-peer networks. Peer-to-peer networks utilize file sharing software to share electronic files with others anywhere in the world. These networks are sometimes exploited by child predators to obtain and share files depicting child pornography.

In Operation Peer Review, VT-ICAC’s investigators operated undercover online and obtained child pornography from suspects on peer-to-peer networks. The operation culminated in the execution of five search warrants over a three-day period by members of VT-ICAC to identify these suspects. These searches resulted in the arrest of the following individuals:

Shane Martensen DOB: 04/13/73 of Burlington, Vermont.
Lukas Vopenka DOB: 10/18/89 of South Burlington, Vermont.
Brendan Sullivan DOB: 02/26/96 of Milton, Vermont.
Suin Sun DOB: 07/07/88 of Winooski, Vermont.

These individuals now face either federal or state charges for possession or promotion of child pornography. The Attorney General emphasizes that these individuals are legally presumed innocent of the charges until their guilt is proven beyond a reasonable doubt through the court process.

VT-ICAC was formed in 2008. The Vermont Attorney General’s Office assumed responsibility for managing VT-ICAC in October of 2015.  Since October of 2015, the Task Force has performed 664 investigations, received 577 Cybertips from the National Center for Missing and Exploited Children and arrested 87 individuals for crimes against children. VT-ICAC also works extensively to educate Vermont communities about internet safety. In the past three years, VT-ICAC conducted 1667 educational forums around the state.

To assist in locating evidence as small as a micro sd card (a device as small as a fingernail) VT-ICAC obtained an electronic detection K9, named Mojo. Mojo, a yellow Labrador, is one of just a few of these dogs currently in use across the country. Mojo’s deployment has been successful; since January of this year he has been in use at search warrants across the state and has led to the recovery of concealed evidence.

Operation Peer Review was a collaborative effort involving the Vermont Attorney General’s Office, the Vermont State Police, Homeland Security Investigations, Vermont United States Attorney’s Office, Burlington Police Department, South Burlington Police Department, Winooski Police Department, Bristol Police Department, Chittenden Unit for Special Investigations, Orange County Sheriff’s Department, and University of Vermont Police Services.
