Eleven South Dakotans face federal charges of attempted enticement of a minor using the internet after an online sting that ran March 7th through March 12.
Flandreau native, U.S. Attorney Ramsdell, led the investigation, as part of Project Safe Childhood. The nationwide initiative is designed to combat the growing epidemic of child sexual exploitation and abuse. The operation was conducted by Homeland Security Investigations (HSI) St. Paul, the Internet Crimes Against Children Task Force, the South Dakota Division of Criminal Investigation, the Sioux Falls Police Department, the Watertown Police Department, the Tea Police Department, the Rapid City Police Department, the Minnehaha County Sheriff’s Office, the Lincoln County Sheriff’s Office and the South Dakota Highway Patrol.
The following individuals from Sioux Falls were arrested and federally charged:
●Kyle Dean Bult, age 38.
●Kalvin Michael Frankus, age 37.
●Hunter Hill, age 22.
●Stacy Shannon Hoover, age 56.

●Ryan Nigro, age 32.
●Jorge Manual Rodriguez-Marroquin, age 47.
●Dylan Ryan, age 24.
●Gerber David Santos Gonzalez, age 25.
●William Danery Sebastian, age 33.
●Southy Thepmontry, age 69.
●Carter Lee Tyree, age 20.
If convicted, the minimum penalty upon conviction is 10 years and a maximum of life in federal prison and up to a $250,000 fine.
“This operation demonstrates the unsettling reality that here in our own communities, there are individuals using the internet to target young girls and boys for sex,” said Ramsdell.
“We are grateful to our federal, state and local law enforcement partners, who regularly collaborate to safeguard children across South Dakota. May it serve as a stark reminder to parents, guardians and caretakers that the internet can be a very dangerous place for children, particularly when their activity is left unmonitored.”
