Cybertip led to investigation, discovery of images

AUGUSTA, GA:  A Columbia County, Ga., man has been sentenced to federal prison after admitting he possessed images of children being sexually exploited.

Mark Christopher Greene, 46, of Appling, Ga., was sentenced to 102 months in prison after pleading guilty to Possession of Child Pornography, said David H. Estes, U.S. Attorney for the Southern District of Georgia. U.S. District Court Chief Judge J. Randal Hall also ordered Greene to pay $18,000 in restitution, to serve 15 years of supervised release and register as a sex offender after completion of his prison term.

There is no parole in the federal system.

“Protecting our most vulnerable citizens is an essential element of public safety,” said U.S. Attorney Estes. “We commend our vigilant law enforcement partners for identifying and shutting down digital predators.”

The investigation of Greene began in December 2019 when the National Center for Missing and Exploited Children received a cyber tip that identified images of child pornography. Armed with a search warrant, agents from the Georgia Bureau of Investigation seized electronic devices from Greene’s Appling residence and discovered dozens of images and videos of child exploitation on those devices.

Greene was on probation for a prior conviction for drug possession at the time of his arrest on the child pornography charge.

“The GBI will continue to work tirelessly to protect innocent child victims of online exploitation,” said Michael Register, Director of the GBI. “We are grateful for the relationships we maintain with our federal partner agencies to bring these offenders to justice.”

The case was investigated by the Georgia Bureau of Investigation and prosecuted for the United States by Assistant U.S. Attorney Jeremiah L. Johnson and Assistant U.S. Attorney and Project Safe Childhood Coordinator Tara M. Lyons.
