Five St. Lawrence County men face a total of 455 counts of child pornography and weapons charges following a year-long investigation that involved the alleged sexual exploitation of kids.

Investigators are calling the case "disturbing and disgusting."

Charged were 39 year old Michael Delamontagnes of Brasher, 62 year old Mark Nezezon of Brasher, 30 year old Jeremy Cyrus of North Lawrence, 29 year old Jonathan Delosh of Norwood and 32 year old Jeremiah Rose of Massena.

The suspects were rounded up Wednesday.

During what was known as "Operation Northern Net" - an ongoing nationwide child porn sting - Immigration and Customs Enforcement (ICE) agents and local  authorities seized computers and computer hard drives from the suspects' homes.

"The images were very detailed and very graphic, some being infants having sexual relations with adult males," said Sheriff's Deputy Sean O'Brien.

"Very inappropriate material," he added.

Using a high-tech security network, authorities were able to target alleged child sexual predators and track their exchanges and downloads of child pornography.

Authorities don't believe any images of local children were used.

"Through all the cases, we're talking over thousands of images," O'Brien said.

Delamontagnes faces 132 felony counts of promoting an obscene performance of a child and 132 counts of possessing an obscene sexual performance of a child.

Nezezon was charged with 39 counts of promoting the obscene performance of a child under 17 years old and 39 counts of possessing an obscene sexual performance of a child.

Cyrus was charged with 124 counts each of promoting a sexual performance of a child and possessing an obscene sexual performance of a child. Cyrus also faces a weapons possession charge.

Delosh was charged with 10 counts each of promoting the obscene performance of a child and possessing an obscene sexual performance of a child.

Rose was charged with one count of promoting and possessing an obscene sexual performance of a child and two counts of criminal possession of a weapon.

All five were arraigned in Potsdam town court and committed to jail on $5,000 bail each.

A preliminary hearing is tentatively scheduled for Monday.
