Conover said he had a "close relationship" with a Boy Scout from when the boy was 10 until he was 17, according to prosecutors. They were allegedly together after scout meetings, at Conover's house and office, and on some four-day road trips.
Investigators found a shoe box of scout-related photographs at Conover's home. The pictures were labeled with dates and locations, such as "Maine 8/99" and "Summer camp '91 Cape Hatteras."
Conover, who used the online name "petersneaks," apparently had a fetish for children's sneakers and wearing diapers.
In an online chat, Conover allegedly wrote: "last night I was outside in just a diaper . . . out front [of his house] . . . I soooo wish my neighbors son sees me . . . hes like 14."
Conover already had been under investigation by U.S. Immigration and Customs Enforcement's Homeland Security Investigations in the alleged trading of child porn on the Internet.
Harrington said Conover was registered as an assistant scoutmaster from 2002 until 2008, though he was largely inactive during that period and had moved to New Jersey.
Federal authorities said Conover was discovered during an investigation out of Boston that has led to about 45 arrests.
Conover had been released last Tuesday after posting $50,000 bail. He was arrested again Thursday after authorities allegedly found child porn on a computer at his house.
He has been ordered to remain in custody until a federal hearing Thursday in Camden.
If convicted, Conover faces a mandatory minimum of five years in prison and a maximum of 20 years, plus a $250,000 fine.
