OSHKOSH - A former Oshkosh man previously sentenced to probation after he was accused of sexually assaulting children faces new federal charges after police say he tried to meet someone he thought was a 14-year-old girl for sex.

Tommy Lee Jenkins, 32, who recently moved from Oshkosh to Whitestown, Indiana, was arrested by local and federal authorities, according to U.S. Attorney Matthew Krueger of the Eastern District of Wisconsin.

Jenkins began exchanging instant messages with a person he thought was a 14-year-old girl on Oct. 1, according to the Justice Department. The person was actually an investigator with the Winnebago County Sheriff's Office.

At some point, Jenkins suggested the "teen" come to Indiana and talked about getting drunk together, according to court documents. He then started talking about sex and asking for and sending sexually explicit photos.

When the person refused to meet him in Indiana for sex, he said he started walking 371 miles from Whitetown, Indiana, to Neenah to meet her for sex, according to the Justice Department. He continued sending photos of himself along the way, and on Thursday said he'd made it to Milwaukee, where someone bought him a bus ticket to get to Neenah.

Jenkins said he'd like to have 500 kids with the "teen," including one within a year, according to court documents.

When Jenkins arrived in Winnebago County, sheriff's deputies and FBI agents arrested him, according to the Justice Department.

In 2011, Winnebago County prosecutors charged Jenkins with two counts of repeated first-degree sexual assault of the same child, but those charges were later reduced to four counts of child abuse. He was sentenced in 2012 to four years of probation.

According to court documents, between July 1 and Sept. 30, 2011, a 7-year-old boy told a Neenah police investigator in 2011 that Jenkins would grab or rub his genitals and tell him they both would get into trouble if he told anyone.

An 8-year-old boy also told police Jenkins would squeeze his genitals and buttocks and tell him police would arrest the boy if he ever told anyone, according to court documents.

When an investigator interviewed him, Jenkins said nothing had happened and that both both boys were "making the whole thing up," according to court documents.

Jenkins later pleaded no contest to four reduced charges of child abuse by recklessly causing harm and was sentenced to four years of probation, according to court records. A 360-day jail sentence was stayed.
