More details emerge after raid on Subway pitchman Jared Fogle's home

ZIONSVILLE, Ind. -- A week after FBI agents raided the Indiana home of Subway pitchman Jared Fogle, more details are emerging about the child pornography investigation that led authorities to his home.

Fogle has not been arrested or charged and some close to Fogle say that is because nothing sinister was found in his home in Zionsville, north of Indianapolis.

U.S. authorities have not acknowledged that they are investigating Fogle, much less indicated whether Fogle is a target or why. But there are two things that that may shed light on the case.

First, Russ Taylor, the leader of Fogle's child-obesity foundation, may be cooperating with federal authorities. Taylor has been held since May on charges he produced and possessed child pornography.

In court records, weeks before Fogle's home was raided, Taylor agreed to suspend his right to a speedy resolution of the case to allow investigators more time to prepare charges. Taylor was turned in by a female acquaintance, who he allegedly asked in a text message if the pair could engage in bestiality. The woman told investigators she received an image file via text from Taylor that depicted bestiality. A search of his home turned up 500 videos and a shocking trove of child porn-some images of children as young as 9.

A second detail is from a former Florida journalist who told ABC in Sarasota that she met with Fogle numerous times the past decade during his promotional visits and that he made numerous inappropriate comments about middle school girls.

"The subject matter is similar to what the FBI found when they raided his home but it goes deeper than that," said the woman who asked not to be identified. She said she eventually called the FBI, wore a wire and recorded phone conversations with Fogle.

"That's exactly what started this," the woman said. "When I presented it to the FBI the first thing they said to me is, 'This who I think it is?' I said 'Yes, it is.' And it just went in full gear after that."

Fogle's attorney told ABC in Sarasota that the woman's account is an "unrealistic fabrication." He said Fogle is cooperating, but declined further comment.

Lawyers for the foundation also declined comment.
