WARMINSTER, Pennsylvania — A group of Pennsylvania men who dressed up as animals as part of a sexual fetish, have been charged with molesting a young boy repeatedly over the course of several years.

Authorities say the abuse began in 2009 when the boy was just 9-years-old and he was taken by David Parker of Stroudsburg, Pa., to a home in Bucks County where a group of men frequently gathered for “furry” parties.

Furries are people who dress up as animals. It usually involves elaborate costumes, artistic pursuits and video game culture, but for some, it also serves as a sexual fetish.

The boy, who is a relative of one of the men charged and now lives in foster care, told investigators that a man who dressed as a red fox and went by the the name “Lupine,” would take him upstairs at the parties and molest him. Police identified the man as 57-year-old Kenneth Fenske, of Quakertown.

Fenske was arrested Friday and charged with child rape, involuntary deviate sexual intercourse and unlawful contact with a minor. He is being held on $750,000 bail.

In all, five men were arrested. Parker, 37, was also charged with child rape, possession of child pornography and other charges. Jeffrey Harvey, 40, of West Wyoming, Pa., is charged with unlawful contact with a minor, criminal use of a cell phone, involuntary deviate sexual intercourse and statutory sexual assault

Craig Knox and Stephen Taylor, both of Virginia, have also been arrested in connection with the case. Knox is charged with sexual offenses and Taylor was also arrested for bestiality and other related offenses, investigators said.

“This is a horrendous case,” Pennsylvania Attorney General Josh Shapiro said. “It is deeply disturbing to me not only as Attorney General of Pennsylvania, but as a father of young children.”

He said he expects there will be further arrests in connection to the case and that there may be other victims of the furry ring.

Investigators first learned of the ring in June, when they arrested Harvey as he arranged online to meet a person he thought was a 13-year-old boy, but was actually a cop. That led them to Parker, which led them to the victim, who told them about the furry parties.
