Haysville husband and wife admit to possessing child pornography

WICHITA - A Kansas couple admitted culpability in crimes related to child sexual abuse material (CSAM).

According to court documents, Addilynn Jean Onuffer, 22, of Haysville was sentenced to 160 months in prison after pleading guilty to distribution of child pornography.

Her husband and co-defendant Gavin Onuffer, 27, pleaded guilty to one count of receipt of child pornography. He is scheduled to be sentenced August 3, 2026.

The National Center for Missing and Exploited Children (NCMEC) received a cyber tip about CSAM from an IP address connected to the home of Gavin and Addilynn Onuffer. Investigators obtained a search warrant for Gavin's cell phone and found files containing images of prepubescent minors engaged in sexually explicit conduct. Evidence showed his wife sent him the images.

"In her plea agreement, Addilynn said she sent her husband CSAM images simply because he wanted them," said U.S. Attorney Ryan A. Kriegshauser. "We all have a duty to protect the most vulnerable members of our society. Instead of holding each other accountable and stopping perverse activity, this couple engaged in their prurient interests together. There is no excuse for this behavior."

The Kansas Internet Crimes Against Children Task Force (ICAC) and Wichita Police Department investigated the case.
