Von Stein, a Democrat who was elected as a first-time candidate to a four-year term in November 2015, did not respond to messages seeking comment. When comments were sought from his city council colleagues, only Vice Mayor Michael Ryan responded.

“I’m not commenting on this matter until more information is available,” Ryan said. “But I am against domestic violence, and violence toward women needs to stop.”

Butler County Democratic Party Executive Committee Chairman Brian Hester called the allegations against Von Stein “serious and troubling,” when asked about them.

“Upon learning about them for the first time this morning, my thoughts obviously are with the council member’s family during this difficult time,” Hester said in a statement to the Journal-News. “I will respect that the legal process will allow all sides to be presented before passing judgment and trust that our legal system will ensure that the truth and justice will be served.”

Von Stein received second-most votes in 2015 among five candidates who were seeking three council seats. The Badin High School and Xavier University graduate finished behind Carla Fiehrer and ahead of incumbent Kathleen Klink.

The police report indicates the alleged incident occurred at about 7 p.m. at the couple’s home.

In her witness statement, Nicole Von Stein stated, “we were with friends. They left then he went in and came out and got into his car. I went up to his car and asked him where he was going. He punched me in the face and left.”
