A Lancaster man will keep his trial date and face a jury on Tuesday after he pleaded not guilty Thursday morning in Delaware County Common Pleas Court to an additional nine charges of unlawful sexual conduct with a minor.

Brent Plummer, 26, entered a not-guilty plea Thursday morning to nine counts of unlawful sexual conduct with a minor, which are third-degree felonies, in Delaware County Common Pleas Court.

He had previously entered a not-guilty plea to nine counts of rape, which are first-degree felonies, and three counts of gross sexual imposition, which are fourth-degree felonies, but was indicted on the nine unlawful sexual conduct charges on June 17.

Gormley accepted his not-guilty plea and said he would face the nine new charges at his trial for the other 12 charges on Tuesday, June 28.

The trial is expected to last two days.

According to the indictment, between Jan. 1 and Feb. 22, Plummer sexually assaulted a Delaware County girl. Genoa Township police said in February that the girl was 14 at the time of the alleged crimes. Prosecutors said the charges cover three specific incidents in that time period.

Plummer was in the Delaware County Jail Friday, awaiting his trial. He is represented by Delaware public defender Scott Wolf.

Gormley continued Plummer’s $75,000 bond — which was set in Delaware Municipal Court on Feb. 25 — and stipulated that if he is released, he is to have no contact with the alleged victim, a 14-year-old from Genoa Township.

Genoa Township Police Sgt. Rich Lyon said March 3 that an investigation of Plummer began after another party came to the township police department with the victim and asked to file a report.

After the complaint was filed, a warrant for Plummer’s arrest was issued.
