A Slippery Rock man who caused a courtroom ruckus last year will find himself in sentence court again.

A Butler County jury Wednesday convicted 43-year-old Robert W. Dunkel Jr. of aggravated assault, simple assault, obstruction of justice and resisting arrest relating to the Feb. 24 debacle.

Then, Dunkel was among about 40 defendants scheduled to appear in the courtroom of Judge William Shaffer to be sentenced.

He earlier had been found guilty of a summary count of harassment for his conduct toward a student at Slippery Rock University in 2013. At the time, he was attending SRU.

Assistant District Attorney Ben Simon, one of eight witnesses called during Dunkel’s trial this week, testified that during the sentencing court, the harassment victim, a woman in her 20s, was first asked to speak.

The woman, Simon testified, was visibly upset when it was her turn to tell the judge how the crime impacted her life. About a minute into the woman’s statement, Dunkel began “making weird noises,” snorting and trying to “stare down” the woman, Simon said.

County Deputy Sheriff Eric McLafferty first stood behind Dunkel to send him a message, Simon said. But Dunkel became increasingly agitated and at one point reached out at the deputy.

McLafferty, Simon said, asked the defendant to take a seat to calm down.

Dunkel’s level of agitation continued to increase, and eventually he ended up on the floor in a scuffle with McLafferty and two other deputies. The deputies were armed.

During the scuffle, Deputy Codi Csellar was cut on a finger.

Dunkel, arrested at that time, was sentenced for the harassment conviction a month later. His sentence was 90 days in jail.

During this week’s trial, Dunkel’s defense attorney, Armand Cingolani, tried to convince the jury that his client was only a perceived threat because he was trying to assert his innocence, in affect bucking the system.

Cingolani said part of the problem was that his client had been convicted of harassment in absentia and was eager to assert his innocence.

Dunkel, who appealed the conviction, reportedly later went on a hunger strike while incarcerated to protest the sentence.

Cingolani alleged that society, based on the circumstances, automatically vilified his client and coddled the college girl.

He called it the case of “Little Red Riding Hood, the wolf and too many huntsman.”

For the new conviction, Dunkel will be sentenced March 24.

Cingolani said his client already is planning an appeal because “I don’t think there was an aggravated assault, and I don’t think being tackled by a bunch of sheriff’s deputies constitutes obstruction of justice.”

Initially, Dunkel faced additional assault charges that the judge dismissed.

The case was prosecuted by the state attorney general’s office because members of the county district attorney’s office were called as witnesses.
