An Allegheny County judge on Monday upheld the guilty convictions of four people arrested during the G-20 summit in September.

Five people had hearings before Senior Common Pleas Judge Robert C. Gallo to appeal their convictions on summary charges of disorderly conduct.

Four of those who appealed their convictions were arrested during a mass sweep on Sept. 25 on Schenley Plaza in Oakland.

Judge Gallo affirmed convictions of:

• Peter Vankoughnett, 20, of Minneapolis, who had pleaded guilty to disorderly conduct, and was ordered to pay $423.50.

• Anna Rasshivkina, 21, of Pittsburgh, also pleaded guilty and was ordered to pay $223.50, and

• Jonathan Latourelle, 26, of Pittsburgh, was found guilty at trial and ordered to pay $223.50.

Judge Gallo did not sustain the conviction of Jason Muley. Mr. Muley, 22, of Pittsburgh, also previously pleaded guilty and was ordered to pay $373.50. But the judge on Monday found that prosecutors were unable to proceed with specific testimony regarding Mr. Muley's actions on the plaza.

One other person appealed a disorderly conduct charge from the Sept. 24 afternoon protests in Lawrenceville.

Karen Switzer, 37, of Pittsburgh, was found guilty at trial of one count of disorderly conduct, and ordered to pay the court $154.50. Judge Gallo affirmed that conviction, as well.

More than 100 people were arrested the night of Sept. 25 in Oakland after, police said, a large group that had gathered failed to heed instructions to clear the area.

Many of those swept up by the hundreds of police officers who had gathered in the area in riot gear were students at the University of Pittsburgh.

The Allegheny County district attorney dropped charges in some of those cases. In dozens of others, students agreed to complete community service to have their cases dismissed by the court.

Still others who were charged agreed to plead guilty and pay fines.

More appeal hearings are scheduled today.
