The felonious assault case against Robert S. Lewis, a former president of the fraternity Delta Upsilon, was dismissed Friday in a motion by the prosecution.

The case has been withdrawn until the victim, Lewis’ ex-girlfriend Amanda M. Linna, is better able to assist with the prosecution, Portage County prosecutor Stephen Michniak said at a pretrial hearing at the Portage County Court of Common Pleas. Linna has suffered new trauma that may be linked to the alleged assault, he said.

Lewis, 22, was arrested September 24 at his parents’ home in Dover following the alleged incident at the Delta Upsilon fraternity house, located at 202 S. Lincoln St., on September 21. Police say Lewis had a knife in his possession at the time of the reported assault.

He was indicted by a grand jury September 27 on the second-degree felony charge.

Lewis pled not guilty at his arraignment on September 28. His original trial was scheduled for December 4, but it was subsequently postponed three times. The trials were rescheduled due to scheduling conflicts and, once, according to court documents, because the prosecution didn’t give the defense information it had requested.

The case is expected to return to court, Michniak said during the pretrial Friday.
