As of Monday afternoon, the Iowa City Police Department identified a possible witness to a stabbing that occurred Saturday afternoon under the Benton Street Bridge south of Kinnick Stadium. According to police, the Iowa City police can only charge Williams at this time, and finding the witness would be paramount to making a conviction.

The suspect, Iowa City resident Yossarian Williams, 47, was arrested on Saturday at 1:28 p.m., eight minutes after the police reported the stabbing took place.

Iowa City police said the witness is described as a white or Hispanic man with a long beard, wearing blue clothes, and carrying a blue backpack.
