DUBUQUE, Iowa - It was a wild scene in a Dubuque courtroom Friday when a man convicted of murder assaulted a Dubuque County prosecutor as he was being led out of the courtroom following the verdict.

Michael Mayton, 41, was found guilty Friday of the lesser charge of second-degree murder in connection with the Aug. 15, 2009 stabbing death of David Tate.

As Mayton was being led away in handcuffs after hearing the guilty verdict, he swore and hit prosecutor Ralph Potter on the top of the head with his cuffed hands. Potter fell to the ground, bleeding from his head. Nearby officers tackled Mayton and took him out to a waiting police car.

Potter was taken away by ambulance, but was alert and talking. He was treated and released from a local hospital.

The Iowa Division of Criminal Investigation is investigating the incident and Mayton will likely face more charges.

During the two-week trial, Mayton admitted he stabbed his friend, Tate, but says it was an accident. Tate died at the hospital shortly after the incident.

Mayton was also charged with with attempted murder in the stabbing of Richard Schramm and he jury convicted him of the lesser charge of assault causing serious injury. Schramm was stabbed during the same fight, and survived.

Mayton faces up to 50 years in prison on the murder charge at his sentencing July 26. He would have faced life in prison without parole if he had been convicted on the first-degree murder charge.
