A state appeals court has upheld the conviction of a Plover man who'd been found guilty of killing a truck driver 10 years ago.
Michael Haydon was convicted of killing Pat Zemke in the cab of Zemke's truck in 2003. Prosecutors alleged that Haydon mistook the victim for another truck driver whom Haydon suspected of having an affair with his ex-girlfriend.
A jury convicted Haydon. He appealed the decision, saying the state shouldn't have been allowed to introduce testimony that his ex-girlfriend had given in a separate case.
The woman had testified Haydon sexually assaulted her hours before the killing. An appeals court on Thursday concluded that the testimony was relevant and properly allowed.
Haydon's defense attorney, Dennis Schertz, says he's disappointed in the decision and will confer with Haydon on next steps.
