A Jamestown man will spend at least the next two decades in prison for the July 2018 shooting death of William J. Michishima.

David F. Waggoner received an indeterminate sentence of 20 years to life in prison Monday in Chautauqua County Court by Judge David Foley. The city man was found guilty in March on a charge of second-degree murder.

Waggoner shot Michishima July 24, 2018, on Livingston Avenue following an argument between the two men.

Michishima, who was shot in the head, was transported to UPMC Hamot in Erie, Pa., where he died the following day.

Waggoner was represented by Chautauqua County Public Defender Ned Barone.

Barone maintained throughout the trial that Michishima was the aggressor when he visited Waggoner at his Livingston Avenue home. Two witnesses described seeing the men fight before Michishima was shot in the head.

“Obviously it’s always a disappointment, of course, when you believe that you may have been in a position to receive a different verdict,” Barone said at the time. “However, we still strongly believe that we presented a case for justification, and we’re of course disappointed with what the jury had decided.”
