How would I find how to cite the below statement correctly? I'm confused when it gets to listing parties as Defendant-Appellant-Petitioner, etc.

Statement: State of Wisconsin, Plaintiff-Respondent, v. Robert Steven Zelenka, Defendant-Appellant- Petitioner, Ronald Scott Schilling and Thomas Daniel Stanton, Defendants, 1986 WI 132, 130 Wis.2d 34 at 39, 387 N.W. 2d 55 (Wis. Sup. Ct. opinion filed May 8, 1986).
