MENOMONIE, Wis. (AP) — Prosecutors in western Wisconsin are trying to prove a woman accused of fatally stabbing her ex- boyfriend staged a phony crime scene in an attempt to claim self-defense.

Ezra McCandless is accused of stabbing Alex Woodworth 16 times, killing him in the backseat of her car parked along a rural road in Dunn County in March 2018. The 22-year-old defendant says she killed Woodworth after he forced himself on her and cut her clothing with a knife which she wrestled from him and used against him.

KARE-TV says the jury on Tuesday was shown a shirt and sweater that were cut or ripped. District attorney Andrea Nodolf attempted to show the jury that the weapon that killed Woodworth belonged to McCandless’ father.

The trial is expected to last through next week.
