PHILADELPHIA — A former Kraft Foods employee was convicted Monday on two counts of first-degree murder for a 2010 shooting at a Nabisco cookies and crackers plant in Philadelphia, The Bellingham Herald reported.
The defendant, Yvonne Hiller, was suspended on Sept. 9, 2010 for threatening coworkers. She returned minutes later armed with a gun and shot three employees.
Co-worker Bryant Dalton survived the attack, but two others — Tatonya Brown and Tanya Wilson — were killed.
According to witnesses, Hiller experienced paranoid delusions and often complained that coworkers were spraying her with chemicals and were intolerant of her Muslim religion.
Hiller waived her right to mount an insanity defense and prosecutors agreed not to seek the death penalty. She was found of all charges related to the rampage and faces a mandatory life sentence.
Hiller’s formal sentencing is set for Sept. 24.
