A suspended Kraft foods employee accused of shooting three co-workers and killing two of them was found guilty on Monday.
Yvonne Hiller, 43, was arrested after shooting two female co-workers in September 2010, according to investigators.
Prosecutors also say Hiller shot and injured a third co-worker.
Police say that the shootings happened minutes after Hiller was suspended from her job at the Kraft Plant following an altercation with the three victims.
They say she forced her way through security at gunpoint, walked into the employee lounge where the three victims were and shot them.
The jury reached a verdict late Monday afternoon. Hiller was found guilty of first degree murder. She is scheduled for sentencing on September 24 at 10 a.m.
