Yvonne Hiller, 43, is accused of shooting and killing two co-workers at the Kraft Plant in 2010.
The murder trial for the suspended Kraft foods employee accused of shooting three co-workers, killing two of them, starts Monday.
Hiller is also charged with attempted murder for allegedly shooting and injuring 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.
