PHILADELPHIA (CBS) – A Philadelphia woman was convicted this week of the Kraft plant gun rampage that killed two employees and wounded another who were cornered in a break room. (see related story)

The disturbing trial evidence also proved the extraordinary bravery of fellow employees who prevented further bloodshed.

About a hundred employees were inside the landmark building when defendant Yvonne Hiller entered with a gun.

Almost immediately, employees risked their own lives to try to save others, steering them outside or to safer locations inside the building. And then there’s David Ciarlante, a mechanic at the plant. Prosecutor Gail Fairman.

“Ciarlante followed Yvonne Hiller through the plant, trying to warn people where she was,” said prosecutor Gail Fairman.
At one point he tried to convince her to surrender….she fired at him, but missed.

“When the police came he was scared but he helped them. They were there with big shields at first, and he went with them even though she was still in the building to turn off the ovens so they could communicate with each other, the sound was so noisy,” Fairman explained.

Hiller also fired at others who tried to track or thwart her before she was eventually cornered by police and arrested.
