Yvonne Hiller Suspect in Kraft Shooting: Two Killed, One Wounded at Philadelphia Plant

PHILADELPHIA (CBS/AP) Disgruntled over her recent suspension, a Kraft Foods employee opened fire inside the Philadelphia plant where she had worked for the past 15 years, according to police. Her rampage claimed the lives of two of her fellow workers and critically injured another.

Police say Yvonne Hiller was escorted off the plant premises around 8:30 Thursday evening and within minutes had returned armed with a .357 Magnum. She drove her car through a barricaded security checkpoint, re-entered the building on foot, and took aim, reports The Philadelphia Inquirer.

As she walked inside, she fired a shot at an employee who had followed her in and had yelled, "Hide, she's got a gun!" Lt. Frank Vanore said.

That shot missed its mark.

Hiller proceeded to the third floor where she shot and killed two female employees whose names have not yet been released.

The third victim, an unidentified male, was also shot in a stairwell and remains in critical condition, say police, according to The Philadelphia Inquirer.

Police were alerted of the shooting by an employee who was trapped inside the building. Within minutes, police had surrounded the six story building.

Hiller was taken into custody by SWAT team members about an hour after the shootings began.

It is remains unclear why Hiller was suspended and whether the victims were targeted or random.

Kraft has issued a brief statement.

"This is a sad day for the Kraft Foods family. Our thoughts and prayers go out to their families. The loss of a loved one is a great sorrow."
