A Philadelphia jury on Monday watched surveillance video of a disgruntled Kraft employee shoving a gun into the security booth outside the factory where two of her co-workers were gunned down minutes later.

But the focus of opening arguments in the punitive damages trial in Wilson v. U.S. Security Associates was not on the shooter, Yvonne Hiller, but instead on the conduct of two security officials in the few minutes both up to and after Hiller brandished the .357 revolver at the security booth and passed into the factory.

According to Kline & Specter attorney Shanin Specter, the security supervisor for U.S. Security Associates on-site failed to properly escort Hiller to her car, and then, after she returned with the gun, he ran to the boiler room and hid instead of notifying employees inside the building.
