Armed with 46 pages of questions, prosecutor Tim McInerny on Thursday continued cross-examining a former SiPort engineer, poking holes in his claim that he shot his bosses to death in a moment of madness.
The engineer, Jing Hua Wu, insists he wasn't angry at his three bosses for firing him in November 2008, merely in despair about his financial situation. He intended to kill himself in front of them when the gun went off, wounding his immediate supervisor. Then, Wu has said, he went into a fugue state. He testified a day earlier that he can't remember shooting them to death in the office of the Santa Clara startup, and has pleaded not guilty by reason of insanity.
But McInerny relentlessly hammered away at that explanation Thursday, suggesting that Wu couldn't stand his immediate supervisor, Brian Pugh, and intentionally killed him, as well as office manager Marilyn Lewis and CEO Sid Agrawal, out of long-simmering rage.
"You felt Brian Pugh was always looking over your shoulder, checking your work," the prosecutor asked. "You told (a co-worker) that Brian Pugh was 'a liar, not an honest man.' ... You told a doctor he was a 'very mean man' and that he did not show 'very upright behavior, like a thief.' "
Wu was humiliated when Pugh repeatedly claimed he missed deadlines for testing HD radio chips, the prosecutor said, building the case that Wu was fired for cause, not unfairly as he has insisted. Pugh also reassigned some of Wu's
In a particularly bizarre incident, Wu brought one of his 6-year-old twin boys with him to Teradyne's testing center in San Jose, then parked the child in the cafeteria alone for hours. Teradyne's regional manager warned Wu not to do it again, but Wu brought the boy in with him again a couple of days later anyway.
Wu wound up locking his son in the car briefly with the windows rolled up despite the 90-degree heat, prompting the manager to call police. Once again, Pugh upbraided Wu, this time for jeopardizing SiPort's relationship with Teradyne, McInerny said.
Pugh also wrote an email to Agrawal, Lewis and another executive, detailing the engineer's threatening comments to him shortly after Pugh told Wu he was being let go. The threats were made just hours before Wu left SiPort to buy bullets, came back and committed one of Silicon Valley's worst workplace killings.
According to McInerny, Wu vowed that Pugh "would not escape from Earth and that he should go to hell."
