In what has to be the most unfortunate case of temporary insanity, Jing Hua Wu, who went berserk and shot three co-workers at the radio chip maker Si Port, is going to be arraigned in San Jose this Wednesday.

I certainly hope this is the only case of it's kind for a long as there's a poor economy. Wu killed his fellow employees, Marilyn Lewis, 67, of San Jose, the company's head of human resources; Brian Pugh, 47, of Los Altos, vice president for operations; and Sid Agrawal, 56, of Fremont, the company's co-founder and chief executive, after he learned he was going to be fired.

I don't understand why this father of three would do that, but as TechCrunch put it , it's a sad day in Silicon Valley.
