The man who walked into the Silicon Valley semiconductor firm SiPort in 2008 and shot and killed three of his managers was officially sentenced Friday.
A Santa Clara County Superior Court sentenced Jing Hua Wu, 52, to life in prison without the possibility of parole.
The sentencing hearing was supposed to start at 2:30 p.m., but was delayed. The courtroom was packed as many relatives of Wu's victims signed up to speak.
A jury in San Jose found Wu guilty of three counts of first-degree murder earlier this year following a trial that lasted more than two months.
The jury also rejected an insanity plea.
The former test engineer walked into the SiPort office on Nov. 14, 2008 and opened fire after begging for his job back.
The victims were SiPort CEO Sid Agrawal, 56, president of operations Brain Pugh, 47, and human resources manager Marilyn Lewis, 67.
The prosecution claimed the murders were premeditated by Wu, who bought 100 rounds of ammunition for his 9mm pistol following a morning meeting at the company and returned at 3 p.m. that afternoon to shoot the victims.
"The defendant deserves to be removed from society like the cancer he is," prosecutor Tim McInerny said.
Throughout the trial, Wu's attorneys argued that he suffered from a severe mental illness that ran in his family and that his at-times brutal life in Communist China during the 1960s caused distress that contributed to his state of mind during the slayings.
Wu testified that he did not remember killing the three victims, who were all shot in the head.
