last of three high-tech executives gunned down in their Silicon Valley office was laid to rest Friday

last of three high-tech executives gunned down in their Silicon Valley office was laid to rest Friday as friends, families and co-workers struggled to make sense of what they called an incomprehensible crime.Funeral services were held in Los Altos for Brian Pugh, 47, vice president of operations at SiPort in Santa Clara before he and two co-workers were slain Nov. 14 by an engineer who had been fired from the firm earlier in the day, police said.The company's chief executive, Sid Agrawal, and human resources director Marilyn Lewis also were killed. Suspect Jing Hua Wu, 47, of Mountain View, who was arrested last Saturday, could face the death penalty if convicted. On Friday, hundreds of mourners packed the Los Altos United Methodist Church to honor Pugh, a soft-spoken father of two who loved music, the outdoors and playing with his kids."Obviously, the last few days have been very difficult. This isn't something you can ever expect to happen," said Pugh's widow, Carol Coe Pugh of Los Altos. "But we've received enormous support from the community and the SiPort family."SiPort, a 4-year-old startup that makes wireless chips, is a close-knit firm of 38 Silicon Valley veterans who've been devastated by the killings, said vice president of marketing Sunder Velamuri."I cannot describe to you the shock," he said Friday, just as Pugh's service was getting under way. "It's surreal. People are walking around like they're in a dream. I still expect to hear Marilyn's laugh in the hallway."The staff has been undergoing grief counseling when not attending funerals, and is gradually getting back to work. The firm has had a successful year, and its clients have been highly supportive through the tragedy, said company spokeswoman Ching Wu.Still, the grief and shock will never completely fade, Velamuri said.
