Police say the victim is a man in his 30s and they have been talking to witnesses, but so far there have been no arrests.
A business is an unusual place to find a homicide victim, especially on Lundy Avenue in San Jose. People say late hours are rare for workers in the office building where several different types of businesses are located.
A man with at least one gunshot wound was found inside just before 1 a.m. Thursday. He was taken to the hospital where he died.
Workers arrived Thursday morning and were kept out of their offices because of the homicide investigation.
"When I just come this morning at 6:45 a.m. the guy told me somebody was killed inside the building and that scare me," Lieu said.
"It's a shock. I wouldn't, I don't know what's going on. Yeah, it's a surprise," said Kieu Do, another worker.
Police taped off a huge section of buildings on Lundy Avenue, including the Church of Scientology. They also checked for surveillance video.
Workers at the building where the body was found were told around 9 a.m. to go home. Their building would be closed all day for the homicide investigation.
"We're in an industrial area and I've never had any problems. I've never had any break-ins. Never any issues. I hope that this doesn't continue something like this," said David Gordon, a worker.
There have been 11 homicides in San Jose over the past six weeks.
