Add a shattered window to the list of possible structural issues that has plagued Santa Clara County's crime lab.
The county paid $75 million for the state of the art lab, which opened in 2009. That was also the year building problems started at the lab.
A faulty seal on a rooftop pump broke and forced a leak. In 2013, two civil grand juries investigated and uncovered bacteria in a water pipe. The bacteria found could cause Legionnaires' disease, officials said.
Most recently, county workers this week discovered a shattered glass panel on the east face of the crime lab. Vandalism does not appear to be the cause of the broken glass.
Santa Clara County Supervisor Dave Cortese said he had not been told about the glass panel. If it's a structural issue at the lab Cortese said he would be very concerned.
"This building (when constructed) was celebrated as best in its class," Cortese said in a text message to NBC Bay Area. "If there are defects, we'll get to the bottom of it."
