State crime lab now faces scandal

New accusations of missing drugs have now surfaced at a regional crime lab, potentially putting thousands of criminal cases in jeopardy.

The Central Valley Crime Lab in Ripon is part of the California Department of Justice.

It handles drug evidence for five counties in the Central Valley.

Investigators placed an employee on leave after a sample of crystal meth was weighed a second time and it turned out to be suspiciously lighter.

They're now reviewing drug cases dating back to 2006.

Thousands of drug cases in San Francisco have been thrown out in recent months after Deborah Madden, a crime lab employee, admitted taking cocaine from the lab.
