Synopsis by Hal Erickson
Five people are killed in a bungled grocery store robbery that escalates into a shooting spree. Investigating, the CSI members find that one of the victims was a police officer. The case is complicated when Grissom (William L. Petersen) encounters resistance from another cop who apparently suffers from a persecution complex. Further muddying the waters is the evidence found at the crime scene -- rather than not enough evidence, there is far, far too much.
