Synopsis by Hal Erickson
A severed head is found in the trunk of car on the day that the CSI is to be evaluated by the Vegas police. Not long after, a headless body is found in the desert. Could there be a connection? No: the head and body are most decidedly a "bad fit" -- and apparently not even from the same species. Elsewhere, Warrick (Gary Dourdan) investigates when his friend James (Samuel L. Jones III) witnesses a murder while in juvenile detention.
