Synopsis  

Grissom, Sara and Warrick investigate when a bomb goes off in a Vegas office building, killing a security guard. The prime suspect is another security guard, who is over-helpful and also has the knowledge to make a bomb. Elsewhere, Kristy Hopkins is killed after Nick spends the night with her. With his DNA and fingerprints on the scene and Ecklie on the case, Nick’s career is on the line.

Review  

At the bomb scene, Sara is wrapped up against the cold. Sara and Catherine examine the bomb debris at the lab, then Grissom has Sara check out an orange substance melted on to the clock gear of the timing device. Grissom is experimenting with alarm clocks, trying to find out what type was used in the bomb when Sara walks in with information pulled from the bomb database, listing what the most popular brand of clock is for timing devices.

Sara and Grissom blowing up bombs to determine the container components (Sara seems to get a little kick out of this). Sara determines that the orange substance is polyester. Another bomb goes off, and Sara takes an orange jacket from a worker at the scene. Sara discovers the jacket material is identical to that of the melted goo in the bomb, and searches the database for that company to find a disgruntled (and out of work) employee. Sara and Brass arrest the disgruntled former employee.

Notes  

• Sara appears to be a little more helpful than usual when it comes to Grissom.
