The Las Vegas Crime Lab is a scientific laboratory located in Las Vegas, Nevada, which uses primarily forensic science for the purpose of examining evidence from criminal cases while determining who is responsible for the crime that has been committed.

Employees of the Crime Lab are known as criminalists; this includes both CSIs doing mostly field work and lab techs doing mostly lab work.

CSIs are equipped with guns in the field, but are not considered police officers. CSIs often mention this to suspects to make them feel more comfortable.

The Crime Lab is headed by Sheriff Conrad Ecklie and reports directly into the Sheriff's office. Ecklie was once the Assistant Director and also former Day Shift Supervisor of the Crime Lab, but was promoted to Undersheriff after former Undersheriff Jeffrey McKeen was arrested for killing CSI Warrick Brown in the Season 9 opening episode, "For Warrick", and eventually got promoted to Sheriff.

In addition, all CSI personnel, including some of the techs, wear stab proof vests while in the field, which have multiple pockets to hold items they need for collecting evidence, as well as the CSI's last name.


The Crime Lab has three shifts:

  • Day Shift - 7 am to 3 pm
  • Swing Shift - 3 pm to  11 pm
  • Night Shift - 11 pm to 7 am
