CSI: crime scene investigation

“Gil Grissom” (William Petersen)

Grissom is the head of the Las Vegas Criminalistics Bureau. An investigator of the old school with 17 years on the job, Grissom eschews computer simulations and readouts for the old-fashioned, hands-on technique and legwork. CSI is his life. He supervises a team of very diverse professionals on the night shift, and Grissom goes to the wall to protect
them from department interference - and sometimes, from the consequences of their own risky decisions, on and off the job. Currently, he is struggling with a congenital hearing disorder, the extent of which he doesn’t completely understand, and which he takes pains to hide from his colleagues.
