The network is planning for the finale of the series during the 2015-16 season. The drama revolves around a group of Las Vegas-based criminalists and investigators who examine physical evidence to solve murders.
Although the drama has been often criticized for its violence and images, it has been a reliable hit for the network since its premiere in October 2000, and is one of the most popular shows internationally.
The series has also survived several cast upheavals and the departure of original lead William Petersen.
Laurence Fishburne joined the cast in 2008, replacing Petersen. After two and half-seasons, Fishburne announced he was leaving. He was replaced in 2011 by Ted Danson, the current lead.
